Abstract
A gripper-loom drawing gripper for receiving a yarn supplied by a yarn feeder and resting on a deflection guide, the gripper serving to position the yarn and carry it into the shed. The drawing gripper is configured to define a longitudinal cavity extending from its forward end facing a filling to be received and positioned by the gripper to its opposed rearward end. The cavity of the gripper faces towards and partially encloses the deflection guide. The forward tip of the gripper includes an inclined surface for guiding a filling to a positioning device on the gripper, and a yarn clamp is also carried by the gripper. The gripper includes additional receiving and positioning devices for a filling to be inserted in the loom shed.
Claims21
A drawing gripper for a rapier loom including elements for receiving and devices for positioning a filling to be inserted into a loom shed, wherein:
- said gripper including walls configured to define a longitudinal cavity extending from its forward end facing its direction of motion when inserting a filling to its opposed rearward end, whereby in use said cavity may face towards and at least partially enclose a loom deflection guide that supports and presents a filling to the gripper during loom operation;
- said gripper is a generally U-shaped plate having a substantially horizontal upper leg and a substantially horizontal lower leg;
- said upper leg which is adapted to be fixable to a rapier band by a support element, is provided with a positioning device adapted for positioning a filling in the form of an inwardly bent lip;
- and
- said lower leg is provided with a second positioning device adapted for positioning a filling at its edge.
A drawing gripper for a rapier loom including elements for receiving and devices for positioning a filling to be inserted into a loom shed, in combination with a deflection guide, wherein:
- said gripper including walls configured to define a longitudinal cavity extending from its forward end facing its direction of motion when inserting a filling to its opposed rearward end, whereby in use said cavity may face towards and at least partially enclose a loom deflection guide that supports and presents a filling to the gripper during loom operation;
- said gripper is a generally U-shaped plate having a substantially horizontal upper leg and a substantially horizontal lower leg;
- said upper leg which is adapted to be fixable to a rapier band by a support element, is provided with a positioning device adapted for positioning a filling in the form of an inwardly bent lip;
- said lower leg is provided with a second positioning device adapted for positioning a filling at its edge;
- and
- said gripper is adapted to be moveable by said rapier band along a guide structure during filling insertion, and said deflection guide is securable to said guide structure.
