Patent number: 8043193Abstract: A gear mechanism for the drive assembly of a heald shaft (1), wherein the gear mechanism (6, 6a, 6b, 6c) comprises an input shaft (7, 7b, 7c) and an output shaft (5, 5b, 5c). The gear mechanism (6, 6a, 6b, 6c) generates a differential angle of rotation between the input shaft (7, 7b, 7c) and the output shaft (5, 5b, 5c) that is superimposed on the angle of rotation and, in dependence on the angle of rotation, is subjected to an oscillating change. This oscillating change can differ from a harmonic oscillation as a result of the non-circular design of the planet gears (11a, 12a, 13a) of the gear mechanism (6, 6b, 6c), thereby making it possible to realize almost any optional movements for the heald shaft (1), with low strain on the gears and the bearings. A simple production method and a compact design are disclosed.Type: GrantFiled: November 26, 2007Date of Patent: October 25, 2011Assignee: Groz-Beckert KGInventor: Gerhard Pohl

Patent number: 7281548Abstract: An improved heddle (2), on its end eyelet (7), has a spring means (14) which braces the end eyelet (7) resiliently in at least one direction on a heddle support rail 3. The spring means (14) serves to avoid play between the heddle (2) and the heddle shaft (1). This provision makes it possible to increase the operating speed of power looms.Type: GrantFiled: December 2, 2003Date of Patent: October 16, 2007Assignee: Groz-Beckert KGInventors: Thomas Schmid, Gerhard Pohl, Johannes Bruske

Publication number: 20070137719Abstract: The heddle shaft (1) according to the invention combines a traditional heddle machine (2) with an eccentric toothed gearing to purposely allow the heddle shaft (1) to dwell for longer periods of time in the upper and lower reversing region and to reduce any accelerations that occur. This permits an increase in the weaving speed and/or the weaving widths. For a particularly advantageous embodiment, a coupling device is additionally provided, which gives the heddle shaft (1) a pendulum movement with a stroke ranging from a few millimeters to centimeters during the idle phases, meaning when no sheds are formed. As a result of the pendulum movement of the heddle shaft (1) in the upper or lower reversing region, the acceleration loads on the heddle shaft (1) can be further reduced.Type: ApplicationFiled: December 15, 2006Publication date: June 21, 2007Applicant: Groz-Beckert KGInventor: Gerhard Pohl
