ABSTRACT:
A cutting blade is mounted on a support by being clamped between a supporting portion of the support and a pressing portion of a pressing lever which is mounted on the support for pivoting about an axis which extends parallel to the elongation of the cutting blade and has an actuating portion which is acted upon by at least one actuator which urges the pressing lever towards its clamping position. A resilient mounting portion is connected to the support and to the pressing lever and mounts the pressing lever for the abovementioned pivoting. The mounting portion has enlarged foot and connecting zones which are respectively received and held in respective compatible recesses of the support and of the pressing lever, preferably in undercut grooves thereof. A part of the support, the pressing lever, the mounting portion and the actuator may constitute a unit which is interchangeably mounted on the remainder of the support. Additional such units may also be provided, being arranged adjacent and with spacing from the abovementioned unit and constituting the outer periphery of a cutting tool which may be mounted for rotation about an axis parallel to the elongation of the respective cutting blades.
