Definitions

  • Sheet ROLLER CONSTRUCTIONS FOR ROTARY PERFORATING MACHINES This invention relates to the perforation of sheet material. More particularly it relates to novel apparatus for perforating sheet material and for a process for making such apparatus.
  • the apparatus is intended for making perforations in all types of sheet material such as cardboard, paper, metal, plastics and the like. It is in particular designed for the continuous perforation of paper sheets in, for example, the production of postage stamps, and tickets of all kinds.
  • Such devices have usually comprised a pin roller carrying from ten to twenty thousand perforating pins arranged in a particular pattern with the required spacing desired for the perforations to be obtained and with which cooperates a pin hole roller carrying an equal number of pin holes in a meshing pattern.
  • a pin roller carrying from ten to twenty thousand perforating pins arranged in a particular pattern with the required spacing desired for the perforations to be obtained and with which cooperates a pin hole roller carrying an equal number of pin holes in a meshing pattern.
  • the main object of this invention is to provide rollers for a perforating apparatus in which the problems of matching perforation pins and pin holes as well as of the replacement of broken or bent pins are eliminated.
  • the present invention thus consists in securing around a pin hole cylinder of known construction a sector of a thin sheet or a thin metallic coating and perforating the sheet or coating with the required pin holes by means of the perforating pins of the pin roller.
  • FIG. 1 is a partial cross sectional view of the pin hole roller.
  • FIG. 2 is a partial cross sectional view of the pin roller according to the invention.
  • FIG. 3 is a partial cross sectional view of a sector of the pin hole roller showing the metallic matrix.
  • FIG. 4 is an elevational view showing the cooperation of a pin roller and a pin-hole roller.
  • FIG. 5 is a partial cross sectional view showing a metallic coating on the pin hole roller.
  • a cylinder in particular when it is intended to provide perforations in sheets of postage stamps must have a rather large number of perforating pins of the order of ten to twenty thousand pins and the pin hole roller must have a matching number of holes.
  • Each pin has a diameter which is usually of around 0.9 to 1.0 mm, the pin being inserted in the pin holes by the movements of the cylinders during the perforation process of a sheet placed therebetween.
  • the positioning of the pins with respect to the pin holes had to be strictly coaxial in prior art devices and the diameter of the pin holes could only be from 2 to 3 percent greater than that of the diameter of the pins.
  • a sheet in the form of a sector or of a tube 8 which can be made of steel or other material which is secured by any suitable means on the pin hole roller.
  • holes 9 (H) in the matrix surface 60 of the pin hole cylinder which have a diameter slightly greater than that of the pins P and the holes in which the pins are held and which in any case are not of a critical tolerance.
  • the function of these holes is simply to evacuate paper scrap produced by the perforation process.
  • the metallic sector or tube is secured, the same is perforated by means of the pins of the pin roller when the apparatus is first operated. In this manner there is obtained exact matching between pins and pin holes 80 thus produced in the sheet.
  • the thickness of the sheet used for this purpose is from 0.08 to 0.1 mm. It will be appreciated that this version of the invention cannot employ a continuous sheet element but can only be in the form of a sector.
  • a preferred modification of the invention is employed. This modification consists in placing a thin metallic coating over the pin hole roller, such as by plating or by the use of an anodic or other electrolytic bath or by the deposition of a layer of soft steel.
  • the shaft of the pin hole roller will have a coaxial cavity 10 cooperating with apertures 12 in the body thereof in order to receive paper scrap which will be sucked in by a pipe 11 after traversing opening 12 made in the body of cylinder 13.
  • Securing means for the cylinder indicated by 14 and 17 represent a securing ring for locking in place the pin hole roller.
  • the present invention also provides means for readily replacing pins P which may be broken or used (FIG. 2).
  • the pin roller is made of an outer sleeve 61 and an inner core member of dual sections 20, 30 which are slightly conical in shape. The two sections are secured together by means of bolts 25. On the two halves are mounted two tightening rings 35 for removal purposes.
  • the matrix for the pin hole roller is simply constituted by a rectangular steel sheet 8 which may be secured and turns around a rotating shaft 54 which has locking means in the form of a stop pawl cooperating with teeth on the shaft which are not represented.
  • Sheet 8' is applied against the matrix 60 of the pin hole roller and anchored at one end by means of a small block 57 and a bolt 56 and at the other end 51 by means of a small block 52 and screws 53.
  • Reference No. 9 indicates the suction holes for aspirating the paper scrap. Gripping means shown on the left of the figure serve to apply a sheet of material to be perforated and designated by reference number 59 against the surface of the roller.
  • FIG. 5 is shown in greatly enlarged fashion the matrix M the holes therein H and the electroplated layer which suitably anodically deposited nickel. As can be seen the holes are not entirely filled by the metallic coating. After depositing this coating in any suitable fashion, the surface is ground to give the appearance shown by the dotted lines. The pins P then penetrate the surface to form the perforating holes having the required size.
  • each conical section of the pin cylinder there can be provided a series of openings in each conical section of the pin cylinder.
  • the tightening collars are spaced from the conical elements which are provided with a series ,of holes so that these elements may be turned with respect to the sections to bring the holes therein in coincidence with the pin or pins which it is desired to remove or replace. It is merely necessary to press down on the pin to have it fall into the hole of the conical section which coincides therewith and which communicates with the central cavity in the sections.
  • the same provides an improved pin-hole containing surface for the pin-hole roller in which the conventional pin-hole surface only serves as a sup port for this new surface and has pin holes therein of a larger diameter than the holes on the new matrix and which can be made greater than the diameter of the pin or pin-receiving holes by about 4 to 12 percent.
  • the invention also provides in the pin roller means for easily replacing the pins.
  • a die roller for perforating machines comprising a cylindrical surface provided with bores of a diameter substantially larger than the pins of a pin roller used in conjunction therewith, a layer of electro-deposited metal over said surface covering said bores, said metal layer serving as the die after being pierced by the pins of said pin roller.
  • a roller in accordance with claim I wherein said electrodeposited metal is nickel.
