Abstract
A thread section of a weft thread is held precisely ready for a receiving rapier in a feed rapier on a rapier loom despite the effects of retarding forces. Deflections of the thread section by the head of a receiving gripper are compensated for, whereby the feed rapier is provided with a thread clamp on the side facing the feed device for the weft thread, which releases on tension forces occurring in the thread section and permits a deflection of the thread section.
Claims15
A transfer gripper for a rapier weaving loom, comprising a base body and at least first and second yarn clamps arranged to retain in readiness relative to the base body a length of a waft yarn to be taken up by a receiving gripper, said length of weft yarn during operation of the transfer gripper extending between the yarn clamps in extended and tensioned condition to enable the respective weft yarn to be taken up by a receiving gripper;
- and further comprising at least one resilient element resiliently yieldable in response to additional tensile force applied to the length of weft yarn to permit deflection of the length of weft yarn between the yarn clamps in response to the additional tensile force while maintaining the length of weft yarn extended in tension between the yarn clamps.
