Abstract: A weaving loom has a transmission, which includes a driving wheel, a driven wheel, an endless driving belt that extends around the driving wheel and the driven wheel, and at least one magnet unit, which is secured to an inside surface of the belt for attracting and driving a shuttle to circulate on a machine frame inside the belt.

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.

Abstract: A weaving loom with a magnetic shuttle comprised of an endless loop for guiding the shuttle to circulate and fly through the shed of warp and a magnetic means constructed as a structure which generates a magnetic force circulating along the endless loop for attracting and driving the shuttle.
