Abstract
The gripper shuttle is constructed of three parts, namely, a metal inner part, a plastics sleeve disposed about the metal inner part, and a yarn clamp having resilient arms within the inner part for engaging a yarn. The metal inner part may be formed with an I-beam cross section or may be of a rectangular cross section with or without a strengthening partition. The metal inner part lends strength to the shuttle, particularly for braking purposes while the plastics sleeve provides a sliding surface for picking.
Claims25
A gripper shuttle for picking in a weaving machine comprising
- a metal inner part having a pair of opposed external surfaces;
- a plastics sleeve disposed about said metal inner part in locked relation and having a pair of opposed wide sidewalls bearing substantially throughout the entire length thereof on said external surfaces of said inner part and a pair of opposed narrow sidewalls, said wide sidewalls having outer sliding surfaces for sliding on a series of guide teeth during picking and for engagement by a catcher during braking;
- and
- a yarn clamp having a pair of resilient arms disposed within said inner part for engaging a yarn.
