Abstract: A heald rod retention device for a jacquard system includes a mounting frame encasing a ferromagnet, a pair of retention plates pivotably mounted on the frame, each retention plate encasing coils and defining a lower hooked end, and two springs mounted on the frame. The springs respectively exert a laterally pushing force of the retention plates so that the lower hooked ends thereof are forced to move toward each other. A pair of heald rods are slideably mounted on the frame and respectively define upper hooked ends which are engaged with the lower hooked ends when the coils are energized and separated therefrom when the coils are not energized. Each heald rod further defines a protrusion for contact with a knife bar. A rope-pulley system is provided for connection with the heald rods and a jacquard needle.

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 loom heald hook lifter includes a horizontal bracket, a plurality of links secured to the horizontal bracket so that the links are not pivotable relative to the horizontal bracket, and a corresponding number of blades each pivotably linked to one of the links. A first hole is defined through a lower tip of each of the links and a second hole is defined in an edge of each of the blades. The blades are respectively pivotally connected to the links by a corresponding number of pintles loosely extending through the holes in the links and frictionally engaging the holes in the blades.
