摘要： A device for processing a continuous web for absorbent articles, comprising a cutting means (2), which rotates about its axis of rotation (2a), and an opposing means (3), which rotates about its axis of rotation (3a); the cutting means (2) has a plurality of cutting elements (4) and the opposing means (3) has a plurality of anvils (5) each intended to operate in conjunction with a cutting element (4) to cut the continuous web (19) into respective separate pieces (29); during the rotation of the cutting elements (4) about the axis of rotation (2a) of the cutting means (2), the cutting edge of each blade (6) defines a frustoconical trajectory (24); during the rotation of the anvil (5) about the axis of rotation (3a) of the opposing means (3), the opposing surface (7) of each anvil (5) defines a frustoconical trajectory (25); the frustoconical trajectory (24) defined by the blades (6) of the cutting elements (4) and the frustoconical trajectory (25) defined by the anvil (5) have a line of tangency (27) in common between the two frustoconical trajectories (24; 25) along which each cutting element (4) contacts an anvil (5) to cut the continuous web, thus defining a cutting station (17) where the continuous web (19) is cut.
