Abstract

A device for making cuts in the direction of the advance of pieces of thin material, for example in slips of paper along the path on which they are fed, includes a cutter carrying drum (1) and a cutting bed drum (2) rotating in opposite directions to each other. The drum (1) carries at least one peripheral cutter (3, 3', 3') whose cutting edge (103) is orientated in the direction of advance of the pieces of material and is curved coaxially with the drum (1), projecting radially beyond it. The cutter (3, 3', 3') is fixed on the cutter carrying drum (1) by a removable (5, 7) base (4, 4', 4') which has an intrinsic elasticity provided by slits such that it provides a certain spring support of the cutter (3, 3', 3') alternatively and in combination in the radial direction and in the direction of oscillation about an axis transverse to the cutting edge (103) of the cutter (3, 3', 3'), in particular substantially parallel to the axis of the drum (1).
