Patent number: 7806146Abstract: In order to solve the problem of not having enough space available for a large number of components and keeping the deflection of the electric motor small in a device for controlling the transverse movement of the warp threads of a textile weaving machine, particularly a textile weaving machine with single strand movements, the invention proposes to operatively connect the strands via power transmission elements having different lengths in a staggered or register-like way to an electric motor and to provide the electric motors with a ratio in relation to the strands such that the movement of the electric motors brings about a greater movement of the strands.Type: GrantFiled: November 12, 2007Date of Patent: October 5, 2010Assignee: Textilma AGInventor: Silvan Borer

Patent number: 7610939Abstract: The invention relates to a Jacquard machine, comprising 2 sets of knifes moving up and down in opposition, which each, at each of their extremities, are taken up in separate knife grids (4a, 4b) being driven by a cinematic drive chain (30), and each, at one of their extremities (20a, 20b), being guided into a straight motion by means of a “Watt's linkage” rod system, the height of lift of each of these extremities (20a, 20b) of the knife grids (4a, 4b) being adjustable, and the knife grids (4a, 4b) each at their first extremities (20a, 20b) being linked with at least one first driving lever (2, 2a, 2b, 10) by means of a first linking rod (3a, 3b), and at their second extremities (21a, 21b) being linked with at least a second driving lever (2, 10) by means of a second linking rod (14a, 14b), wherein per knife grid (4a, 4b) one or several elements (1, 101, 1a, 1b, 3a, 3b) of the Watt's linkage rod system are part of the cinematic drive chain (30), and the amplitude of the motion of the said extremity (20a, 20b)Type: GrantFiled: April 10, 2006Date of Patent: November 3, 2009Assignee: N.V.

Patent number: 7117898Abstract: A guide rod assembly for a Jacquard loom is described which is narrower (10 mm or less), instead of 13 mm of conventional guide rods. This reduction in width is attained reducing the overall height of the magnet system integrated in the guide rod. The magnet system has a support member in the form of an iron core with an elongated or oval cross-section, with an excitation coil wound around the iron core. Pole strips are in contact with both front faces of the iron core. The respective top surfaces of the pole strips are spaced apart by less than 13 mm.Type: GrantFiled: December 3, 1999Date of Patent: October 10, 2006Assignee: Michel Van de Wiele NV Carpet and Velvet MachineryInventors: Norbert Irmer, Peter Wahl

Patent number: 7000647Abstract: The invention on the one hand relates to a device for attaching and guiding of at least one tackle cord (2) in a Jacquard machine, the device (1) being designed for being attached to a part (20) of the Jacquard machine and being designed for being connected to at least one tackle cord (2), the device (1) being provided with a springy element (15) exercising a pushing force on the device (1) in a direction which is opposite to the tractive force exercised on the device (1) by the tackle cord (2). The invention further relates to a Jacquard machine, which is provided with a fixed, adjustable or movable grid and a number of retaining plates, which are attached to the grid and which are provided for attaching a number of devices according to anyone of the above-mentioned claims.Type: GrantFiled: May 6, 2003Date of Patent: February 21, 2006Assignee: N.V.

Patent number: 6880582Abstract: A first (1) and a second connecting means (2) which may be connected in a detachable manner in order to connect a first and a second cord, more particularly a lifting cord and a harness cord of a Jacquard machine, the first connecting means (1) comprising an elastically deformable coupling element (3) which may be received in a receiving part (4) of the second connecting means and may be retained in axial direction, the second connecting means (2) comprising a passage (5) through which the coupling element (3), compressed in the radial direction, may be moved to the receiving part (4) and the coupling element (3) in the receiving part (4) having the possibility of adopting a larger radial dimension than is necessary to be moved through the passage (5), so that the coupling element (3) snap-fits in the receiving part (4). In the receiving part (4), the coupling element (3), by rotation around the longitudinal axis (A), may be brought into a disengaging position in which it is not retained.Type: GrantFiled: May 6, 2003Date of Patent: April 19, 2005Assignee: N.V.
