Abstract
A tappet-shedding mechanism having a reduction gear driven from the crankshaft to a tappet, and operated by a key-clutch device under the control of a card cylinder selector device via two control levers, one of them working in conjunction with a fulcrum shaft which reciprocates synchronously with the shedding action. A synchronously operating push rod blocks the movement of the non-operating control lever. The selector device operates, like dobby mechanisms, over a two-pick cycle, permitting increased loom speeds without loss of accuracy and reliability in the shedding motion.
