ABSTRACT:
A sley drive for a large power loom is comprised of a toggle joint moved by a complementary cam drive and linked on the one hand to the machine frame and on the other hand to the sley support. The toggle joint is folded when the reed beats against the fabric. In order to save space, the complementary cam drive and the toggle joint are arranged below the sley support, and the toggle joint engages the sley support below its pivot point. The arm of the toggle joint linked to the sley support is designed to be foldable about an intermediate pivot point and the pivot point is guided along a cam. The cam is adapted to be turned away from quick shut-down and a shock absorber is moved into engagement with the arm at the point where the toggle point is linked to the sley support.
