Abstract

FIELD: sewing industry, in particular, sewing of decorations, preferably beads, to clothing parts.

SUBSTANCE: method involves placing beads onto fabric with their flat surface; providing first pricking by directing needle into bead hole; moving fabric in direction opposite to stitching line by value equal to bead height and providing second pricking by directing needle through fabric, with needle thread turning bead in such a manner that bead is placed with its spherical surface onto surface of fabric; moving fabric in direction coinciding with direction of stitching by value equal to total of diameter and height of bead; providing third prickling similar to first prickling, with needle thread sliding from sewn bead.

EFFECT: increased efficiency, reduced labor intensity, increased strength and provision for producing of line meeting aesthetic demands.

Description

The invention relates to the clothing industry, namely to sewing jewelry, mainly beads, to elements of clothing.

A known method of sewing beads manually / 1, p. 357 /, in which in the initial stage, the performer pierces the material with a needle from the bottom up; after the needle tip of the material exits, the beads 4 are manually strung onto the needle, then the performer pierces the material with the needle from top to bottom and the thread stitch secures the beads to the material; then the process is repeated from the initial stage.

The disadvantage of this method is the low productivity and high complexity of the operation.

There is also a method of sewing buttons on sewing machines, in which the holes of the sewn buttons are located perpendicular to the plane of the fabric / 2, s.216 /.

However, these semiautomatic devices are not acceptable for sewing beads, since when using them it is impossible to achieve the desired result. The beads should be sewn so that its spherical surface touches the fabric.

Closest to the invention is a method of sewing beads on a sewing machine, known from WO 93/00468, 01/07/1993. Sewing is performed by successive thread stitches connecting the beads to the fabric, while the beads are laid on the fabric with a flat surface, the first needle injection is made into the bead hole and the fabric is pierced, before the second needle injection the fabric is moved towards the operator by an amount equal to the height of the beads, the second injection the needles are made into the fabric, before the third injection of the needle, the fabric is moved away from the operator by an amount equal to the sum of the diameter and height of the beads, the third needle injection is made into the bead hole and the fabric is pierced.

However, this method does not solve the problem of increasing the strength of sewing beads to the fabric and does not create a bead stitch of a more aesthetic appearance due to the lack of contrast on the fabric.

The objective of the invention is to increase productivity, reduce labor intensity, increase strength and give the bead line an aesthetic appearance.

The technical result is achieved by the fact that in the method of sewing beads on a sewing machine, performed by sequential thread stitches connecting the beads to the fabric, in which the beads are laid on the fabric with a flat surface, the first needle injection is made into the bead hole and the fabric is pierced, before the second needle injection the fabric is moved in the direction of the operator by an amount equal to the height of the beads, the second injection of the needle is performed into the fabric, before the third injection of the needle, the fabric is moved away from the operator by an amount equal to the sum of the diameter and the height of the beads, the third needle injection is made into the hole of the beads and the fabric is pierced, according to the invention, before the fourth injection, the fabric is moved towards the operator by an amount equal to the height of the beads, the fourth needle injection is made into the fabric between the sewn and sewn beads, before the fifth injection of the needle, the fabric is moved in the direction from the operator by an amount equal to the sum of the diameter and height of the beads, the fifth needle prick corresponds to the first.

The result of using the proposed method is to obtain a bead stitch of an aesthetic appearance - sewn beads touches the fabric with a spherical surface, and the needle thread, sliding off the spherical surface of the beads when sewing and laying on top of the fabric, emphasizes the line and gives it contrast.

The invention is illustrated by drawings, where

figure 1 and figure 2 is a stepwise depicted method of sewing beads on a universal sewing machine;

figure 3 - arrangement of sewn beads on the fabric;

figure 4 - photo of a fragment of the finished product.

The method is as follows (figure 1):

The fabric 1 is fixed, the beads 2 are laid flat on the fabric, the axis of the hole of the beads coincides with the axis of the needle 3 (Fig. 1, a). The needle 3 enters the hole of the beads 2 and into the fabric 1, the needle thread 4 forms a plexus with the shuttle thread (Fig. 1, b)). The needle 3 comes out of the fabric 1 and the holes of the beads 2 (Fig. 1, c)). The fabric 1 is fed towards the operator by an amount S equal to the height H of the beads 2, the needle drops down, and its thread 4 turns the beads 2 from the initial position to the desired one, in which the beads 2 touch the fabric 1 with a spherical surface (Fig. 1, d) )

The needle 3 enters the fabric 1, and its thread 4 with the shuttle thread forms a plexus; beads 2 by tension of the needle thread 4 is fixed in the desired position (figure 1, d)). The needle 3 leaves the fabric 1. The fabric 1 is supplied from the operator by an amount S 'equal to the sum of the height H and the diameter D of the beads (Fig. 1, e)). The needle thread 4 slides from the sewn bead 2 and rests on the fabric 1. Between the beads 2 and the beads 2a, the distance is maintained for further turning the right bead 2a with the needle thread 4 from the transport position to the desired position (Fig. 2, a)) and the needle 3 is punctured between the beads (figure 2, d)).

The fabric 1 is fixed, the beads 2a are laid flat on the fabric 1, the axis of the hole of the beads 2a coincides with the axis of the needle 3 (Fig.2, a)). The needle 3 enters the hole of the beads 2a and into the fabric 1, the needle thread 4 forms with the shuttle plexus (Fig.2, b)). The needle 3 comes out of the fabric 1 and the hole of the beads 2A (figure 2, c)). The fabric 1 is fed towards the operator by an amount S equal to the height H of the beads, the needle 3 drops down between the sewn beads 2 and the sewn beads 2a, and its thread 4 turns the beads 2a from the initial position to the desired position, in which the beads 2a touch the fabric 1 with a spherical surface (figure 2, g)).

The needle 3 enters the fabric 1 between the sewn beads 2 and the sewn beads 2a, and its thread 4 with the shuttle thread forms a plexus; beads 2a by tension of the needle thread 4 is fixed in the desired position (figure 2, d)). The needle 3 leaves the fabric 1. The fabric 1 is supplied from the operator by an amount S 'equal to the sum of the height H and the diameter D of the beads (Fig. 2, e)). Coincides with figure 1, a) while the needle thread 4 slides from the sewn beads 2A and rests on the fabric 1.

Next, sewing is continued in the above sequence. After completion of the specified drawing, the line is fixed. On the left side, the threads do not overlap, but lie one on top of the other.

A diagram of the implementation of the method is shown in figure 3.

The method of sewing beads on a universal sewing machine was tested in the training laboratory at the department "Light industry machines". On a sewing machine with manual feeding of beads and changing the supply of fabric after each injection of the needle, by manually acting on the lever to change the length of the stitch, the beads were sewn to the fabric. A fragment of the sewing of beads is shown in figure 4. When automating the supply of beads under the needle, the speed of sewing it on a universal sewing machine increases by 10 times, compared with manual sewing.

The proposed method is advisable to use at the enterprises of the clothing industry in the design of clothing items.
