  • Patent number: 7971544
    Abstract: A quick-release clamping holder for a sewing needle, embroidery needle or the like has a needle receptacle (2) on which a needle clamping part (8) is preferably pivotally supported. A fixing element (14) is provided in order to clamp and fix the needle clamping part (8) in place, whereby said fixing element is pivotally or rotatably supported relative to a longitudinal central axis (13) of the needle and thus can be slid onto and off the needle clamping part (8). Actuation is simple and safe.
    Type: Grant

  • Patent number: 7707953
    Abstract: The inventive gripper device for a tufting machine comprises a gripper device (10). The gripper device contains a gripper (11) and a guide member (12) that has a cutting edge. The gripper (11) has two gripper sections that are at a distance from each other in the direction of movement and are preferably separated from each other by a step (33) and/or by an extension (34), said gripper sections being configured as gripper edges that are parallel to each other, but spaced apart and offset with respect to each other in view of the pile height direction. The reversal between cut pile operating mode and looped pile operating mode takes place by means of the longitudinal adjustment of the gripper (11).

  • Patent number: 7520229
    Abstract: A gripper device in accordance with the invention comprises a gripper (3) and a counter knife element (4) that are fabricated separately and joined. As a result of this, optimal material combinations are possible, which will deal with both types of wear, namely between the gripper (3) and the tufting needle (5), on the one hand, and between the knife (6) and the counter knife element (4), on the other hand. The gripper module (1) accommodates the counter knife element (4), which, in turn, supports the gripper (3). The two parts may be joined by caulking, cementing, riveting, screwing or similar measures, or they may be cast together in the gripper module (1). The cutting of the loop is done exclusively between the counter knife element (4) and the knife (6).
