How to fill a thread in a sewing machine and in an overlock?

Usually, household sewing equipment is quite easy to manage. But a common man who uses a sewing machine once a year to update the supplies of kitchen towels or pillow cases, it is difficult to remember the basic rules of threading or winding the bobbin. However, a few minutes to study the operation manual - and you can start working. But how to fill a thread in a sewing machine, if this document is lost? Or how to cope with a three-or four-in-one overlock, if the filling scheme is completely forgotten? Are there any basic rules? This is exactly what will be discussed later. So, how do I thread the sewing machine?

It is worth noting that for sewing it will be necessary to make the top and bottom refueling, so it is advisable to consider both processes in more detail and understand the principle.

Basic rules for top threading in the sewing machine

Of course, all models have their differences, but the principle of operation of these units is the same, so you can identify the main rules:

• The thread must necessarily be on the spool, which is installed on a special pin. Depending on the model of the unit it can be a pin on the top panel of the machine body or a specially equipped hull for the skein located near the handle for carrying the machine.
• Then the thread must pass through the holder, providing the necessary tension and area of the tension regulator.
• The next element is the lift lever of the thread. If it is wrong to pass a thread through it, it will get tangled on the fabric and break off.
• Filling the thread into the sewing machine involves its passage through special clamps and hooks, which provide the necessary tension and prevent tangling. Therefore, the thread, going down to the needle from the feed lever, must pass through the hooks on the holder.
• When entering the needle hole, you need to make sure that the thread does not wrap around it, and there are no corners on the edge that make it difficult to pass. Some higher-end models have a special device for inserting a thread into the sewing machine. However, without it, it is quite simple.

Rules for filling the bottom thread of the sewing machine

The principle of laying a machine stitch is that two threads are involved in the work, which are intertwined at the puncture site. But on how to fill the thread in the machine, all of her work depends. After all, more faults are reduced to incorrect operation. Therefore, for correct operation of the unit, the correct upper and lower threading of the thread in the sewing machine is required. The whole process of installing the bottom thread can be divided into two stages:

• Bobbin winding;
• Setting the thread in the shuttle.

Almost all new models have special indicators on the body for winding the bobbin (a small coil with a lower thread), but if they are not available for any reason, you should study the body of the unit. It should have a small pin with a switch and a winding stop in the form of a disc on the pin.

Next it remains to understand how to thread the bobbin. To do this, the coil is mounted on the main pin (or in a box), is passed through the tension holder device, fastened to the coil by several turns, switched to the winding mode and the unit is started. Usually this mode is activated by moving the pin to the bobbin to the side.

Then you need to insert the thread into the sewing machine. And here it is necessary to determine the type of shuttle, on which further actions depend.

Features of the bobbin installation in the vertical shuttle

The vertical shuttle is characterized primarily by its arrangement and arrangement. In it, as a rule, there is a removable housing, where the bobbin is inserted. The free edge of the thread should be placed in a special hole under the pressure plate. This is done quite simply, just put the thread in the slot and pull it. Next, the body is inserted into the shuttle device until it clicks. In this case, the so-called finger should look up, and hold the part behind a special hold-down handle. When the lower thread is in place, the needle is lowered and both edges of the threads (top and bottom) are brought to the working surface. Perhaps, this is all you need to know about how to thread in a sewing machine.

Features of the bobbin installation in the horizontal shuttle

The process of filling the lower thread of the machine always begins with winding it onto the bobbin. Setting the thread in the horizontal shuttle is more primitive, as is its device as a whole. Here, the bobbin is placed in a special hole under the lid under the working needle. Then hold the free edge of the thread by pulling it into special slits. Then, lower the needle and pull out both edges of the working threads.

The quality of the stitch depends on how to fill the thread in the sewing machine. Ideally, the yarns should be intertwined in the puncture of the fabric, but if one of the sides forms loops, make sure that the tension is adjusted. If the problem persists, all the elements of the refueling path must be checked once more.

Features of threading the thread in the overlock

All leading manufacturers of sewing equipment, taking care of the user, put marking marks directly on the body to mark the working threads and paint hooks. For each serial number its color is red, green, blue or yellow. But how to fill the thread in the overlock without pointers?

Here you also need to understand the basic principle of the unit. For example, in a four-thread overlock, the first two threads are for needles, the others for upper and lower loopers. So, how do I thread a thread in an overlock with two needles?

Needle refilling

All coils should be installed on special pins and thread through holes on a special lifting rack. Afterwards, on the upper part of the body, thread into the holes in front of the clamping devices for tension, designed to prevent tangling of the threads during the operation of the unit. Further, for each of them, there is a separate path from the tension regulator to the exit to the needle or looper. In a two-needle overlock, both strands are connected in the elevation lever zone and pass along all the hooks together, separating only at the entrance to the needle. The thread from the first coil on the pin goes to the first needle, the second to the other. Next, you need to understand the dressing loopers, which, in fact, and sweep the edge of products.

Thread loopers

The third pin is the upper looper. The thread coming down from the clamping device through a special groove must be brought out to the panel with the holders (hooks). Clinging to one of them, it is led to the upper looper. After again, fix in the holder and spend in the hole of the big hook.

The fourth pin is the lower looper. The thread is also lowered to the panel with the holder, fastened to it, after scrolling the handwheel of the overlock so as to open the looper post, hook the thread for two hooks and pass into the looper hole. After press on the presser foot to start work. It is necessary to make the first few stitches flywheel, and then you can add speed.

If you know the main points of sewing devices, none of the models will cause difficulties with the question of how to thread the sewing machine and overlock. Everything is simple enough. The main thing - just to study all the elements of the unit and carefully treat the refueling process.
