Let-off warp beam coupling device

摘要

The let-off warp beam coupling device has a let-off warp beam rotatably and detachably mounted on a specified position of a weaving machine and a beam gear provided on the weaving machine so as to be opposite to a shaft end of a beam shaft of the let-off warp beam for rotating the let-off warp beam. A driven coupling member is provided so as to be secured at the shaft end of the beam shaft of the let-off warp beam, and has a plurality of projections provided on a circle positioned on a plane perpendicular to the axial direction of the beam shaft. Each projection projects in the axial direction of the beam shaft and has a side face tapered in the axial direction. A driving coupling member is also provided on the beam gear side so as to be opposite to the driven coupling member with a specified spacing therebetween. It has a plurality of projections provided on a circle positioned on a plane perpendicular to the axial direction of the beam shaft.
