Description

(54) METHOD FOR PRELIMINARY CONNECTION OF DETAILS

SEWING PRODUCTS FROM SYNTHETIC MATERIAL

WITH FIBER WARMING GASKET AND SEWING

MACHINE FOR ITS IMPLEMENTATION

the main shaft is the needle bar with a needle, the engine of the material and the foot, the needle has notches located on the sides of the blade and directed to the opposite side to the needle's tip.

The drawing shows a diagram of a sewing machine for the implementation of the proposed method.

The method of pre-connecting the parts of the garments is as follows.

Pre-cut details of the top, for example, sleeves, shelves, backs, jackets made of nylon fabric, apply heat insulation to the corresponding parts: gaskets, after which the material package is preliminarily joined by creating a stitch with a rough surface on the top parts by removing fibers from the insulation. gaskets on the front side of the top part and thus drying, the formation of a connecting seam, the width of which does not exceed the width of the connecting seam, which connect the package of parts one with each other, is established m, for example a shelf with a back and with the sleeves in the preparation of garments. At the same time, when the package of parts is preliminarily joined (shelf or back), the equipment is carried out along the edge of the part. A sewing machine for carrying out the method of joining parts of garments with a thermal strip consists of a main shaft 1, a crank 2, a connecting rod 3, a needle bar 4 connected to the crank mechanism by a clamp 5 and a screw 6.

At the end of the needle bar 4, the needle 7 is fastened with the clip 7 of the clip 8.

The needle 7 consists of a bulb 9, a blade 10 and a notch 11 pointed in the direction of the bulb 9 located along the perimeter of the blade of the needle 7.

The machine also has a material advancement mechanism and a material clamping mechanism.

The mechanism of advancement of the material consists of a fabric engine 12, a lever 13 with a fork 14 at one end. The second end of the lever 13 is pivotally connected to the advance shaft 15. Fork 14 covers the roller 16, rigidly mounted on the shaft 17 of the rise.

The propeller shaft 15 is mounted in the machine platform (not shown) with the possibility of oscillating movement through the crank 18, the connecting rod 19, the fork 20 and the eccentric 21 mounted on the main shaft of the device. The lifting shaft 17 is mounted with the possibility of oscillating movement through the crank 22, the connecting rod 23, the eccentric 24 mounted on the main shaft 1.

The clamping mechanism of the fabric consists of a spring-loaded spring 25 of the rod 26, at the end of which a foot 27 is fixed. In addition, the machine is equipped with a knife mechanism (not shown).

The machine works as follows. From the main shaft 1, the rotation is transmitted to the needle crank mechanism and the material advancement mechanism. During operation of the device, the foot 27 presses the material to the engine 12 of the fabric, the needle 7 pierces a layer of materials, and during the return movement the pointed protrusions 11 of the needle 7 capture the fibers of the gasket material of the material package being processed and drag them through the layer of the package.

These fibers are clamped by the threads of the base fabric, and thus the entire package of materials is bonded along the seam line that runs along the contour of the workpiece at a distance from the edge of the part that does not exceed the width of the connecting seam so that the strip warmer warms to the surface , giving this surface a roughness effect and helping to reduce the fit of the fabric when making the connecting seams, at the same time were not visible on the surface of the finished product after connecting the other parts g other.

In order to impart greater strength to the seam of the fastening of the package of materials, two or more can be fastened to the needle bar.

needles with pointed protrusions, and they can be positioned both sequentially and in parallel.

The proposed method of joining the package of materials along the contours of the garment parts will reduce thread consumption, the cost of the edges of the parts, and the insulation material placed on the surface of the top fabric will provide the surface roughness of the top of the product part along the line of subsequent joints, which will improve the quality of performance like these. seams, and the product as a whole. Thus, the use of the proposed method will improve the quality of processing by reducing the cost and planting of the material and obtain savings

threads to connect the details of the top and insulation.

Claims (2)

1. A method of pre-joining parts of garments made of synthetic material with a fibrous insulating pad on a sewing machine by stacking connecting parts one on another to form a bag and forming along the contour of the main part of the connecting seam, the width of which does not exceed the width of the connecting seam parts upon receipt of a garment, characterized in that, in order to improve the quality of the garment, the formation of a connecting seam is carried out by removing fibers warm yushi pads on the front side of the top details. 2.
