Abstract: A method and apparatus for performing an order change in a corrugator uses a minimum slit head configuration with all slit heads carried on two sides of a single tool support structure. A single robot is operable on the support structure to independently reset the positions of slit heads during a running order to prepare for subsequent order change in a most efficient manner, utilizing order scheduling that eliminates order changes that cannot be formed with the minimum slit head configuration.

Abstract: A cutting- and creasing -wheel assembly includes a cutting tool, such as a circular disc having a continuous or a serrated cutting edge. The disc is rotatable and supported between a pair of rotatable creasing- wheel halves, the creasing-wheel halves being of equal radial dimension. The disc is controllable for movement between a non-operative position wherein the cutting edge is withdrawn radially inside the outer peripheries of the creasing-wheel halves, and an operative position wherein the cutting edge is projecting radially outside the peripheries. The method of slitting a corrugated or otherwise compressible material involves the provision and control of a cutting tool, preferably a circular disc having a continuous or serrated cutting edge. The disc is arranged to be rotatable and movably supported between a pair of rotatable creasing-wheel halves of equal radial dimension in a cutting- and creasing wheel assembly.
Abstract: A system and method are provided for creating tabs from regular cut-sheet stock after printing by partially punching out a section of a sheet and folding the punched out section back on itself at the remaining side. The location of the punched out section is such that when folded back, a portion of the punched out section sticks out beyond the border of the original paper size. Tab labels may be printed on the back side of the sheet so that when folded out, the tab label is in the correct orientation, i.e., facing front on the folded out tab. The punch head, which is used to punch out the section of the sheet, may be oriented flexibly and moved outboard or inboard. Tabs may be cut and folded to produce a readable set of tabs along any of the top, bottom, lead or trail edges of a sheet.
Abstract: A machine for slitting a metal sheet has a number of knife holder assemblies each containing a rotary knife. The knife holder assemblies are mounted for movement along upper and lower rotating shafts which rotate the knives during a slitting operation. The position of the knife holder assemblies is programmably controlled for efficient and accurate positioning and adjustment of the knives along the rotating shafts for a variety of slitting configurations. Additionally, each of the upper and lower drive shafts contains a pair of drive shaft sections that are normally connected together during operation and can be disconnected for servicing of the knife holder assemblies on the shafts. The slitting machine includes upper and lower frames that are movable relative to each other by adjustment of a pair of jack screws to slit metal sheets of differing thicknesses without labor intensive adjustment or reconfiguration of the machine.

Abstract: There is disclosed a method and apparatus for accurately attaching a die plate to a cylinder segment in a manner that assures accurate registration of two die plates so attached to cylinder segments used in a cutting and creasing machine to cut or crease material passing through a nip formed therebetween. Pins on the arbor in the cutting and creasing machine accurately locate the cylinder segments. A "Make Ready Machine" is used to accurately locate each die plate on a cylinder segment. The "Make Ready Machine" includes axial and circumferential position indicators which are used to accurately place each cylinder segment in a predetermined position when it is mounted in the Make Ready Machine. Once the cylinder segment is in the predetermined position, the die plate is placed on the cylinder segment and moved until each of three lands on the die plate are in proper alignment with a view finder on the Make Ready Machine.
