Embodiment 1

[0050] A kind of wrapping device, refer to Figure 3-4 As shown, it includes cuboid guide body 3 arranged sequentially along the direction of cloth strip conveying. The guide body 3 is arranged through along the direction of cloth strip conveying. One end has an entrance for cloth strip to enter, and the other end has an entrance for cloth strip to pass through. outlet; the upper and lower inner walls of the guide body 3 are perpendicular to the vertical plane of the elongated cloth strip 1 that is transmitted and are set in conflict with the outer surface of the cloth strip, and the upper and lower inner walls of the guide body 3 As the first flange 31.

[0051] The inside of the guide body 3 is provided with a folding plate 4 that is parallel to the conveying direction of the cloth strips. The folding plate 4 includes two flanges 41 that are arranged up and down. The two flanges 41 are symmetrically arranged in mirror images. 41 includes a straight plate 411 vertically arra...

Embodiment 2

[0058] A sewing process, refer to Figure 6-7 shown, including the following steps:

[0059] A) First, wind the long strip of cloth 1 raw material to be sewn on the unwinding roller 15, and continuously convey the cloth strip to the subsequent device;

[0060] B) a stitching sewing machine 14 is arranged in the path of cloth strip transmission, and after a roll of cloth strips on the unwinding roller 15 is used up, the head end of a new roll of cloth strips can be combined with the previous roll by utilizing sewing sewing machine 14 The end of cloth strip is sewed, thereby can continuously provide cloth strip to follow-up device; Along the conveying path of cloth strip, cloth strip is sent out from sewing sewing machine 14 and hangs on the storage support 16, when sewing sewing machine 14 is sewing, The reserved cloth strips on the storage bracket 16 can continuously provide raw materials for subsequent sewing devices;

[0061] C) Hemming, after the cloth strip is conveyed f...

Abstract

The invention discloses an edge covering device which comprises a guiding body, a forming body and a deforming portion. The guiding body and the forming body are arranged in a through mode, and the deforming portion is communicated with the guiding body and the forming body. A folding plate arranged in the cloth strip conveying direction in parallel is arranged at the end, away from the forming body, inside the guiding body. The inner walls of the folding plate and the guiding body abut against the inner and outer surfaces of the cloth strip and are used for achieving right-angled overturning of rough edges of the cloth strip; the height of the deforming portion is gradually decreased from the guiding body to the forming body to achieve centering overturning of the cloth strip; the forming body is provided with an oppositely-arranged U-shaped portion bent inwards, the inner wall of the U-shaped portion abuts against the outer surface of the cloth strip to achieve inward overturning of the rough edges of the cloth strip. According to the edge covering device and the sewing technology applying the edge covering device, the steps of the sewing technology can be simplified, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of garment sewing, in particular to a hemming device and a sewing process using the hemming device. Background technique [0002] In the production process of making cloth belts, before sewing, the fabric is long and has raw edges on both sides. For the sake of aesthetics, it is necessary to hide the raw edges inside when sewing. The general manufacturing process is: [0003] 1. Fold the cloth strip in half and iron it; [0004] 2. Then sew the raw edges of the folded cloth strips; [0005] 3. After sewing, turn the cloth strips out as a whole, and turn the original inner surface to the outside; [0006] 4. Carry out flat car crimping on the two long sides of the cloth strip respectively. [0007] It can be seen that the process of sewing a belt has many steps and requires high labor intensity. The operation is difficult and inefficient. When the same product is produced in large quantities, manual opera...
