Abstract (en)
A cutting device is provided for slitting a web of plastics material which is continuously moving between first (3) and second (4) transfer rolls rotating about horizontal axes while being kept under mechanical tension between said rolls, the device including a knife (6) with a circular cutting edge (6B) composed of a thin disc with a bevelled edge (6D,6E) which is slowly driven in rotation about an axis substantially parallel to the axis of said transfer rolls (3,4) and which, in the cutting position, intersects from below, and over a circular segment, the oblique plane inclined at substantially 45 DEG to the horizontal formed by said web between said rolls, the direction of rotation of said disc (6) being such that the tangential movement of the cutting edge (6D,6E) thereof in the region that intersects said web is in the opposite direction to the movement of said web. <IMAGE>
