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.

Device for performing a knot-free connection of the ends of two threads formed of textile fibers of limited length having at least one twisted fiber strand, comprising a splicing device for receiving the two threads coming from opposite sides into said splicing device and for mutually tangling, intermixing and intertwining individual fibers of the two threads, means for trimming the end of each thread to a predetermined distance from said splicing device, two thread end preparation units each being disposed in vicinity of said splicing device for vibrating, loosening, combing and separating each respective thread end into individual fibers, each of said thread end preparation units including a mostly pneumatically acting part and a mostly mechanically acting part, each of said mostly pneumatically acting parts having a longitudinal slot formed therein for holding and guiding a thread, at least one compressed gas supply channel terminating in each respective slot across the thread end, and each of said mostly mechanically acting parts having at least one contact surface being movable in direction toward the thread and contacting the fibers, means for directing at least part of the compressed gas from said respective mostly pneumatically acting part over said contact surfaces for beating, pulling and tearing with mechanical and pneumatic stresses in direction toward the thread ends, means for withdrawing the prepared thread ends from opposite sides up to said splicing device, a compressed gas line blowing compressed gas into said splicing device obliquely to the longitudinal direction of the individual fibers for cleaning and spreading apart each thread end and for tangling, mixing and hooking the individual fibers of the two threads to each other to form a splice connecting the threads after setting said splicing device in operation, means for introducing a thread twist into the splice, and means for releasing the connected threads from said splicing device.
