なし得るようにすることがその目的である。DETAILED DESCRIPTION OF THE INVENTION When automatically cutting decorative threads, the present invention provides a method for automatically cutting decorative stitching threads.
This is related to the method and device for arbitrarily adjusting the height, etc. When threading the decorative thread looper at the end of sewing on this type of sewing machine, there is a tension between the hook part and the 9th part at the end of the decorative thread sewing. The triangular shape formed by the decorative threads at the end of the stitching changes depending on the number of needles, the needle d], the movement trajectory of the looper depending on the type of machine, etc. When inserting the decorative thread into the triangular shape, the decorative thread can be easily caught and pulled with one thread, and the decorative thread can be cut well between the lower knife and the lower knife. It's difficult,
The purpose is to adjust the upper knife to suit the conditions so that it can make good cuts.
