Locked Open Shed Patents (Class 139/63)
  • Patent number: 7610939
    Abstract: 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)

  • Patent number: 7398799
    Abstract: A device for hooking a heddle of a weaving loom of the Jacquard type to a harness cord of the loom that includes an endpiece molded on an upper end of the heddle. The endpiece including an aperture for the passage and wedging of the cord and a housing for receiving two strands of the cord. The device also includes a rigid sleeve reciprocally slidably mounted on the endpiece between a first position, in which it allows access to the aperture, and a second position, in which it covers the aperture and exerts a compressive force for constricting the aperture and blocking access to the lower end of the cord. The device may also be used for hooking one or more cords on a string.

  • Patent number: 7117898
    Abstract: 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.

  • Patent number: 7025094
    Abstract: On the one hand, the invention relates to a device for exerting a return force on at least one harness element of the harness of a Jacquard weaving machine, comprising at least one return spring (2) provided with means of attachment (1) for attaching the return spring (2) to retaining means (4) being immovably provided, said means of attachment (1) being provided with a positioning opening (6) for positioning the means of attachment (1) with respect to the retaining means (4), and a fixing opening (7) for fixing the means of attachment (1) to the retaining means (4), a spring connection (8) being provided between the positioning opening (6) and the fixing opening (7), in such a manner that the means of attachment (1) are able to move from positioning opening (6) to the fixing opening (7) with respect to the retaining means (4), but after having been fixed will be unable to move back from the fixing opening (7) to the positioning opening (6) with respect to the retaining means during operation or transport of

  • Patent number: 4858654
    Abstract: A pulley-block drive of an open shed Jacquard mechanism is sectionally controlled by a movable suspension apparatus. Pulley bands or harness cords are attached to one of the ends of the movable suspension apparatus. The movable suspension apparatus is suspended from hooks which can engage with the knives of the jacquard machine so that the movable suspension apparatus is driven by the knife grid of the jacquard mechanism.
