Abstract
A device for affixing a shaft drive element to a loom warp beam shaft includes a clamping element having teeth, teeth at one end of the drive shaft and teeth on the drive element, and a displacement mechanism for sliding the clamping element and drive element on the drive shaft such that the clamping element teeth and the drive element teeth engage the drive shaft teeth. Upon sliding the drive and clamping elements over the drive shaft, the clamping and drive element teeth and the shaft teeth are mutually rotated to cause oppositely facing flanks on the drive and clamping element teeth to be pressed against corresponding flanks on the drive shaft teeth and thereby prevent relative rotation.
Claims13
An arrangement for driving a warp beam, said arrangement including a warp beam shaft having teeth, a warp beam drive element having teeth, and warp beam drive means for driving the drive element, the teeth on the warp beam shaft and the teeth on the drive element each having tooth flanks, said arrangement further comprising:
- a clamping element;
- and
- means for causing the drive element and the warp beam shaft to rotate relative to each other such that the tooth flanks of the drive element teeth and the tooth flanks of the warp beam shaft teeth are pressed and held against each other to prevent relative movement between the drive element and the warp beam after the drive element has been placed on the warp beam drive shaft.
