Proper threading of the bobbin, hook and bobbin thread in the sewing machine
People are increasingly favoring sewing machines and moving away from hand sewing. The latter is often used by professional craftsmen only in cases where you need to stitch dense material with an awl or thick needle. Sewing machines have a lot of moving parts, so you need to know how to properly care for them so that the process of work is as enjoyable as possible. Among these elements is the most important element. the bobbin. This material will tell you how to tuck the bobbin into the sewing machine and what it is in general.
After studying the design elements of the equipment and before how to correctly thread the sewing machine, you need to prepare the basic working tools:
The first step in threading is winding the bobbin, a compact bobbin designed to feed the thread from below.
Threading the bobbin
To properly tuck the bobbin into the sewing machine, you need to perform the following steps:
- Plate under the needle is withdrawn and remove the bobbin from the operating mechanism. The bobbin must be free of thread residue.
- There are rods on top of the machine to install the bobbin. The bobbin is slipped onto the extended spool pin so that the thread rotates counterclockwise
- Thread is pulled through the tension disk and wound around the bobbin in several circles.
- The bobbin is installed on a short rod and secured
- Winding is automatic (pedal or button on the body), depending on the configuration of the sewing machine
- After winding is complete, the lock is pulled away, the bobbin is removed and the thread is carefully cut with scissors.
- Insert the wound bobbin into the hook
Threading the hook
After the thread is wound onto the bobbin, it must be set into the metal hook correctly. How to tuck the hook into the sewing machine in this case? The shuttle mechanism is installed in the inner part of the platform, located under the needle. To do this, unwind the bobbin thread at the free tip of 8-10 cm and pull through the entrance hole in the hook. The bobbin is installed in the hook, which is tucked into the hook slot. On the top of the shuttle is a hook for docking with a hollow in the socket. After several rotations of the sewing machine handwheel, the lower bobbin thread is taken out, and then the protective plate on the platform is closed.
Threading the upper thread
Once the bobbin is properly wound and installed, the next step is to learn how to tuck the upper thread into the sewing machine. It is threaded from the spool to the needle eye. The threading procedure is quite simple and follows the diagram:
- Presser foot raises, needle and thread guide with the flywheel set in the upper position.
- The spool is secured on the spool pin
- Thread is guided from the spool through the upper thread guide to the thread tensioner
- The thread is pulled between the tensioner elements and comes back up to the second thread guide part. In this case, the thread must be pulled taut in the shape of an English letter “U”
- It is then threaded through the tensioner and led to the eye of the needle
- The upper thread is inserted into the eyelet and threaded through the presser foot mounted under the needle. The tip of the thread is directed to the opposite side
- Upper and lower threads are pressed by the foot to the work platform
Threading the thread into the sewing machine
Before the thread is threaded into the needle eye of the sewing machine, it is passed through some fixing holes. This prevents it from tangling and breaking. Slightly tugging off the tip, the thread is pulled through the eye of the side tensioner and the rounded catch below. Then it is threaded into the eye of the needle.
Important! Proper tension of the upper thread will prevent thread breaks and help keep the stitching straight.
Janome sewing machine with swinging hook
This model of a sewing machine Janome has a swing type hook. Such a hook uses only Janome, but also other companies sewing machine manufacturers. This machine initial price, which you can buy in the range of 4-5 thousand. They are quite reliable and “hardy”, but there are limits to everything and here after it was on this machine (photo) decided to hem several jeans at once she was in our shop.
Look at the photo. Arrows indicate the hook nose and needle eye. You can see that when approaching the hook nose to the needle, the eye of the needle is too high, and therefore not formed stitches. This is a very common “breakage”. In quotes, because such a failure occurs if you do not respect the rules of operation of any sewing machine, and Janome is no exception. It is not even a malfunction, but a violation of the parameters of interaction between the hook mechanism and the needle. Occurs at a time of excessive load. And the finishing stitch on the hems of jeans is exactly the case. Toothed belt, connecting the upper and lower shaft “slips on a tooth” and the machine ceases to form stitches, although it is still operating normally. Jeans are probably the biggest “enemy” of all sewing machine manufacturers. How much they undermine the image of any of them. After all, it is jeans that most often put household sewing machines out of order.
To understand why this happens, and why you can not hem jeans on domestic sewing machine count how many layers of tissue formed at the roughest place (joint seams). 9 to 12 layers. Take the needle and try to pierce such an area with a hand needle, it is unlikely to succeed. Only if the needle is hammered.
Vertical “oscillating” sewing shuttle
Vertical “oscillating” sewing shuttle, we can say the classic type of shuttle, which performs oscillatory movements during operation. This type of hook is used, for example, in a sewing machine Chayka. Podolsk and most of the older editions of sewing machines.
The word sewing shuttle itself came from the first type of this device. You can also see such machines with some housewives. In such machines, the thread from the needle takes off the most real shuttle, “long bullet”, which is inserted into the same long bobbin. That’s what replaced the swinging shuttle in the future, and it is used to this day.
Such an excursion into history will help you decide what to buy a sewing machine. and which type of hook to choose.
Swinging sewing shuttle is not designed for high speed operation and, as a rule, it is used in domestic sewing machines inexpensive models of economy class. Its advantage is that many parts are interchangeable and universal. For example, you can easily pick up the bobbin case, and even the hook. But it is true, the need for this appears very rarely, and if you do not pull the fabric when sewing, when the needle hits the spout hook and bobbin cap, then it will serve very long. Sometimes wrongly used terms, calling the bobbin hook (with a spout), and the bobbin case (with a tail) shuttle.
Vertical sewing shuttle or “double hook” is mainly used in the design of industrial machines, but also found in domestic expensive models of sewing machines. See. Vertical hook sewing machine.
Of the old Soviet domestic sewing machines this type of shuttle installed in a German sewing machine “Veritas”, though not all models. Many owners of these machines, not even knowing what type of hook the machine has, perfectly use them to this day, wondering what a good machine. Of course, it’s not just the type of sewing shuttle, but, nevertheless, this is a decisive factor if you’re going to sew a lot on your machine and sometimes rough, thick fabrics.
However, this does not mean that since this type of shuttle is worth it, you can sew a leather coat on a domestic sewing machine. The thickness of the fabrics that can be sewn with a particular sewing machine depends on other important factors, as specified in the manual. Do not violate the requirements of the manufacturer, if only because the machine may have plastic gears and from the increased load they simply break. See. Repairing leather clothing at home.
The advantage of the vertical sewing shuttle is that it is easy to adjust this or that sewing conditions fabrics. The interaction of the spout and the needle is quite simple and intuitive to regulate. This is a type of hook of professional use. It interacts with the needle very accurately, is reliable, vibration-free and allows the machine to work well at high speeds.
Lecture Classification of sewing machines. The main working elements of the sewing machine. Sewing machine parts.
Sewing machines are very diverse in appearance, design, and kinematics. Depending on the nature of the thread weave in the stitching, they are subdivided into shuttle and chain weave machines.
The following groups of machines are distinguished by their purpose:
Fix hook position in delta mm902 sewing machine
To indicate sewing machines operates a historically established system of simple serial numbers, somewhat modified in recent years. According to the factory classification sewing machines are divided into classes, variants and modifications. Each manufacturer established its own designation of classes, assigning each newly mastered machine another serial number. If variations (changes or additions of new mechanisms) were developed on the basis of this machine, they were designated by letters, for example, machines 1, 2, 22-A, 22-B, 22-B, 26, 26-A, 51, 51-A cl. The Podolsk Mechanical Plant named after V.I. Vernadsky. М.И. Kalinin (PMZ) of production association “Podolskshveymash”. Since 1968, the Orsha Light Machine-Building Plant of the Promshveymash Production Association has designated its machines the same way. It was decided to retain the designations of formerly manufactured machines and assign to versions of these machines a designation consisting of a machine class number with sequential number beginning with numeral 2.
Orsha Light Machine-Building Plant of Promshveymash Production Association used a similar designation for its machines: machine 97-A cl straight-stitching shuttle weave; 297 кl with lower material seating; 397-M cl with a knife for cutting off parts; 597-M cl with deviating needle; 697 cl with differential displacement of materials, etc. д. Rostov-on-Don plant “Legmash” Production Association “Promshveymash” produces sewing machines and depending on the nature of the work and purpose classifies them by introducing letters and numbers (eg, machines 408-M, 408-AM, 508-M, 1208-A cl. etc. д.).
Place and Sew Hooks and Eyes Correctly
Despite the fact that the numerical and alphabetical designations of sewing machines are abstract, the designation of classes began to reflect the basic provisions of the so-called basic and family principle of sewing equipment, according to which on the basis of basic machine designs are developed their versions and modifications. Modification. adaptation of a basic sewing machine to perform a certain operation without making design changes. An example of a modification is the machine 852-1×10 with a distance between stitches of 10 mm: basic machine 852×5 cl. PMZ has a distance between the stitches of 5 mm.
Domestic sewing enterprises use equipment made by machine-building associations of foreign countries. Czechoslovak association “Minerva” produces industrial machines that perform zigzag stitching; Hungarian foreign trade enterprise exports various sewing machines; association “Textima” (GDR) produces industrial and domestic sewing machines with a shuttle and chain weave. Large shipments of sewing equipment to our country is a Japanese company / Juki “.
How to disassemble a Janome sewing machine
Disassemble modern sewing machines, I do not recommend. There is nothing complicated about it, but only for someone who knows how to do it right. In any other case, all the time there is a desire to use a nailer. Well, like all the screws unscrewed, but the body does not detach. Be cautious, you can easily break not only the attachment housing, but also the desired part of the sewing machine.
For each machine uses its own options for fixing the halves of the body. First you need to carefully examine them, to discover. For example, a few pieces may be under the front cover, near the thread tensioner, shuttle mechanism (remove the needle plate). Further, some are “hidden” under plugs, which can easily be removed with a knife blade. What else can be advised. Well, for example, for this model Dzhanome do not need to remove the levers switch types of stitches. By the way, don’t forget about the reverse lever when you put the case back together. In general, for a non-specialist it will be much more difficult not to disassemble it, and assemble, take it into account. Mark where and which screw was used. And if you do not have any “extra” screws, then the test of care you have sewn 5 points.
If the stitch begins to loop, rings form, then the thread is not threaded correctly. There is no or very little tension. Check if the thread guide is working correctly. Bad stitching can also be due to wrong needle position or wrong fabric. If the needle does not enter the hook, it will not form a loop. The needle must be lowered.
Looping stitch can be due to a faulty spring, which is responsible for the tension. To check it you need to lift the presser foot and pull the string. Then lower the presser foot and pull again. You need to do this several times. If there is no tension, it means that the tensioner spring is not working properly. Too much tension is also bad. If the fabric gathers, it’s the shuttle, you need to adjust the tension and there or just reduce the stitch pitch. Thin fabrics are more susceptible to this problem.
If threads of different colors are used, they must be the same thickness or the lower thread is slightly thinner, but not vice versa. Otherwise there are stitching problems. A damaged bobbin or hook can also prevent thread from coming out freely. Here only a repairman can help.
In general, sewing machines Singer has proven over time its quality and ease of maintenance. Most antique models have been running for years, or are still running after repairs. Modern models are easy to operate, and even threading is easy.
Threading and winding your Singer 7105 is presented below.
Position of the hook nose relative to the eye of the needle
Lower the sewing needle to its lowest position and raise it slightly upwards, about 1.8 to 2.0 mm. Thread a white thread through the eye of the needle if that is more comfortable for you to adjust the position of the hook nose in relation to the eye of the needle. Hold the needle with one hand (the flywheel), and the second hand rotate the axis shuttle (left, right), so that the hook hook nose was set a little higher ear needle, about 1.5 mm. This is the average and relative value. Sewing machines with a zigzag stitch needs to be adjusted on the left and right needle. But for straight sewing machines, or in our case (zigzag machine) as a starting point (the setting of a straight stitch). 1.5 mm is a good value.
Singer sewing machine. How to correctly thread.
Friends and acquaintances keep throwing up interesting questions. Here comes another question, how to correctly insert the thread into an old Singer machine. As always on the Web has found a lot of interesting tips, and the correct way (again) has always been found in the Western expanses (I myself would not be very in this case). But in order to save the psyche of young girls, who are now almost not taught at school, it is better to show clearly without unnecessary words.
Filling the bobbin: we insert the bobbin inside, the thread goes down on the bend indicated in the photo
dragging the thread up until it clicks (thread under the clamp, you can see it in the photo)
To get to work on any type of sewing machine, you first need to make basic settings. The most basic is threading. Beginners seamstresses at first times it is very difficult to make this manipulation due to lack of knowledge of the mechanism of the device. To carry out all the steps correctly, you need to know the principle of how to tuck the thread into the sewing machine correctly and without disrupting the device.
How to tune an old sewing machine “Podolsk”?
The peculiarity of this sewing machine is that it can be used to sew thick and dense fabrics, such as denim. The machine is easy enough to use, but it is necessary to observe simple rules that will prolong the operating life of the design:
- According to the instructions, the handwheel of the machine should rotate only in the direction “on itself” (the direction of the handle. from the working person). Do not turn the handwheel away from you because the thread could become tangled in the hook.
- If the machine is not running, the presser foot must be raised.
- Do not run the machine without placing fabric under the presser foot, as the teeth of the device which advances the fabric could become dull.
- Do not pull or push the fabric during operation. Needle could break or bend. The machine advances the fabric by itself.
- Do not forget to close the front plate tightly over the hook when operating it.
How to wind the thread on the bobbin?
Podolsk” machine is equipped with a special winding device located at the back of the machine, near the handwheel.
Important! The rewinder works in conjunction with the lower thread tensioner, which is placed in the right-hand corner of the platform. The sewing mechanism must not be running during the thread winding process.
How to set up an old manual sewing machine of this model:
- The first thing to do is to disengage the handwheel, so it can not start the movement of the machine. To do this turn the friction screw located in the center of the handwheel towards yourself.
- Install the bobbin on the bobbin winder.
- Slide the thread spool onto the spool pin.
- Pass the thread from the spool under the idler washer and then up to the bobbin.
- Push the winder frame down so that the rim of the pulley is in contact with the handwheel.
- Hold the loose end of the thread until enough turns are wound to secure the thread. Then tear off the protruding end of the thread.
Important! The winding is tight and even when it is correctly wound.
Threading the bobbin into the bobbin case:
- Holding the bobbin with your right hand, slide it into the bobbin case. In doing so, the oblique slit in the cap should be at the top.
- Then pull the thread through the slit to the tension spring, then into the slit at the very end of the spring.
- Place the cap in the machine, bring the loose end of the thread out, and close the shuttle.
How to install the needle correctly?
The needle is installed with the needle bar in the highest position.
Important! The needle must be installed correctly. Otherwise, the stitching will be missed. The flat part of the needle bulb points to the left and the long groove on the blade points to the right.
Threading the upper thread:
- Turn the handwheel towards yourself and bring the thread tensioning lever with the hole to its highest position.
- Install the spool on the rod and pull the thread to the eye of the needle.
Important! Threading from right to left into the eye of the needle.
Prepare the machine for sewing
How to adjust a manual sewing machine, figured out. Now let’s get ready to sew:
- First of all, pull the bottom thread out. To do so, turn the handwheel of the machine until the needle is lowered, taking the hook thread, and then raised again to the upper position.
- Then pull both threads to the back and put them under the presser foot.
- Lower the presser foot onto the fabric.
- The machine is ready to work.
Advantages of a horizontal hook
What are the advantages and disadvantages of the horizontal hook?? Which shuttle is better?? The advantages of the horizontal hook are obvious. First, the soft glide of the thread through the plastic hook also ensures that the machine runs quietly. Secondly, the quality of stitching these machines is an order of magnitude higher than machines with a swing hook. Thirdly, easy threading and visual control. And finally, a very precise adjustment of the interaction between the hook and needle, which provides a reliable looping and provides an opportunity to sew any “capricious” fabrics such as knitwear, stretch, etc. But what to choose a sewing machine, what type of hook. you decide, because in addition to quality and convenience there are other parameters, including financial opportunities.
