A method for the cutting of block materials, particularly foamed or expanded materials, wherein a knife element having first and second ends is driven in a translatory manner in longitudinal direction so as to perform a reciprocating movement. The driving force is exerted on the first and second end of the knife element, the driving of the first end of the knife element being performed by conversion of a first rotary movement into a first translatory movement, and the driving of the second end of the knife element being performed by conversion of a second rotary movement into a second translatory movement in a sense opposed to that of the first translatory movement.
