  • Patent number: 5511586
    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.

  • Patent number: 5322088
    Abstract: A split loom includes securing elements which can be affixed to a removable loom part to receive the harnesses before separating the removable loom part from a stationary loom part, thereby retaining the harnesses in predetermined positions until re-assembly of the removable loom part to the stationary loom part.

  • Patent number: 5316048
    Abstract: A two-part weaving machine includes lamellar side parts in both portions of the machine frame. The side parts are fitted with mutually associated, essentially horizontal rest surfaces and with mutually associated, essentially vertical stop surfaces. In addition, a tightening system containing tightening wedges is provided for each machine side to press the stop surfaces of the side parts against each other.

  • Patent number: 5307844
    Abstract: A two-part weaving machine includes a stationary machine-frame part containing at least a takeup for winding woven material, and a removable machine-frame part containing at least the bearing for a warp beam. The two machine-frame parts include mutually engaging guides which define a path for constraining the relative motion of the two parts during initial removal of the removable part from the stationary part, and during final re-assembly of the removable part to the stationary part, thus permitting fitting of the two parts together in a compact arrangement without unintentional contact between the respective mechanisms carried by the two parts, and enabling the removal and final re-assembly to be carried out using simple vertical and horizontal movements of the conveyance device.
