Abstract
A transmission for the shedding mechanism (dobby) of a loom in order to produce a non-uniform drive from a uniform drive, having a drive shaft and a driven shaft aligned therewith, said shafts being mounted in a transmission housing. In order to simplify the construction, a rotor is arranged fixed for rotation on the drive shaft, the rotor bearing at least one gear segment which is swingably supported on an eccentric shaft and has two cam rollers arranged in different planes, the gear segment being in engagement with a driven pinion arranged fixed for rotation on the driven shaft and the cam rollers cooperating in force-actuated and/or form-locked manner with two cams fastened in different planes to the transmission housing, the asymmetry of which cams producing a relative movement per revolution between the drive shaft and the driven shaft. The relative movement per revolution can be adjusted by replacing the two cams. The rotor can also be formed with two arms and carry two gear segments, the cam rollers of which cooperate with the two cams.
