ABSTRACT:
Products (2) made of paper or similar materials are cut along predetermined cutting lines in a drawing cut between crossed knife edges while being conveyed continuously in a dense conveying stream in which their main surfaces are orientated substantially perpendicular to the conveying direction (v). For this purpose a counter knife (1) with a guide edge (11) is allocated to each product (2) and the products (2) together with the counter knives (1) are conveyed past at least one cutting knife (5) with a cutting edge (51) having two ends, whereby the cutting edge (51) of the cutting knife (5) substantially lies in the plain formed by the guide edges (11) of the counter knives (1) and forms a cutting angle (.alpha.) with the guide edges (11). While the cutting edge (51) forms a cutting formation with one guide edge (11) in which cutting operation the two edges are intersecting in a cutting area (4) being shifted along the cutting line, the cutting knife (5) is additionally drawn in a direction (Z) parallel to the guide edge (11) or along the cutting edge (Z') or in a direction lying in between said two direction and opposed to the direction in which the cutting area (4) is shifted. Between successive cutting operation with successive counter knives (1), the cutting knife (5) is reset (R, R') in an direction opposed to the direction of the drawing movement (Z, Z').
