Abstract
A multi-cylinder module has a common block within which the cylinders are formed and having a piston disposed within each cylinder and an output rod connected to each piston. Pressurized air acts on the piston against the bias of a corresponding spring to drive the respective rod outwardly from the module. Each rod has a coupling member which is coupled to the gate of a hook of a tufting machine having gated hooks for forming both loop and cut pile. The modules are mounted directly to the hook bar of the tufting machine and require no additional linkages between the coupling and the gate with the inherent lost motion and other inefficiencies associated with such additional linkages.
