On Rotary Tool Support Patents (Class 493/367)
  • Patent number: 8267847
    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.

  • Patent number: 7736289
    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 The disc is controllable for movement between a non-operative position wherein the cutting edge is withdrawn radially inside the outer peripheries of the creasing-wheel halves, and an operative position wherein the cutting edge is projecting radially outside the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.

  • Publication number: 20090181839
    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.

  • Patent number: 7134372
    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: A apparatus for manufacturing an object of a folded sheet material has improved slitting, scoring/crushing, gathering, and folding sections or devices. Qualifying means, slitting means, and scoring/crushing means are adjustable with respect to a flat, planer, path of movement so that sheet material moves through the machine without causing the paper to assume an "S" shape, or otherwise suffer loss of paper control. Qualifying means bring within tolerance, sheet which is over thickness. Identifying rollers identify and slightly pre-fold a blank before it enters a gathering and pre-folding section. Novel slitting and scoring heads are easily changed in number or configuration, and have easily replaceable split blades.
