Claims7
A picker stick for use in a fly shuttle loom, comprising:
- (a) an elongated main body adapted to swing in the vertical plane of the shuttle motion, the main body having an outside surface which tapers from a larger lower end to a smaller upper end, a bore extending through a substantial portion of the length of the main body is ovate in cross section with the major axis extending in the direction of said plane of the shuttle motion, and
- (b) a body of sound and vibration-absorbing material lying in the bore.
A picker stick for use in a fly shuttle loom, comprising:
- (a) an elongated main body adapted to swing in a vertical plane of the shuttle motion, the main body having an outside surface which tapers evenly from a larger lower end to a smaller end, a bore extending through the main body from one end to the other, and
- (b) a body of foamed polymer of low density completely filling the bore for a substantial length of the bore, thereby providing sound and vibration-absorbing material properties to the picker stick.
A picker stick for use in a fly shuttle loom, comprising:
- (a) an elongated main body adapted to swing in a vertical plane of the shuttle motion, the main body having an outside surface which tapers from a lower end to a smaller end, the outer portions of the body being formed with resin reinforced with fibers which are oriented in spiral paths to resist twisting, a bore extending through the main body from one end to the other, and
- (b) a body of sound and vibration-absorbing material lying in the bore.
