Definitions

  • KNIFE CARRIER FOR PAPER CUTTING MACHINES Filed July 12 1930 E a/ 7 a! Patented Jan. 2, 1934 UNITED STATES PATENT OFFICE KNIFE-CARRIER FOR PAPER CUTTING MACHINES Application July 12, 1930. Serial No. 467,435, and in Germany July 16, 1929 2 Claims.
  • This invention has reference to improvements in cutting machines for paper, card board and the like and it relates particularly to machines of this description in which the knife carrier is pro- 5 vided with double face for the mounting of the cutting blades.
  • the knife carrier is provided with the so-called double face structure for the mounting of the knives, inasmuch as by this means the knives or blades may be more advantageously utilized than in the case of knife carriers provided with one operating face only and requiring a considerably wider bearing surface of the knife on its corresponding carrier in view of the fact that the fastening screws cannot be forced sufliciently downwards in order to prevent the head of the screw from projecting beyond the outlines of the knife carrier.
  • Fig. 1 is a sectional view of the knife carrier with a knife secured thereto provided with the improvement according to this invention.
  • Fig. 2 is a front elevation of the device according to Fig. 1, and Fig. 3 illustrates the manner of connecting the invention to the knife carrier.
  • a piece of sheet metal 1 is secured by means of screws 2 to the knife carrier and this plate or sheet 1 is so arranged that its free end will bear against the knife under an angle of for instance at least 40 degrees which is sufiiciently flat to cause the cut off material to be pushed aside without appreciable resistance and without injury to the material.
  • This plate 1 may preferably comprise a piece of-polished sheet of brass which covers up the sockets or holes forthe knife screws 3. But it should be understood that the plate may also be formed of polished steel or the like.
  • the sheet 1 or its attachment is so constructed that the sheet is always applied on the knife and thus assures a good removal ofthe paper.
  • the position of the sheet with a very much ground 01f knife is shown in solid lines, while the dotted lines show the position which the sheet assumes when the knife is not ground down and has, for example, the width shown in dotted lines.
  • the screws 2 which" serve for securing the piece of sheet metal 1 to the knife carrier 4 are engaged with the turnedover edge 2' of the plate 1 which serve for reinforcing the plate 1.
  • the screws 2 may be securely connected to the plate 1 by the turnedover edge, so that they cannot be lost, when the plate is detached.
  • a device of the class described a blade support having a straight face and an inclined face, a blade detachably and interchangeably secured to the straight face of said support, a metal plate secured to the inclined face of said support and said plate cooperating with said blade and being inclined to said blade at any position of said plate.
