Rapier and gripper weaving machine

Abstract

Rapier for a gripper weaving machine and gripper weaving machine, wherein the rapier (1) comprises a gripper band (2) and a wear-resistant element (20) which is added to the gripper band (2), the gripper band (2) comprises a stiff top (10) to which the wear-resistant element (20) can be connected, the stiff top (10) and the wear-resistant element (20) comprise complementary connecting parts (6, 7) which comprise a tongue (11) and a recess (21), the tongue (11) can be introduced by sliding it into the recess (21) in an introduction direction (I) and the tongue (11) is held in the recess (21) in a form-fitted manner in the directions other than the introduction direction (I), wherein a gripper (3) can be attached to the stiff top (10) and to the wear-resistant element (20) by fastening elements (14, 24) which are positioned in zones (15, 16); which do not coincide with a connecting part (6) of the wear-resistant element (20) or with a connecting part (7) of the stiff top (10).

Description

technical field [0001] The present invention relates to a rapier for a gripper loom, wherein the rapier comprises a gripper belt and a wear-resistant element arranged at the front end of the rapier. In addition, the invention relates to a wear-resistant element for such a rapier and to a gripper loom with such a rapier. Background technique [0002] Regarding gripper looms, also known as rapier looms, the gripper is attached to the front end of the rapier for moving the gripper through the shed. Rapiers for gripper looms typically include either a flexible gripper belt or a relatively rigid gripper belt, also known as a gripper bar. Gripper belts are generally generally made of a reinforced and relatively flexible material, such as epoxy resin with carbon fibers. The front end of the rapier is generally intended to guide the rapier, is usually reinforced and has a rigid design to ensure good guidance of the rapier through the shed. Also, the front end of the rapier is usu...

AI Technical Summary

Problems solved by technology

[0008] The combination of wear elements and gripper straps known from the prior art has the disadvantage that alignment and firmness of the wear elements with the rest of the rapier and more specifically with the gripper straps cannot be ensured

Every known solution always has the risk that during assembly, for example due to careless fastening, dust, defective screws or due to minor deformations, the wear-resistant element will not be properly aligned with respect to the gripper strip

This is especially disadvantageous when the wear element of the rapier can achieve contact with the warp thread or the guide hook, wherein incorrectly aligned wear element, gripper tape, warp thread and / or guide hook can all be damaged
