Abstract

The hub of a supply spool in a cartridge carries a number of ramp surfaces which engage ramp surfaces on the cartridge base. The direction of cam action of the engaged ramps is toward tightening the spool. The amount of tightening torque varies inherently with the weight of the supply spool remaining.
