Abstract
The bar-pusher actuation device for bar feeders applied to machine tools includes a linear actuator composed of a chain with which the bar-pusher is associated and which is closed around a pair of fixed pinions and a pair of gearwheels which are movable with respect to the pinions. The pair of gearwheels is mounted on a slider which is slidable parallel to the direction of advancement of the bar. The slider is actuated by a jack adapted to perform a reciprocating stroke which substantially corresponds to the length of the portion of bar to be machined.
