Publication number: 20240026577Abstract: A spinning element of an air-jet spinning nozzle for an air-jet spinning machine for producing a yarn from a sliver using an airflow. The spinning element of the air-jet spinning nozzle for the air-jet spinning machine and a corresponding air-jet spinning nozzle allows a particularly inexpensive, low-maintenance, and simple operation of an air-jet spinning machine without compromising the quality and strength of the air-jet spun yarn and without requiring frequent cleaning. This is achieved in that the spinning element has at least one fibre- and/or thread-guiding surface, an anti-adhesive coating being located on at least some sections of the fibre- and/or thread-guiding surface.Type: ApplicationFiled: November 24, 2021Publication date: January 25, 2024Inventors: Jochen DRESSEN, Karoline GÜNTHER, Chandrassekaran SESHAYER, Ralf SIEWERT, Thomas WEIDE

Patent number: 6955037Abstract: An open-end spinning device comprises a spinning rotor (21) rotating in a rotor housing with a spinning insert (24) supported rotatably with respect to the spinning rotor (21) coaxially to the rotor axis (33). The spinning insert (24) can be caused to rotate as a function of the rotary motion of the spinning rotor (21) via a contactless entrainment of the spinning insert (24) by means of permanent magnets (32) attached to the spinning insert (24). In this manner a simple and reliable entrainment and an automatic adjusting of the rotational speed of the spinning insert (24) in the spinning rotor (21) are achieved.Type: GrantFiled: November 21, 2003Date of Patent: October 18, 2005Assignee: Saurer GmbH & Co.

Patent number: 6920746Abstract: An open-end spinning device has a spinning rotor (2) with a rotor groove (25) at its greatest inside diameter in which fibers are collected. A yarn shank (27) extending from a yarn withdrawal nozzle to the rotor groove (25) is curved in the vicinity of the rotor groove (25) counter to the direction of rotor rotation during the spinning process forming a lagging tie-up zone whereat yarn formation takes place. A rotor insert (18) is rotatably supported within the spinning rotor coaxially to the rotor axis. The rotor insert (18) can be caused to rotate in a contactless manner by the rotation of the spinning rotor. The rotor insert (18) comprises a yarn guide conduit (20) that receives the yarn shank (27) to effect a retardation of the rotor insert (18) during normal spinning operation, which significantly improves the stability of the spinning process over known open-end spinning devices.Type: GrantFiled: November 21, 2003Date of Patent: July 26, 2005Assignee: Saurer GmbH & Co.
