ABSTRACT:
The invention refers to the devices for dividing a continuous web of wrapping material into successive single sections of a same length. These devices comprise a rotary cutting roller (1) with one or more angularly equispaced peripheral radial blades (7), the cutting edge of which is parallel to the axis of shaft (6) for driving in rotation the said cutting roller (1), and a rotary counter-roller (19) having one or more peripheral anvils (18) that cooperate each with a blade (7) on the cutting roller (1). According to the invention, the blade or blades (7) are each secured to a projecting blade-carrying member (8) which by elastic deformation is elastically yieldable in the radial direction toward the axis of shaft (6) for driving in rotation the cutting roller (1).
