US 5,345,977 A · Gripper loom having warp thread bearer members

Abstract

A rapier tape gripper loom having inserter rapier tapes driving inserter and taker gripper heads has the warp threads only provide gripper head support over at least part of the insertion path. The insertion path occupies a width of the shed defined by the path of insertion and retraction of the gripper heads. It is the warp threads of the lower shed which act exclusively as direct support to the gripper heads over the part of the insertion path. During the insertion of the weft yarn, at least one bearer member supports the warp threads alongside of but not in the insertion path. This support effected by the at least one bearer member is outside the insertion path over which the gripper heads travel, leaving the warp threads as adjacently supported by the bearer member as the sole supporting members for the gripper heads.
