ABSTRACT:
A cutting device comprising a support roller (8) freely rotatable in both directions to absorb the pressure of cutting, and a carrier (9) movable in the direction of the longitudinal axis of the support roller (8) on which is fastened a cutting tool (26,27) which can be brought into contact with the roll of material to be cut and present on the support roller (8). The improvement comprises lowering of the cutting tool (26,27) into an operating position, and raising from the operating position, by turning of an eccentric element (14,34) coupled with a pivotable arm (17) holding the cutting tool (26,27). The cutting tool (26,27) is suspended on the arm (17) and thereby limited in regard to its raising and lowering movement. A leaf spring (21) fixed on the arm (17) is braced on the upper end (28) of the cutting tool (26,27) to exert a penetrating force on the cutting tool (26,27) when the arm (17)is lowered.
