Abstract
A cutting device for cutting sheets of material wherein a cutting member co-operates with a bed of upstanding pins which support the sheet. Although the cutting member may be a knife, it is preferably composed of a line of upstanding pins which are sufficiently long to penetrate through the material to be cut and to enter the bed of upstanding pins. The cutting device may comprise two drums mounted for rotation in opposite senses about parallel axes, one drum carrying the cutting member and the other the bed of pins, the tips of the pins being aligned with the cylindrical surface of their associated drum.
