Patent number: 9109307Abstract: A yarn treatment chamber for thermal treatment of a running yarn, with a center zone, in which a pressurized hot, gaseous or vaporous medium acts on the yarn, and end zones on both sides of the center zone, in which a cooling, gaseous medium is active. The end zones have a yarn inlet or outlet openings with a yarn sluice, which seals the associated end zone and the yarn treatment chamber. The yarn inlet and outlet openings (2, 3) are arranged such that the yarn (14) must change direction, and the yarn treatment chamber (21 has yarn deflection means (12) to guide the yarn (14) between the yarn inlet and outlet openings (2, 3). Both the yarn sluice (23A) and the yarn sluice (23B) are accessible without problems to operating staff at an ergonomically favorable height below the yarn deflection means (12) of the yarn treatment chamber (21).Type: GrantFiled: July 20, 2012Date of Patent: August 18, 2015Assignee: Saurer Germany GmbH & Co.

Publication number: 20050082404Abstract: A creel is provided with two insert pegs that are mounted on a retainer secured to a machine frame that is pivotable between a lower loading station and an upper loading position. The creel also includes a yarn guide element with a longitudinal opening whose length substantially corresponds to the vertical spacing between the axes of the insert pegs such that the ends of the longitudinal opening can be brought into a position lying substantially on the extension of the insert peg axes. Two elongate guide organs are mounted on the side of the yarn guide element and each has a yarn eye opening. The creel further includes a yarn retaining organ located between the insert pegs at a lateral spacing from the plane defined by the insert peg axes and whose retaining force lies under the withdrawal force by which the yarn is drawn off a feed package.Type: ApplicationFiled: October 15, 2004Publication date: April 21, 2005Applicant: Saurer GmbH & Co.
