ABSTRACT:
A drive device for clamp holder carriages of a continuously operating pilger rolling mill, comprising two carriages sliding on slides parallel to the rolling axis. Each carriage is coupled to a screw threaded rod, rotation of which causes movement of the carriage, each rod being provided with an axially movable nut held from rotation. A push rod is supported on the nuts to move the nuts and the screws in the rolling direction, each of the screws being rotatable in driving directions towards and away from the rolling mill so as to permit the return of one clamp holder carriage while the other feeds stock to the mill.
