PROCESSING APPARATUS FOR CORRUGATED CARDBOARD SHEET

PROBLEM TO BE SOLVED: To provide a new processing apparatus for a corrugated cardboard sheet which enables the shortening of the setup time needed for changing the space of two slitters or the position of one in the grade change of the corrugated cardboard sheet and which improves the accuracy of positioning the slitters. SOLUTION: The processing apparatus is furnished with transferring means 8, 9 that transfer a corrugated cardboard sheet W to the downstream side, a tool attaching block capable of free ascent and descent, a compressing tool 12 attached to this tool attaching block, a first and a second slitter 13, 14 that are supported by the tool attaching block, receiving jigs 47, 48 in which cutter receiving spaces are formed, the spaces in which the lower edges of the cutters are each positioned when the first and second slitters 13, 14 descend, and a moving mechanism to move respectively the first and second slitters 13, 14 to the longitudinal direction of the compressing tool 12. The moving mechanism includes driving means 126, 127 which move the first and second slitters 13, 14 respectively and a control means to control these. COPYRIGHT: (C)2009,JPO&INPIT
