ABSTRACT:
A spur gear assembly for axially mounting and supporting an end of a feed screw for each carriage and is driven from the main drive, since these feed screws of each carriage are arranged coaxially along a line parallel to a passline of the pilger mill. This spur gear allows relative rotation of the feed screws in this gear assembly mounting and a similar mounting is provided for the other screws of the pair of screws for each carriage. A first gear unit connected to the main drive causes a reciprocation of the stand along with the two feed carriages, and a second gear unit including a shaft clutch assembly is selectively brought into engagement and disengagement with the spur gear assemblies and the first gear unit to impart rotation to the screws to separately and independently advance and return the feed carriages to their starting position while one of the feed carriages continues to advance the shell through the mill.
