Abstract

Usage: in the clothing industry. SUMMARY OF THE INVENTION: a method for manufacturing waffle puffs for clothes includes the steps of pre-forming a series of parallel folds of fabric and subsequently pinning the folds apart from each other in a checkerboard pattern along the length of the fabric web to provide a three-dimensional shape. The formation of a series of parallel folds and their bonding is carried out in the working area of the needle of the sewing machine. The needle assembly is additionally provided with three stops which are attached to the platform of the machine, wherein the adjustment of the depth of the folds during the forming process is carried out by the first stop, which is placed behind the needle. The distance between the fastening points is controlled by the side, left and right stops. 3 ill.

Description

The invention relates to the clothing and knitwear industry and can be used as a decoration for clothing and other sewing and knitwear.

The purpose of the invention is to increase labor productivity in the manufacture of waffle puffs by mechanizing the process of pin bonding adjacent folds and thereby producing waffle puffs.

This goal is achieved by the fact that the receipt of structural and finishing elements of clothing (waffle puffs) in the form of sections of parts of various shapes, tightened by assemblies, by pointwise connecting sections of the fabric cloth located at a distance from each other, in a checkerboard pattern, the fabric parts are folded double the face inward, thus forming a fold, and fed folded into the working area of the sewing machine, capable of fastening parts close to the point, for example, a semiautomatic device of class 95 PMZ nVi. Kalinin, until it stops, is fixed on the needle plate, with the possibility of adjusting the position on which landmarks are installed that determine the distance between the fastening points of the fabric, after installing the folded part on the stop and landmarks, the semiautomatic device is turned on and a connection is made that is close to point, then move the part a step along the landmarks and thus the fold is fixed with individual points with a given step and the distance

from the edge of the bend, after which, next to the first one, the second fold is laid and fastened similarly to the first with a shift of the fastening points by half a step, subsequent folds are laid and fastened in the same way, shifting the fastening point by half a step relative to the previous ones, while the folds with a given step by workpieces are pleated by one of the known methods.

Figure 1 shows one of the possible options for waffle puffs; Fig. 2 is a flowchart of operations; in Fig.Z - the working area of the semi-automatic 95 class PMZ them. Kalinin with emphasis and landmarks,

The manufacture of waffle puffs is carried out according to the proposed method in the following sequence,

The canvas parts are folded twice in the face inward or pleated with a predetermined step on 1 pleating machine. The fabric is fed into the working area of the sewing semiautomatic device until it stops 1 (Fig. 3) and by pressing the pedal a semiautomatic device is turned on which makes a connection close to a point one. Move the part to the right until the connection point coincides with the spruce edge of landmark 2. Connect at the next point, etc. After fixing the folds along the length along the lengths, the next fold is fed into the working area, as can be seen from FIG. The second fold is point bonded by moving the part to the left until the connection point coincides with the right edge of landmark 3, placing the first bonding point between the two extreme points of the previous fold (Fig. 2). The following folds are connected as many as are required in design.

Before performing the operation, the semiautomatic device is adjusted to sew stitches with a minimum distance between injections,

The button holder is replaced with a presser foot 4, for example as shown in Fig. 3, position 4.

The position of the stop 1 is adjusted with the screws 5 loosened, and the guides 2 and 3 with the loosened screws 6 and 7, respectively.

When performing symmetrical buffs, the distance from the needle axis to landmarks 2 and 3 should be the same; for different distances from the needle axis to landmarks 2 and 3, the buffers will not be symmetrical. When

it is advisable to apply fold places to the manual folding of wrinkles on the parts, which can be noted with the help of scattering, when folding the folds into the working area of the semiautomatic device, the fold line

emphasis 1, and the previous fold is brought to the limiter 8, in this case, high-quality execution of the buffer will be ensured.

The proposed method of manufacturing waffle puffs allows to mechanize

a technological process that will ensure the growth of labor productivity while ensuring high quality, since in this case it is more difficult to obtain quality manually than in a mechanized way.

Claims (1)

SUMMARY OF THE INVENTION A method of manufacturing waffle puffs for clothes, which consists in pre-forming a series of parallel folds of fabric and subsequent point fastening the folds at a distance from each other along their width in a checkerboard pattern along the length of the fabric web to provide a three-dimensional shape, characterized in that, in order to increase productivity ™ labor while improving the quality of finishing elements, the formation of a series of parallel folds and their fastening is carried out in the working area of the needle of the sewing machine1, for which the unit the needles are additionally provided with three stops which are attached to the platform of the machine, wherein the adjustment of the depth of folds during the formation is carried out by the first stop, which is placed behind the needle, and the adjustment of the distance between the fastening points is carried out by the lateral left and right stops.
