摘要

A bar stock loader (10) having a synchronizing head (16) for matching the flats of a fresh length of bar stock (14) with the flats of a remnent of bar stock (14') being machined in an automatic screw machine (12). The synchronizing head (16) has a selectively engageable drive controlled by a timing signal (66) that allows the fresh length of a bar stock (14) to be rotated at a speed approximately the speed of rotation of the remnant segment of bar stock (14'). A clutch (30) is provided for selectively interlocking a driven member (22) having a bushing (24) in which the fresh length of bar stock (14) is received to a bar stock engaging member (23) that is connected to the spindle (28) of the automatic screw machine. A method of loading bar stock is also disclosed.
