Patent number: 11613829Abstract: Bearing for a shed-forming machine or a system for transmitting movement to the frames of a loom, which has an inner ring, an outer ring and rolling elements. The inner ring is centered on a major axis, has two lateral surfaces normal to the major axis, and defines a circular peripheral path centered on the major axis. The outer ring defines an inner path, which is circular and centered on the main axis. The rolling elements are interposed, radially with respect to the main axis, between the peripheral ring and the inner ring, to guide the outer ring in rotation relative to the inner ring around the main axis. The inner ring has at least one slot, opening onto the two lateral surfaces, extending opposite a portion of the peripheral path, and forms a bridge of material between the slot and the peripheral path.Type: GrantFiled: November 13, 2020Date of Patent: March 28, 2023Assignee: STAUBLI FAVERGESInventors: Francois Pollet, Sebastien Marion

Patent number: 8251102Abstract: A heddle frame (1) is driven via drive rods (15), which pass through its lateral sampsons (13). To that end, the lateral sampsons (13) each have a corresponding channel (19). The play between the circumferential face (22) of the drive rods (15) and the channel wall face (21) of the respective channel (19) has an intermediate layer (24), which extends over the full length, or portions, of the drive rod (15). The intermediate layer (24) preferably comprises an impact-proof, permanent-elastic, damping material. A slight residual play allows the introduction of the drive rods (15) and the intermediate layer (24) into the channel (19) without force.Type: GrantFiled: October 3, 2005Date of Patent: August 28, 2012Assignee: Groz-Beckert KGInventor: Franz Mettler

Patent number: 7617845Abstract: A heald shaft (1) for coupling the shaft rods (2) with the end binders (5), having connecting joints or hinges (10) whose pivot axes (14) lie externally of the shaft rods (2) and preferably inside the end binders (5). Due to the connecting joints (10), a moment-free coupling between the shaft rods (2) and the end binders (5) is ensured. The relative pivotal motions between the shaft rods (2) and the end binders (5) appearing during operation do not generate any moment transmissions between the shaft rods (2) and the end binders (5). Preferably, the driving couplers (7) are arranged above the end binders (5) in a direct extension thereof.Type: GrantFiled: June 26, 2006Date of Patent: November 17, 2009Assignee: Groz-Beckert KGInventors: Stefan Drope, Johannes Bruske, Karl-Heinz Gesing

Patent number: 7500495Abstract: An end binder (5) for a heald shaft (1) is formed by a bent sheet metal member (9) which preferably has a U-shaped cross section and which, according to the preferred embodiment, is of high-grade steel. The open side of the U-section faces the shaft rods (2,3). In the hollow space enclosed by the bent sheet metal member (9) shaft rod couplers (28) are secured which are preferably pivotally held. The upper or lower end of the bent sheet metal member forms part of a driving coupler (25) which is situated preferably in a linear continuation of the bent sheet metal member (9) and is a one-piece component with the end binder (5). Such a structure may be manufactured in a simple manner with very small tolerances, and it has a low weight, a substantial stiffness and highly satisfactory bearing properties for being supported in plastic guides.Type: GrantFiled: June 26, 2006Date of Patent: March 10, 2009Assignee: Groz-Backert KGInventors: Johannes Bruske, Stefan Drope, Karl-Heinz Gesing, Stefan Danner

Patent number: 7481249Abstract: A reed drive of a loom includes a reed shaft connected to a reed. A conversion gearing having an input element and an output element is provided at each end of the reed shaft. The input elements are coupled to driven shafts of electromotive rotary drives to produce a common rotational motion with the same rotational speed as the driven shafts. The conversion gearings convert the rotating motion of their input elements into a reversible rotation of the output elements, and the output elements are coupled to the reed shaft in a rotationally fixed manner. Thus, the number of complete rotations of an input element is equal to the number of complete motion cycles of the reed shaft per unit of time.Type: GrantFiled: August 26, 2005Date of Patent: January 27, 2009Assignee: Lindauer DORNIER Gesellschaft mbHInventors: Valentin Krumm, Dietmar Von Zwehl, Michael Lehmann, Thomas Laukamp

Publication number: 20090000687Abstract: A shaft connecting device (18) that comprises a thrust rod (8) and a lateral support (4) that fit into each other with minimal transverse play. In addition, the shaft connecting device (18) comprises a clamping device (16) with a stop means (60, 60?, 66) and a fixation means (30, 30?), the latter connecting the lateral support (4) and the thrust rod (8) exclusively on their respective upper ends to each other. Any opening, closing and adjusting of the connections between the thrust rod (8) and the lateral support (4) is possible in a particularly simple and convenient manner. The lateral support (4) and the thrust rod (8) support each other, thus resulting in a high dynamic load-bearing capacity. The overall design is simple, clear and cost-effective.Type: ApplicationFiled: June 26, 2008Publication date: January 1, 2009Applicant: Groz-Beckert KGInventors: Karl-Heinz GESING, Johannes Bruske

Patent number: 5435352Abstract: A method of manufacturing multiaxial thick woven fabrics (8) using healds (3) through which warps are passed, a shuttle (5) reciprocating so as to insert wefts (6) in a warp shedding portion (19) formed by the healds, a reed (9), and a woven fabric removing device (10). A large number of healds are provided in parallel in the direction of woven fabric removal. The shedding portion is formed by passing a plurality of warps so that predetermined thickness and width of the woven fabric are produced through the healds and by widely reciprocating the healds in the width direction, moving the shedding position sequentially from one side to the other side, inserting a weft sequentially in the shedding portion and arranging it by shifting the weft position in the width direction. A texture of the first row of predetermined width and thickness is formed by fixing warps.Type: GrantFiled: June 4, 1993Date of Patent: July 25, 1995Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Tetsuya Yamamoto, Shigeru Nishiyama
