Embodiment Construction

[0010] The present invention will be further described below in conjunction with accompanying drawing.

[0011] refer to figure 1 and figure 2 , a specific technical scheme of an automatic edge curler for a sewing machine is: it includes an initial section 1, a gradual transition section 2 and a forming section 3 that are sequentially connected and provided with baffles 4 on both sides; the initial section 1 is rectangular, and its width Greater than or equal to the width of the material when it is not crimped; the gradient section 2 is trapezoidal, and its width is gradually reduced to the predetermined width after the material is crimped along the direction of material introduction; the forming section 3 is rectangular, and its width is greater than or equal to that of the material Width after hemming.

[0012] Further, the baffles 4 on both sides are U-shaped structures, and the openings 5 ​​face to the corresponding other side.

[0013] Further, the baffles 4 on both s...

Abstract

The invention discloses an automatic hemmer for a sewing machine. The automatic hemmer comprises an initial section, a transition section and a forming section which are sequentially linked and provided with baffles on two sides, wherein the initial section is rectangular and is greater than or equal to a material which is not hemmed in width, the transition section is trapezoid, the width of the transition section is gradually decreased to the predetermined width of the hemmed material in the advancing direction material guide, the forming section is rectangular, and the width of the forming section is greater than or equal to the width of the hemmed material. The automatic hemmer can completely and automatically hem a fabric according to a required shape when a hem is sewn, then conveys the fabric to the sewing machine for sewing, improves the working efficiency and meanwhile improves the product quality.

Description

technical field [0001] The invention relates to the field of textile machinery and equipment, in particular to an automatic curling device for a sewing machine that can assist a sewing machine to automatically curl fabrics when sewing curls. Background technique [0002] In the existing garment processing process, when splicing, due to the joint sewing between two pieces of fabric, the edge of the fabric is often redundant. For the overall quality of the garment, the edge of the fabric needs to be trimmed and processed later. Remove the burrs and prick the edges. When using a sewing machine to sew the hemming of clothes, people generally adopt manual work to first hem the cloth, and then send it into the sewing machine for sewing. The sewing efficiency of this method is very low, and the quality of the finished products is also uneven, which is not troublesome in this processing method, which reduces the efficiency of garment processing. Contents of the invention [0003...
