Abstract (en)
[origin: WO2005021265A2] The invention relates to a method and a sheet offset printing machine (2) for printing a stock in the form of individual sheets (1) and for punching blanks (3) into sheets (1) in a printing or painting group (14) of the printing machine (2) comprising a rubber or fabric varnishing cylinder (22) and a counterpressure cylinder (24) determining a gap (34) for the sheets (1) passing through, wherein one of cylinders (22) comprises a punching sheet (36) provided with salient punching burrs (44) on the external surface thereof. Said printing or painting group (14) also comprises a suction device (40) for sucking off punchings (38) produced by punching (3) during passage through the gap (34). The aim of said invention is to avoid that the sheets (1) take off from the other cylinder (24) by depression produced during suction. For this purpose, the punching sheet (36) is provided with projected spring clips (68) on the periphery of the rubber or fabric varnishing cylinder (22) which press the sheets (1) against the external surface (52) of the other cylinder (24) in the area of the gap (34).
