Abstract: The invention relates to an interlacing nozzle (100) for the production of knotted yarns, interlaced yarn, of DTY or plain yarns with knots. The interlacing nozzle (100) comprises a yarn channel (1) with an air twist chamber (2). The air twist chamber (2) includes an injection port (4) for introducing air into the air twist chamber (2). A channel axis (M) extends in a yarn guiding direction (F). The yarn channel (1) comprises a channel width (21) transverse to the channel axis (M). The air twist chamber (2) comprises a chamber length (29) in the yarn guiding direction (F) and a chamber extension (28) transverse to this length. The chamber length (29) is at least 180% of the chamber extension (28), preferably at least 200% of the chamber extension (28), and preferably the chamber length (29) is at least 1.5 mm longer than the chamber extension (28).

Abstract: Nozzle (1) for manufacturing knotted yarn (11), having a yarn duct (2) in which knots are producible with the aid of air entanglement. The nozzle includes at least one air bore (3) having a longitudinal axis (A), which merges with the yarn duct (2) in a merging opening (4). Air is introducible into the yarn duct (2) through the air bore. The longitudinal axis (A) of the air bore (3) is disposed at an angle of less than 90°, preferably 65-85°, particularly preferably 78° in relation to a conveying direction (B) of the knotted yarn (11). A baffle face (5) is configured on the opposite side of the merging opening (4) of the air bore (3) in the yarn duct (2), so as to be substantially perpendicular in relation to the longitudinal axis (A) of the air bore (3).

Abstract: The invention relates to a nozzle system (100) for a textile machine. The nozzle system (100) comprises at least one nozzle element (1) and a connecting element (2) for connecting the nozzle element (1) to a textile machine. The connecting element (2) comprises at least one quick fastening system (3). The quick fastening system (3) comprises a first and a second position. In the first position, the quick fastening system (3) is connected to the connecting element (2) so that the nozzle element (1) can be fastened to the quick fastening system (3) in such a way that the nozzle element (1) can be removed without auxiliary means. The quick fastening system (3) is designed in such a way that in the second position the nozzle element (1) is immovably fastened to the connecting element (2).

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: A thread guiding device (100) for guiding threads. The thread guiding device (100) comprises a main element (1), at least one cover element (2) and at least one thread guide (3). The at least one thread guide (3) is, or can be, arranged in a recess (11) of the main element (1). The thread guide (3) is, or can be, removably secured to the main element (3) by the cover element (2).

Abstract: A molded part (12) for a nozzle core (60) for crimping threads. The molded part comprises a ceramic body (121) having a planar surface (122). Receiving contours (124), for receiving a fastening mechanism (50), are arranged in the planar surface (122). The receiving contours (124) are open in the lateral direction.
