摘要：
A method for cutting the lower and at least one upper thread for lead-in embroidering or lead-in sewing is performed with a device including thread catchers (19a-19c) connected with each other in a fixed manner and layered over top of each other, formed of sheet metal, as well as spring and thread tightening plates (31 and 41) arranged above and below the thread catchers, which move back and forth against a blade (29), and a thread wiper unit. The device is exclusively operated by a drive moving back and forth and driving the thread cutting and lead-in stitching unit (5).
