Abstract

A compressed-air thread splicing device for producing a knotless thread connection by splicing, the device having a splicing channel for receiving therein threads to be spliced to one another, the splicing channel being formed with at least one compressed-air injection opening and affording at least one of a plurality of operations to be performed on the fibers of the threads consisting of tangling, hooking, whirling and entwining the thread fibers mutually includes a first device for forming a thread guide contour edge at one end of the splicing channel, and a second device for forming a thread guide contour edge at the other end of the splicing channel, the thread guide contour edges partly covering a respective outlet and inlet of the splicing channel, and a controllable device for holding at least end fibers of ends of the threads in friction contact with at least one of the thread guiding contour edges during the splicing operation.
