Abstract
A roll stand assembly for processing a sheet product with a plurality of rolls on a frame. A first roll has a first sheet engaging surface and a first shaft assembly. A second roll has a second sheet engaging surface and a second shaft assembly. The first and second rolls are relatively movable between: a) an operating relationship; and b) an open relationship. A safety assembly prevents inadvertent changing of the first and second rolls from the open relationship into the operating relationship. The safety assembly includes a first chuck component mounted for movement relative to the frame between: a) a running position wherein the safety assembly is in a disengaged state; and b) a lockout position.
