Abstract: A loop gripper (10) for a tufting machine has a gripper body (11) with a gripper finger (12) extending in an extension direction E from a retained end (13) to a free end (14). On the gripper finger (12) underside (16), a cutting region (20) transitions into a sliding surface (19) at a transition point (21). A retaining element (35) near the transition point (21) is mounted to be pivotable about a pivot axis S relative to the gripper finger (12). The pivot axis S extends in a transverse direction Q at right angles to the extension direction E. The retaining element (35) is urged into a starting position A by a force, for example a spring force and/or a weight force. In the starting position A, a retaining surface (37) of the retaining element (35) extends obliquely or at right angles away from the sliding surface (19).

Abstract: An improved tufting knife (20) has, at a distance from its cutting edge (36), a bending joint (27) from which extends one leg (26) to the cutting edge (36) and another leg (25) to a knife bar (21). The bending joint (27) ensures that the tufting knife (20) is highly flexible and that a desired contact pressure between the tufting knife (20) and the gripper (18) is maintained largely independently of the degree of lateral flexion and/or bending of the tufting knife (20). This has a strongly wear-reducing effect.

Abstract: A gripper (3) for a tufting machine comprises a gripper body (9) having a cutout (22) for a cutting insert (10), said cutting insert preferably consisting of a hard metal. Connecting means acting in a form-closed manner are provided for the connection of the cutting insert (10) with the gripper body (9). In their simplest embodiment, said connecting means are formed by the deformation regions (37, 38) that are provided on the gripper body (9) and that reach around matching cutouts (33, 34) of the cutting insert (10).

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.

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).

Abstract: A tool 1 for a textile machine with the tool having a wear-minimizing coating on its basic tool body 2, which wear-minimizing coating acts as an anti-wear element 15. In order to accommodate this coating, the basic tool body 2 is provided with a recess at a suitable location, and the coating is built up on the bottom of the recess, for example, by plasma-spraying. Preferably, an oxide-ceramic material is used for the coating.

Abstract: A gripper (3) for tufting machines comprising a slider (18) that is supported in a gripper body to be movable in longitudinal direction and that is arranged in a slider receiving space (17) which, preferably, is configured as a slit. The slit extends from the lower narrow side (12) of the gripper body (4) into the gripper body. The slit is limited by two thin walls (19, 20) or, alternatively, by only one thin wall (20). A cutting edge insert receiving space 39 is provided above the slider receiving space (17), with the receiving space (39) extending from the flat side (9) end being recessed in the gripper body (4). Between the cutting edge insert receiving space (39) and the slider receiving space (17), a strip (40) is provided that preferably extends in longitudinal direction of the gripper body (4) and separates the receiving spaces (39, 17) from each other.

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).

Abstract: A needle holder (7) is provided, in particular, for industrial sewing machines, in which sewing machine needles having different needle gauges and preferably different cylindrical shanks or shafts are supported or held in such a manner that they can be adjusted in a transverse direction. This permits an adjustment of the relative position between the sewing needle (4) and the gripper (6), without requiring an adjustment of the gripper position and/or the needle guard position.

Abstract: The new gripper design provides a gripper (3) for tufting machines, said gripper comprising a slider (18) that is supported so as to be movable in longitudinal direction. This slider is arranged in a slider receiving space (17) which, preferably, is configured as a slit. The slit extends from the lower narrow side (12) of the gripper body (4) into said gripper body. Said slit is limited by two thin walls (19, 20) or, alternatively, by only one thin wall (20). A cutting edge insert receiving space 39 is provided above the slider receiving space (17), said receiving space (39) extending from the flat side (9) and being recessed in the gripper body (4). Between the cutting edge insert receiving space (39) and the slider receiving space (17), a strip (40) is provided that preferably extends in longitudinal direction of the gripper body (4) and separates the receiving spaces (39, 17) from each other. This design is suitable for the creation of very narrow grippers (3) that permit a division of less than 1/10 Inch.

Abstract: A novel tufting needle (4) is distinguished by a hollow flute (15) which is preferably symmetrical to a central plane (29) and which is bilaterally provided with chamfers (33, 34). The chamfers (33, 34) are, in an inward-located, that is, in a region lying close to the central plane (29), inclined at a small acute angle (?) to a reference plane (28), while in a region bordering an externally located rim (edges (46, 47)), the chamfers (33, 34) are inclined at a larger acute angle (?) to the reference plane (28). This feature improves the rigidity, the tufting properties and the mechanical strength, as well as the wear resistance of the novel tufting needle (4).
