摘要

A system is described for cutting and creasing an indefinite weblike material (N) comprising: a first set of creasing tools (15); a second set of creasing tools (17); a first set of cutting tools (31); a second set of cutting tools (33); positioning means (27) for positioning said cutting and creasing tools; and first auxiliary cutting members (63) for making cuts not parallel with the direction of advance of the weblike material for the trims (R) along the edges of the weblike material when the change of job occurs. The first auxiliary cutting members (63) make a joining cut (4, 6) between the cut lines (1, 3) defining the trims (R) of one job and the cut lines (1', 3') defining the trims (R') of the next job, without severing the trims (R, R') transversely where the change of job occurs.
