ABSTRACT:
A pilgrim step rolling mill in which a carriage for advancing the product be rolled toward the roller cage is driven intermittently in synchronism with the reciprocation of the roller cage by a screw which is both reciprocated axially and continuously rotated. The carriage advances to drive the product only in response to axial movement of the screw in one direction. The overall mill arrangement reduces the number of and extent of the gearing required.
