Abstract
The invention provides a rotary cutter drum for use in apparatus for cutting continuous web material into discrete lengths in which the polar moment of inertia is kept to a minimum. The drum consists of a prefabricated metal load bearing member to which a block, on which a knife blade is mounted, and a balancing member are secured. The load bearing member, the block and the balancing member are then covered in a light-weight material such as an integral skin polyurethane rigid foam material arranged so that the outer surface of the whole drum is rotational symmetrical, the surface being interrupted to allow for the mounting of the knife blade.
