Abstract: A nozzle system for a textile machine comprising at least one nozzle element and a connecting element for connecting the nozzle element to a textile machine. The connecting element comprises at least one quick fastening system. The quick fastening system comprises a first and a second position. In the first position the quick fastening system is connected to the connecting element so that the nozzle element can be fastened to the quick fastening system in such a way that the nozzle element can be removed without auxiliary devices. The quick fastening system is designed in such a way that in the second position the nozzle element is immovably fastened to the connecting element.

Abstract: A suction device (100) for a textile machine comprising a mouthpiece (2) for introducing at least one yarn, a suction pipe (3) for guiding the yarn and a suction element (5) for generating a suction pressure. The suction element (5) comprises at least two cyclone elements (1a, 1b) for generating a vortex flow of compressed air. The cyclone elements (1a, 1b) are arranged one behind the other in the suction direction (A), so that a yarn can be passed first through a first cyclone element (1a) and then through a second cyclone element (1b). Each cyclone element (1a, 1b) comprises a cyclone axis, the cyclone axes being aligned in particular coaxially. Each cyclone element (1a, 1b) comprises at least one opening (31a, 31b) at the periphery, which is connected to a preferably common air delivery system (12), in particular in such a way that vortexes in both cyclone elements (1a, 1b) have the same direction of rotation. The suction device (100) comprises in particular a Laval nozzle (13).

Abstract: A splicing head (100) for a splicing device comprising a splicing chamber and a clamping device (8) for clamping yarns. The clamping device (8) is disposed between two sections (4) of the splicing chamber. The clamping device (8) is arranged independently operable on the splicing head (100), so that the clamping device (8) is operable before and/or after closing the splicing chamber. The splicing head (100) comprises at least one drawing-in element for ensuring that the yarn ends are included in the splicing process, in particular for drawing the yarn ends into the splicing chamber.

Abstract: The invention focuses on a molded part (12) for a nozzle core (60) for stuffer-box crimping of threads. The molded part includes a ceramic body (121) with a planar surface (122). Receiving contours (124) for receiving fastening means (50) are arranged in the planar surface (122). The receiving contours (124) are open in the lateral direction.
