Abstract
A ribbon loom has a reed drive, a weft-needle drive, an operating needle drive and a shed-forming drive. A main drive shaft carries discs and/or cam discs to which the first-mentioned three drives are directly and articulately coupled. An auxiliary drive shaft extends transverse to the main drive shaft and is connected to the shed-forming drive; it is coupled to the main shaft via a worm transmission the transmission ratio of which can be varied by replacing the worm wheel with a differently dimensioned one.
