Abstract
A pinch roll and shear combination for use in a mill, such as a reversing hot strip mill. The pinch roll and shear combination includes a stationary frame provided with a rotatably mounted lower roll and stationary lower blade adjacent the lower roll. A rectilinearly movable carriage is mounted on the frame with a piston for moving the carriage. An upper roll is rotatably mounted on the carriage and cooperates with the lower roll to form a pinch roll. An upper blade assembly is mounted on the carriage and cooperates with the lower blade to form a shear.

A pinch roll and shear combination comprising:
- a frame;
- a lower roll rotatably mounted on said frame;
- a lower blade mounted on said frame adjacent said lower roll;
- a movable carriage mounted on said frame;
- a means for moving said carriage;
- an upper roll rotatably mounted on said carriage and cooperating with said lower roll to form a pinch roll;
- and
- an upper blade assembly mounted on said carriage, wherein said upper blade assembly cooperates with said lower blade for form a shear and wherein said upper blade assembly is mounted for movement relative to said carriage.
