step one, before starting up and running, setting a running starting point of a wire arranging device (a braiding machine component) and the width of a take-up pulley A on a human-computer interface, and after the setting is finished, starting the braiding machine.

And step two, when the wire arranging device of the braiding machine runs to a position 10mm away from the edge A of the take-up pulley, the moving cylinder 3 drives the reversing executing mechanism 2 to integrally move to the position of the edge part on the inner side of the take-up pulley 3, and after the PLC counts for 2S, the pressing cylinder 22 presses down, and at the moment, the wire arranging device continuously keeps the original wire arranging speed unchanged.
