Abstract
An apparatus for longitudinally slitting and/or grooving material sheets, particularly for sheets of corrugated board, which are being transported through the apparatus. The apparatus includes a plurality of tool members positioned in rows on opposing sheet sides which cooperate in opposing pairs. Each set of rows includes a drive shaft and an adjusting spindle in operable communication with the tool members which include tool body members and which can be conducted within the apparatus along guide rails and can be coupled through controllable couplings to the adjusting spindles. Each tool body member also includes a plurality of tool members where at least one of the tool body members and guide rails are adjustable within the apparatus to position the opposing pair of tool members in the operating positions in engagement with the sheet.
