Abstract:
In a selvage forming device for a power loom having a main drive system wherein the selvage forming device includes yarn guide structures movably guided for mutually opposing motions to raise and lower at least two selvage yarns to sequentially form selvage sheds and to periodically cause at least one selvage yarn to periodically cross at least one other selvage yarn in a direction transversely of the raising and lowering direction, the improvement comprising:a selvage drive motor;a selvage drive arrangement connected to the yarn guide structures and when actuated driving the structures to periodically raise and lower them with mutually opposing motions and, during such raising and lowering, causing at least one selvage yarn to periodically cross at least one other selvage yarn in a direction transversely of the raising and lowering direction;said drive arrangement including eccentric drives connected between said selvage drive motor and the yarn guide structures;said selvage drive motor being independently controllable to vary the motion of the eccentric drives and the yarn guide structures.
