Abstract
An insert rapier includes a weft-holding portion at a bottom portion of a rapier head. Rear and front walls are provided at a distal side of the rapier head with respect to the weft-holding portion and protruding from both sides of the bottom portion, thereby having a warp-dividing function. The insert rapier can guide a weft, which intersects with warps at a predetermined angle, to the weft-holding portion. The rapier head includes a tongue piece provided at the distal side with respect to the weft-holding portion, in a region between the weft-holding portion and the rear wall. The tongue piece has a distal tip located lower than the rear wall, and has an upper ridge gradually ascending from the distal tip toward a proximal side. The tongue piece is movable to a position above the rapier head or toward the proximal side.
Claims14
An insert rapier that is used for a both-side rapier loom and transfers a weft to a carrier rapier, the insert rapier comprising:
- a rapier head having a bottom portion;
- and
- a weft-holding portion provided at the bottom portion of the rapier head,
- wherein the rapier head includes
- hill-like rear and front walls provided at a distal side of the rapier head with respect to the weft-holding portion and protruding upward from both sides of the bottom portion of the rapier head, and
- a tongue piece extending from a position closer to the weft-holding portion than the rear and front walls to a region between the rear and front walls,
- wherein the front and rear walls partly overlap with one another in a side view of the rapier head,
- wherein a distal tip of a distal portion of the tongue piece is located in the overlapping region;
- an upper ridge of the distal portion of the tongue piece gradually ascends from the distal tip of the tongue piece toward a proximal side of the tongue piece;
- and the front wall, the rear wall, and the tongue piece define a warp-dividing portion, and
- wherein the tongue piece of the insert rapier is movable from a standby position to a retracted position, which is above the rapier head or at a distal side of the rapier head, in the side view of the rapier head;
- and the tongue piece is moved to the retracted position before the weft passes the distal tip of the tongue piece.
