ABSTRACT:
The invention relates to the textile industry and more particularly to looms. The device comprises a motor-reducing gear unit which can drive the dobby mechanism selectively, through a clutch, this mechanism being normally driven, from the main shaft of the loom by a pulley. A keying system enables the pulley to be made fast to or released from the shaft. The unit can, either drive the dobby mechanism alone for shedding motion searching, or drive the loom and the dobby mechanism for the slow speed operation of the loom. The invention overcomes the drawbacks of pulsed slow speed operation.
