Problems solved by technology
At present, there are relatively many curve sewing equipment based on the template machine style on the market, but most of the mechanisms are complex in structure, and the installation and disassembly of the mechanisms are extremely inconvenient.
In addition, the structure of the curved sewing equipment used in general lockstitch sewing machines is relatively complicated and expensive, and is not suitable for large-scale production and popularization.

The invention provides a curve sewing device. The curve sewing device comprises a fixed base, a fabric detection sensor installed on the fixed base and a material pressing piece which is installed onthe fixed base and is rotatable; in the fabric feeding direction of forward fabric feeding of a fabric feeding mechanism in a sewing machine, the fabric detection sensor is located on the back side ofa machine needle in the sewing machine; in the direction perpendicular to the fabric feeding direction of fabric feeding mechanism, the fabric detection sensor is located the side, towards a machinetail, of the machine needle in the sewing machine; when the fabric detection sensor detects that a fabric exists in the lower portion of the fabric detection sensor, the material pressing piece does not rotate; when the fabric detection sensor detects that the fabric does not exist in the lower portion of the fabric detection sensor, the material pressing piece presses and attaches the fabric to rotate in the direction close to the fabric detection sensor till the fabric detection sensor detects that the fabric exists in the lower portion of the fabric detection sensor. According to the curvesewing device, through mutual matching of the material pressing piece and the fabric detection sensor, various curves can be sewed, and sewing of various curve edges on the fabric is achieved; the curve sewing device is simple in structure, low in cost and suitable for large-scale production and application and popularization.
Description
technical field [0001] The invention relates to a curve sewing device. [0002] The present invention also relates to a sewing machine comprising the above-mentioned curve sewing device. Background technique [0003] The garment sewing process is mainly divided into two types: the straight line sewing process for straight edge sewing and the curved sewing process for curved edge sewing. Each piece of clothing uses these two sewing processes to complete the splicing of fabrics. Since the curved stitches formed by the curved sewing process directly affect the overall aesthetics and uniformity of the garment, the technical requirements for the curved sewing process are relatively high, and thus the requirements for the curved sewing workers are also relatively strict. In addition, in the garment sewing process, the curve sewing process is relatively common, so the automation demand of the curve sewing process is relatively large. At present, there are relatively many curve se...
