ABSTRACT:
A handling unit for axially transporting elongated objects from a first location to a second location such as from a feed table into a machining unit where machining operations are to be performed upon the object. A feed table, or corresponding depository, supports a plurality of the objects to be transported in parallel relationship, and provision is made to advance the objects so that a single object is placed in a pickup location. An axially movable push rod then engages the end of the object when desired to accomplish the axial transport. This push rod is operated by a rod-less cylinder such that the cylinder and the push rod are in parallel alignment thereby reducing the length of the device to the length of the cylinder. Various embodiments are described, together with that of an "unloader" to receive the objects after machining and place them on a receiving table or the like.
