Abstract
A drum comprises a longitudinal central core corresponding to a length of the drum and extending from its ends, end discs, a plurality of intermediary discs provided with notches defining a housing zone of a cutting device and one or several sleeves made of an elastomeric material and braced around the discs. The sleeves at the initial state have a diameter substantially greater than a diameter of the drum and a certain degree of elasticity to deformation. A brace pushes and maintains the sleeves at the bottom of the notches causing an elastic deformation of the sleeves which grip the upper edges of the intermediary discs and an end disc producing pleats between consecutive intermediary discs.
