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.
