ABSTRACT:
A method of conveying sheets of e.g. corrugated cardboard through a processing machine, comprising a feed-in unit and units for carrying out printing, punching, slotting etc. of the sheet, in which the sheet is gripped between a belt with a flat gripping surface and a belt with a non-planar gripping surface disposed at a distance from each other, which distance is smaller than the thickness of the sheet, so that the non-planar belt clamps the sheet securely against the flat belt while deforming the sheet. Apparatus for carrying out said method has conveyor and support means for the sheet. The conveyor means has two cooperating belts one of which is a flat toothed belt running over two deflecting rollers one of which is forcibly driven. The second conveyor belt is non-planar and disposed at a distance smaller than the thickness of the sheet from the flat belt and runs over freely journalled deflecting and supporting rollers which oppose the corresponding rollers for the flat belt.
