Abstract

Method for the knot-free connection of two threads formed of textile fibers of limited length having at least one twisted fiber strand, including a splicing device for mutually tangling, intermixing and intertwining individual fibers of the two threads, which includes inserting the two threads coming from opposite sides into the splicing device, trimming the end of each thread to a predetermined distance from the splicing device, vibrating, loosening, combing and separating the thread ends into individual fibers, cleaning and spreading apart each thread end by blowing compressed air into the splicing device obliquely to the longitudinal direction of the individual fibers and by beating, pulling and tearing with mechanical and pneumatic stresses in direction toward the thread ends, withdrawing the prepared thread ends from opposite sides up to the splicing device, tangling, mixing and hooking the individual fibers of the two thread ends to each other to form a splice connecting the threads after setting the splicing device in operation, introducing a thread twist into the splice, and removing the connected threads from the splicing device, and a device for carrying out the method.
