Definitions

  • the invention concerns an apparatus for continuously perforating photographic films, papers, magnetic tapes or the like which apparatus includes a rotary roller on which a band of film runs in the same direction and is at the same time perforated by means of punches.
  • the punches are seated at the end of levers or plate springs which are arranged on the periphery of the rotary rollers and actuated by two oblique or eccentric rings which surround the periphery of the roller from the side, the punches describing the arc of a circle. Owing to the circular are over which the punches move, they do not dip accurately into the die apertures so that accurate perforation cannot be ensured. Furthermore, owing to the necessarily small amount of play between the punch and the die the punch cannot go deeper than the thickness of the film. Any drag on the end surface of the punch or on the roller die makes this apparatus useless.
  • a roller punch is in engagement with a roller die by an amount corresponding to the thickness of the film, and the film is perforated as it runs between the rollers rotating in opposite senses and is at the same time conveyed. Owing to the movement of the rollers, the quality of the perforations are. poor and the tolerances of form are not adequately maintained. As the diameter and hence the distribution of apertures on the die roller is altered by grinding the roller to sharpen it, the tool soon becomes useless. Furthermore, it is not easy to carry out a subsequent adjustment of the punch roller and to grind it.
  • the perforations produced are very accurate owing to the fact that the perforating punches dip in a straight line into the band die and pass through the film which is covered without contact, and owing to the fact that the band die is firmly held against the surface of the roller by means of the link members. It is particularly advantageous that the film, guided by the punches inserted in it, is conveyed smoothly and is not released until other punches have taken over the function of guiding. Owing to the fact that a large number of punches are in operation, the acceleration of the punches and the wear on the tools are only slight even at a high output of about 150 m./ min. When the band die with the link members has 3,171,314 Patented Mar.
  • the punches can be sharpened at their ends while the tool is rotating, no difficult dismantling and adjustment being necessary. This sharpening process does not affect the spacing of the perforations.
  • the band die with the link members can be made simply and inexpensively by a special punching and calibrating process and is easily replaced, the open anchoring members being removable without any special tools and the die can be used again and again.
  • FIG. 1 shows a perforated film strip
  • FIG. 2 is an overall view of the whole perforating apparatus and indicates diagrammatically the manufacturing process for perforating the film shown in FIG. 1.
  • FIG. 3 is a front view of the punching roller with the band die, shown partly in section.
  • FIG. 4 is a side view of the punching roller and band die along the line A-B in FIG. 3, with the cover of the framework half removed and parts of the punches visible.
  • FIG. 5 is a partial view in perspective of an anchoring member fitted into the band die.
  • FIG. 6 is a section through the punch guide after the punch has passed through the film and the band die.
  • the rotatable perforating apparatus shown in FIG. 2 consists of the punch roller 1 and the endless band die 2 moving over the Wheels 3 and 4.
  • This band die is fixed by a part of the punch and covers approximately one quarter of the surface of the punch roller 1.
  • the drive is provided by the motor 5 and transmitted to the chain wheel 8 through the chain wheel 6 and the roller chain 7.
  • the chain wheel 9 is rigidly connected to the axle of the chain wheel 8 and moves the band die forwards by way of the roller chain 10 and the chain wheels 11 and 12.
  • the chain wheel 13 which Winds the film by way of the roller chain 14 and the chain wheel 15 is mounted on the shaft of the chain wheel 12 and the wheel 3.
  • the unperforated film is unwound from a feed roll 17 by the punch roller 1, which is in engagement with the band die 2, the film passing over the deflecting roller 18 on its way to the punch roller.
  • the perforated film is then wound on the roll 19.
  • a roller 20 is provided to enable the band die to be lifted from roller 1 more easily.
  • a ball bearing 24 secured by a locking ring 22 and a disc 23 is mounted without play on an attachment situated concentrically on the shaft 21.
  • the cover 25 of the framework is rotatably mounted on this ball bearing and is fitted to the outer ring of the ball hearing by means of the threaded cover 26.
  • a closure ring 28 which is connected to the cover 25 by the countersunk screws 27 is attached to a guide ring 29 for the punches by countersunk screws 30.
  • An oil ring 31 and a sealing ring 32 are mounted partly in the guide ring 29 and partly in the closure ring 28.
  • the punches 34 slide in the guide ring 29 to which the spool member 33 is also connected.
  • the rounded ends of the punches are guided in a groove and supported by an eccentric ring 35.
  • the eccentric ring 35 is mounted on two ball bearings 36 which are fitted without play on an attachment eccentrically of the shaft 21 and secured by locking rings 37 and 38.
  • a grooved ring 39 is attached to the eccentric ring 35 by countersunk scews 40.
  • the punches 34 are guided by the grooved ring 39 and are prevented from falling out by a wire ring 41 on which all the punches are threaded and which, as shown in FIG. 4, lies in the groove between the ring 39 and the ring 35.
  • the housing cover 42 is mounted concentrically on the shaft 21 with the aid of the ball bearings 43 which are free from play and it is secured by the nut 44 with two holes.
  • Slip rings 45 which are insulated from one another, and the chain Wheel 9 are connected to the cover42 by countersunk screw 46.
  • Carbon brushes 47 sliding on the slip rings 45 supply current to the spool member 33.
  • the dash-dotted line with the points of three arrows indicates the direction of the magnetic flux when current flows through the spool.
  • the endless band die 48 which is prefeably a band of spring steel with great surface hardness, is provided with cut apertures for the passage of the punches 34 and, on each side, locking slots in which the projections of the anchoring member 49 are guided.
  • the band die 48 is bent transversely and the projections on the anchoring member are pushed into the slots so that in the process of elastic recoil the inner edges of the slots on the band die jump into the grooves of the anchoring member 49, as shown in FIG. 5.
  • the interruptions in the anchoring member 49 are slightly larger than the cut apertures in the band die 48 so that a good cut edge is formed and the waste material 50 cut away by punching can easily drop out.
  • the film 51 is guided in a path and covered without contact by the band die 48.
  • FIG. 4 shows the band die 48 with the anchoring members 49 opened up, during the perforating process.
  • the punches 34 enter the anchor members 49, ascending continuously through the film 51 and the band die 48.
  • the anchoring members are segments cut from a turned ring. The side of the segments facing the band die correspond in dimensions to the external radius of the band die 48 lying on them.
  • the anchoring members 49 are chamfered on their long sides.
  • the circumferential surface of the disc 4 has two slots 52 through which the punch waste 50 is removedby suction from the anchoring members as the die passes over the slots, and the waste is then conveyed to the outside through the hollow shaft. described with reference to FIGS. 1 to 6 operates as follows:
  • the unperforated film 16 pulled by hand from the feed roll 17 is placed round the deflecting roller 18 and is pushed over the guide path of the punch roller 1 and under the band die 2.
  • the apparatus controlled by the eccentric ring rotating with the apparatus continuously slide outwardly, ascending in the radial direction. During this movement, they pierce the film 51 and the band die 48 and push the waste material 50, as shown in FIG. 6, into the apertures in the anchoring members, from which the waste is then removed by suction in the wheel 3.
  • the punches are then returned to their starting position by the movement of the eccentric ring 35 with which they are connected by the wire ring 41.,
  • the chain wheel 6 transmits the drive through the roller chain 7 to the punch die 1 and to the chain wheel 9 and the roller chain 10, the chain wheels 11 and 12 being thereby driven.
  • the band die is carried without tension by the punches of the punch roller 1, which are in engagement with the band die, and by the discs 3 and 4.
  • the film which is guided without contact between the band die and the punch roller, has been perforated it is moved forwards by the punches that are in engagement with it. It passes over the deflecting roller 18 to be wound up on the roll 19 which is driven by the chain wheel 13, the roller chain 14 and the chain wheel 15. Any number of perforation rows spaced at any distance apart may be provided.
  • the perforating apparatus may be used in the light if suitable covering means are provided.
