ABSTRACT:
An apparatus for driving a carriage of a shuttle in a weaving loom consists of a housing, a driven shaft rotatably mounted in the housing and a driving wheel rotatably mounted in the housing and having an axis of rotation orthogonal to that of the driven shaft. A spool is fixedly mounted on the driven shaft. A wire has an end fixedly attached on the spool and another end connected to a carriage. A plurality of rollers are attached on a circumferential periphery of the driven shaft. One of the rollers is engaged with one of a plurality of guiding channels defined on a circumferential periphery of the driving wheel. The guiding channels are so configured that when the driving wheel rotates, the driven shaft can repeatedly have the following modes of movement: firstly remaining in a static state, rotating and accelerating in a first direction, decelerating, staying in another static state, rotating and accelerating in a second direction, decelerating, and finally returning to the first static state.
