Abstract
Method of tying an upper thread to a lower thread by means of a device having a splicing chamber formed with an elongated slot for laying-in and tying the threads, including mutually tying the threads by splicing with compressed air acting thereon from a side, moving a thread regulator from a thread take-up location to a thread delivery location for laying-in the threads into the elongated slot of the splicing chamber, automatically severing the ends of the upper and the lower threads, blowing compressed air into the splicing chamber, and sucking in and firmly holding each newly formed shorter thread end by means of an air current, which comprises producing the air current for sucking-in and firmly holding the thread ends as a suction air current by means of an injector to which compressed air is admitted, and guiding the suction air current simultaneously in an approximately helical path, and a device for carrying out the method.
