"x" stitching method for mounting uppers by means of the string-lasting system

An X stitching method for mounting uppers using a string lasting system, which includes the application to an upper (1), for full assembly of shoes, using string traction (2) as the element responsible for closing the edges of this upper (1), against a mold (3), and which may overlock, zigzag or stitching machines in general, such as programmable automatic sewing machines, CNC, with a Cartesian coordinate table, with or without the third or fourth integral axle, or even manually, characterized by a method with X stitching, using a sewing machine or manual sewing, applied to an upper (1), for the assembly of shoes, so as to generate a cross vector tractioning, resulting in full, proportional, symmetric and simultaneous fitting, of the upper (1), to the body and sole of the mold (3), in the region of the insole, completely covering the three different areas of assembly of shoes, i.e. the toe, the area in the region of the shank and the rear;

• the stitching order of the “X” methodology can be reversed, or mirrored, or even initiated or terminated at other points of the circuit, depending on the sewing equipment available, or the operator's preference.
