To obtain a large number, in excess of 1000, of different speeds for a thread carriage driven by the warp cylinder of a sectional warping machine a multi-speed gear transmission is provided which has two gear mechanisms, each with several gear ratios, interposed between drive input and output shafts of the transmission, the two gear mechanisms being mechanically connected in parallel with the drive input shaft and driving respective crown wheels of a differential gear the planet carrier or spider of which is in turn mechanically coupled to the transmission output shaft. |
