Description

Technical Field

[0001] The invention relates to the technical field of sewing processing, in particular to a one-time formed double-layer folding edge pull tube for home textile products. Background Art

[0002] At present, many home textile products such as quilt covers, pillow cases, and cushions need to be sewed with buttons and buttonholes at the opening. The exposed buttons and buttonholes will affect the overall aesthetics, and the direct contact of buttons with the skin will affect comfort. Therefore, it is necessary to make double-layer folding at the opening of quilt covers, pillow cases, and cushions, with the upper layer as the covering layer for buttons or buttonholes, and the lower layer as the buttoning or eyelet layer. There are usually the following methods to make double-layer folding: Place the front side of a cutting piece with the same width as the surface fabric facing upwards, fold one side from outside to inside to the width required for cutting buttonholes or sewing buttons, then place the front side of the surface fabric facing upwards, align one side with the edge of the folded layer, and press it on the cutting piece, then fold the other side of the cutting piece from outside to inside to the width of the seam allowance, then fold another side to the width required for cutting buttonholes or sewing buttons, press the seam allowance on the sewing part of the surface fabric, and tie sewing lines along the seam edges, thus forming two double-layer edges on the surface fabric, with the upper layer being the covering layer, and buttons or buttonholes being sewn on the lower layer; then place the front side of the inner fabric facing upwards, sew three sides to the surface fabric, and sew buttons or buttonholes on the folded edge of the opening.

[0003] Place the front side of a cutting piece with the same width as the surface fabric facing upwards, and fold one side of the cutting piece three times from outside to inside, from inside to outside, and then from outside to inside in succession according to the width required for cutting buttonholes or sewing buttons. Then, place the front side of the surface fabric facing upwards, align one side with the edge of the folded layer, press it on the sewing part of the cutting piece, and tie the sewing thread along the seam edge to form two double-layer edges on the surface fabric, with the upper layer being the covering layer, and buttons or buttonholes being sewn on the lower layer. Then, place the front side of the inner fabric facing upwards, sew the three sides to the surface fabric, and sew buttons or buttonholes on the open folded edges.

[0004] Turn the front side of the surface fabric upwards, fold one side of the surface fabric from outside to inside according to the width required for cutting buttonholes or sewing buttons, and then fold it again from outside to inside according to twice the width required for cutting buttonholes or sewing buttons, and tie the sewing line along the seam edge from the sewing of the first folded edge to form two double edges on the surface fabric, with the upper layer being the covering layer, and buttons or buttonholes being sewn on the lower layer; then turn the front side of the inner fabric upwards, sew the three sides to the upper fabric, and sew buttons or buttonholes on the open folded edge.

[0005] When sewing by the above three methods, the size of the seam head is difficult to control, the lower piece of the double-layer folded edge is easy to be uncovered, and exposed to the front to affect the appearance. The quality of the sewn product does not meet the standard requirements, fabrics and accessories are wasted, and work efficiency and overall appearance are affected. Summary of the invention

[0006] In order to overcome the shortcomings of the existing production technology, the invention aims to provide a one-time formed double-layer folding edge pull tube for home textile products to solve the problem that buttons and buttonholes of home textile products are directly exposed and affect the overall appearance.

[0007] To achieve the above-mentioned purpose of the invention, the double-layer folding pull cylinder of the present invention includes a base, a swing arm, a connector and a pull cylinder. The pull cylinder is a double-layer folding channel formed by bending and winding an iron plate from bottom to top and from outside to inside. The first layer channel of the double-layer folding channel is connected to the second layer channel.

[0008] Preferably, the first layer of channels is formed by the fifth layer of plate being connected in sequence through the first folded edge, the first layer of plate, the second folded edge, the fourth layer of plate, the third folded edge, the second layer of plate, and the third folded edge arc transition.

[0009] Preferably, the second layer channel is formed by a third layer plate connected to a third folded edge and a fourth folded edge arc transitionally connected, and the end of the fourth folded edge is welded to the fourth layer plate.

[0010] Preferably, the base is connected to the swing arm via a first screw, and the connector is connected to the swing arm via a second screw; the hole for fixing the base to the sewing machine table is a waist-shaped hole; the connection hole between the connector and the swing arm is a waist-shaped hole, and the base is fixedly connected to the sewing machine table; the connection between the connector and the pull cylinder has an arc structure for enhancing the strength of the connector.

[0011] Preferably, the base, swing arm, connector and pull tube are made of stainless steel metal material.

[0012] Preferably, the distance between the first folded edge and the second folded edge of the first layer channel is 10 cm-20 cm.

[0013] Preferably, the distance between the fourth folded edge of the second layer channel and the third folded edge of the first layer channel is 5 cm-10 cm.

[0014] Compared with the prior art, the present invention can better solve the problems of inconsistent width of the double-layer folded edge, the upper piece not being able to cover the lower piece, and the waste of fabric and sewing thread. The product has beautiful appearance and can effectively avoid the disadvantage of buttons directly contacting the skin and affecting comfort. It has a simple structure, convenient and fast operation, stable quality, and is easy to master. It can greatly improve work efficiency and reduce production costs. BRIEF DESCRIPTION OF THE DRAWINGS
