A tufting machine configured to provide needles co-linearly along a tufting plane from opposing needle holders provided in a needle module. The needle holders may be selectively latched with latch pins connected to limbs extending from a yoke connected to the push rod of the tufting machine. The needle holders are biased in a dis-engaged position with compression springs which extend between caps on the needle holders and a guide plate which locates the needle holders laterally while spacing the opposed needle holders from one another.

Inline needle tufting machine with needle modules

A tufting machine has a yarn feed roller assembly with a plurality of rotatable driver rollers driven at different speeds and a plurality of actuators in the form of a pivotable arm having in one embodiment a pair of yarn feed reels one of which is arranged to selectively press yarn into engagement with one of the drive rollers and the other arranged to selectively press yarn into engagement with another drive roller. Yarn is engaged by each actuator and a selected drive roller for a period of time determined by a pattern. The longer the actuator engages the high speed roller during the stroke of a tufting machine needle the greater will be the pile height of the tufts produced and alternatively the longer the actuator engages the lower speed roller during the needle stroke the lower will be the pile height. Pile height variations between a high pile and a low pile may be obtained by controlling the proportion of time during the stroke that the yarn engages with the high and low speed rollers.

Yarn feed for assembly for a tufting machine

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.
