A rake adjustment mechanism () for at least one of the mountings () and the mounting () for the active blade () has a torque tube linkage mechanism ().

Variable rake shear

A feed roll and stripper assembly for a rolling mill includes at least one feed roll at each of an entry side and an exit side of a pair of work rolls and a stripper at each of the entry and exit side of the pair of work rolls. Each stripper has a stripper tip. At least one of the strippers or feed rolls are adapted to have an adjustable vertical separation from one of the work rolls, according to the direction of movement of material through the work rolls. The vertical separation of the at least one stripper or feed roll from the one work roll on the entry or exit side is different from the vertical separation of the other at least one stripper or the feed roll on the other of the entry or exit side. Each stripper tip is separated from one of the work rolls.
