Roll-type cutting/scoring apparatus

An apparatus for scoring or cutting, the apparatus comprising:

• a generally stationary frame;
• a lower cradle in the frame;
• a plurality of lower rollers rotatable in the cradle about respective axes and all tangent to a lower imaginary cylinder centered on a lower axis;
• a lower arbor centered on the lower axis and having one end projecting into the frame and an opposite unsupported end;
• a lower journal supporting the one end in the frame;
• a lower tube fitted snugly on and slidably removable from the lower arbor and having an outer surface lying on the lower imaginary cylinder and resting on the lower rollers;
• an upper pressure plate in the frame;
• a plurality of upper rollers rotatable in the pressure plate about respective axes and all tangent to an upper imaginary cylinder centered on an upper axis;
• an upper arbor centered on the upper axis and having one end projecting into the frame and an opposite unsupported end;
• an upper journal supporting the one end of the upper arbor in the frame;
• an upper tube fitted snugly on and slidably removable from the upper arbor and having an outer surface lying on the upper imaginary cylinder and resting on the upper rollers, one of the tubes comprises at least one annular cutting and scoring ridge, the frame comprises an opening defining a window located on a side of the frame facing the unsupported ends of the arbors, the window being larger than the diameter of the tubes to allow withdrawal of tubes axially from the respective arbors;
• means including at least one actuator braced between the frame and the pressure plate for pushing the upper tube downward;
• and
• means connnected to one of the one ends for rotating the respective arbor and tube.
