Patent number: 11629442Abstract: A device for fastening a gripper on a gripper shaft of a textile machine, in particular a sewing machine, preferably a multi-needle sewing machine, with a support element for the gripper is described. The support element for the gripper is connected to a holder or the gripper shaft via a connecting element in such a way that the support element for the gripper is detachable from the holder or the gripper shaft. The connecting element is designed as a toggle screw or locking mechanism such that the toggle screw rotatably engages through a bore in the support element into a corresponding opening in the holder or the gripper shaft, engaging behind an abutment, or the locking mechanism is designed as a positive connection between the support element and the holder.Type: GrantFiled: May 5, 2020Date of Patent: April 18, 2023Assignee: Nähmaschinenfabrik Emil Stutznäcker GmbH & Co. KGInventors: Hartmut Klapp, Hans-Rochus Groß

Publication number: 20090148284Abstract: A vacuum pump for producing a vacuum in a space which is to be evacuated comprises a housing (10) having a cylindrical inner space (22). An expeller (26) is arranged eccentrically in the inner space (22). A helical sealing element (34) is provided between the expeller (26) and an inner wall (38) of the housing (10) for forming at least one crescent-shaped conveying space. The housing (10) or the expeller (26) are connected to a drive device (44) for producing a relative rotary movement between the housing (10) and the expeller (26). The vacuum pump is configured as a dry-running vacuum pump.Type: ApplicationFiled: January 11, 2007Publication date: June 11, 2009Inventors: Thomas Dreifert, Hans-Rochus Gross

Patent number: 7153093Abstract: A vacuum pump (10) comprises at least one rotor shaft (12) having a rotor section (14) with a rotor (16), a bearing section (18) with a bearing (20), and a shaft sealing system (22) that is axially situated between the rotor section (14) and the bearing section (18). The shaft sealing system (22) axially comprises, on the side of the rotor, a gas seal (32) and, on the side of the bearing, an oil seal (34). The shaft sealing system (22) additionally comprises, between the gas seal (32) and the oil seal (34), a separating chamber, which surrounds the rotor shaft (12) and is ventilated by at least one separating chamber ventilation duct (60, 62). This enables the pressure difference that decreases via the gas seal and the pressure difference that decreases via the oil seal to be adjusted. An appropriate adjustment can prevent oil on the bearing side from passing through the oil seal toward the separating chamber.Type: GrantFiled: February 18, 2003Date of Patent: December 26, 2006Assignee: Leybold Vacuum GmbHInventors: Thomas Dreifert, Wolfgang Giebmanns, Hans-Rochus Gross, Hartmut Kriehn

Patent number: 6406650Abstract: A spinning apparatus for producing a plurality of yarns, wherein the yarns are produced by combining a plurality of filament bundles. To this end, the spinning apparatus includes a plurality of extruders for producing a plurality of melt flows, which are distributed by a plurality of distributor pumps to at least two spinning positions that are arranged side by side. Each of the spinning positions includes a plurality of spinnerets, which extrude a partial flow from a distributor pump to a filament bundle. Also, the spinning positions are arranged so that at least one filament bundle of one spinning position can be combined to a yarn with at least one filament bundle of an adjacent spinning position.Type: GrantFiled: March 10, 2000Date of Patent: June 18, 2002Assignee: Barmag AGInventors: Hans-Rochus Gross, Jorg Hegenbarth, Frank Bäcker

Patent number: 6378180Abstract: The invention relates to a method and an apparatus for spinning and crimping a multifilament yarn, and wherein a thermoplastic melt is extruded through a spinneret to form a filament bundle. The filament bundle is divided into a plurality of bundle components before being crimped. Each bundle component is separately crimped and combined to a multifilament yarn after being crimped. The yarn is subsequently wound to a package.Type: GrantFiled: April 11, 2001Date of Patent: April 30, 2002Assignee: Barmag AGInventors: Mario Maranca, Frank Bäcker, Hans-Rochus Gross
