Embodiment Construction

[0068] figure 1 A highly simplified diagram of the Axminster loom. This loom is used for the processing of pile fabrics. It comprises several warp beams (not shown) feeding several warp threads 2,3,4. The shed is formed with warp threads 2, 3, 4, whereby one or mostly two weft threads 5 are loaded into said shed, as figure 2 shown. The sheds are formed with the use of heald frames 6, 7, 8 which guide the warp threads 2, 3, 4 through the healds.

[0069] A gripper device 10 comprising several grippers 11 is used to introduce pre-cut pile yarns 9 into the fabric. The gripper device 10 comprising the gripper 11 is movable between its first position A, in which it introduces the pile yarn 9 into the fabric, and its second position B, in which it withdraws the pile yarn from the thread guide 12 . The yarn guide 12 is able to hold several yarns 13, 14 of different colors at the ready and can be controlled in such a way as to retrieve the desired yarn respectively, for example...

Abstract

The gripper has two clamping jaws (19,21) with the gripping surface for clamping a pile yarn (9). A hinge (32) connects both the clamping jaws with one another in a rotatable manner and determines a rotation axis (33). One clamping jaw has an axial bearing surface (36) for forming the hinge, where a spacer has an attachment surface (39). A holding element (46) rests on the attachment surface and comprises a plate-shaped or disk-shaped head (48). An axial bearing surface (49) is held by the spacer at a distance from the axial bearing surface of the clamping jaw.

Description

technical field [0001] The invention relates to a yarn gripper for an Axminster loom. Background technique [0002] Axminster looms are known for making carpets and other pile fabrics. The main functions of this loom are known from the reference "Carpet Manufacture" (Geoffrey H. Crawshaw, WRONZ Developments, Private Bag 4749, Christchurch, New Zealand). The loom operates with three sets of warp threads associated with the corresponding heald frames. Grippers located on the rods are used to deliver pre-cut pile yarns between the warp threads, where they are anchored by means of weft threads. [0003] Axminster weaving machines achieve high precision requirements by operating the grippers. The simultaneously working grippers on the rod must be able to grip the yarns in a precise manner and transfer them between the warps. Thus, the gripper must be relatively narrow to fit between the warp threads. As such, grippers usually consist of two extremely narrow jaws held togethe...
