Abstract
A cutting arrangement for a material web, especially photographic copy material in a photographic copier includes a knife roller (,) and a drive (,to,) for reciprocating the knife roller (,) between two turnaround positions (S,, S,) transverse to the material web (M) to be cut, to thereby carry out one cut respectively. At least two starting positions (S,, S,or S,, S,) are provided for each of the two cutting directions which are associated with different widths of the material web (M). The drive (,to,) commences the cutting movement of the knife roller (,) respectively at that starting position (S,, S,or S,, S,) associated for one cutting direction with the respective material web width and moves the knife roller (,) after completion of the cut to the respectively closest turnaround position (S,, S,) and from thereback to the starting position (S,, S,or S,, S,) associated for the other cutting direction with the respective material web width, provided that the latter starting position (S,, S,or S,, S,) does not coincide with a turnaround position (S,, S,). The arrangement of different starting positions for material webs of different width makes time savings of up to over 50% possible.
