Definitions

  • ABSTRACT A method and apparatus for piercing thin sheet material, such as plastic film, is provided wherein the sheet material is passed between a piercing member having a plurality of independently resilient protrusions extending therefrom and a backing member having a retiform exterior surface, said piercing member or said backup member being moved relative to the other member, thereby causing said resilient protrusions to follow said retiform surface and selectively pierce said film.
  • FIG. 1 A first figure.
  • the present invention relates to a method and apparatus for piercing thin sheet material and more particularly relates to a method and apparatus for introducing a plurality of small, closely spaced slits in sheet material.
  • film, sheet, membrane or foil refer, unless a specific composition is specified, to any thin, relatively flat self-supporting material such as plastic or rubber film, paper, metal foil, and the like having a thickness of 0.25 to mils.
  • Plastic-backed adhesive bandages have for some time employed a plurality of holes in the portion of the plastic backing adjacent to the absorbent dressing. Such holes provide ventilation to per mit aeration of the wound.
  • small strips of thermoplastic film have been provided on the side of the absorbent dressing which is positioned adjacent to the wound.
  • Absorbent dressings which have traditionally been fibrous materials, tend to stick to a wound upon healing and tearing away such a dressing can reopen a partially healed wound upon removal of the bandage.
  • the use of a thermoplastic film adjacent to the wound greatly decreases the possibility of the bandage sticking to the wound and therefore promotes easy removal of the bandage from the wound.
  • thermoplastic film with apertures very similar to the ventilation holes formed in the plastic backing of the bandage.
  • Perforate dressings of this type are described, for example, in US. Pat. No. 3,543,750.
  • thermoplastic sheet having a plurality of perforations therein.
  • a disposable baby diaper construction which employs, as the layer adjacent to the body of the baby, a thermoplastic film having a plurality of valvular openings therein which permit passage of urine from the baby to an absorbent backing material while retarding flow in the opposite direction. The skin of the baby is thereby kept drier than has heretofore been possible.
  • Each of these methods is subject to one or more disadvantages in use such as wasted material in dye punching and using soluble materials increased processing time in heating or high cost for heating or preforming holes.
  • a method and apparatus for perforating films employing the passage of the film between a piercing member having a plurality of protrusions extending therefrom and a backup member having a retiform exterior surface against which the protrusions are resiliently held.
  • the apparatus of the invention comprises only four basic components: a piercing member, a backup memher, a drive means to impart relative motion between said piercing member and said backup member, and means urging said piercing member and said backup member into adjacency.
  • the backup member should have a retiform exterior surface, which, as used herein and in the appended claims, means that it should have high and low portions or hills and valleys when viewed in cross-section.
  • the surface will be undulant, such as that of a woven wire screen, but to be operative it is necessary only that parts of the surface of the backup member be either higher or lower than the median plane of the surface of the member.
  • the piercing member should comprise a plurality of resilient protrusions such as a comb having a plurality of independently resilient teeth.
  • FIG. 1 is a diagrammatic side elevational view of an apparatus in accordance with the present invention
  • FIG. 2 is a perspective view of the piercing memberbackup member combination of FIG. 1 with the film removed for the purpose of better illustrating the apparatus;
  • FIG. 2a is an enlarged view of section 2a of FIG. 2;
  • FIG. 3 is a perspective view of a film slit by the apparatus of FIG. 1.
  • FIG. 4 is an alternate embodiement wherein the backup member is in the form of an endless belt
  • FIG. 5 is an alternate embodiement wherein the piercing member is in the form of a comb
  • FIG. 6 is an alternate embodiement wherein the piercing member is in the form of a wire brush.
  • thermoplastic film 10 by passing the film between a piercing member 12 and a backup roll 14 which will each be described in greater detail hereinafter.
  • Thermoplastic film 10 may be supplied to the apparatus of the invention directly from an extruder or from a supply roll, not shown.
  • the film is positively carried through the apparatus by being passed between the nip of the backup roll 14, which is driven in a clock-wise direction by a motor 11 through a drive mechanism 13, and a pressure roll 16.
  • a pair of nip rolls 18, 20 and an idler roller 22 control the tension of the films as it is being passed between the piercing member 12 and the backup roll 14.
  • the backup roll 14, in the embodiment of the invention shown in FIGS. 2 and 2a, is a 6 inch diameter steel drum 24 having a stainless steel wire screen 26 encircling the central portion of its outer circumference.
  • the piercing member 12 of FIGS. 2 and 2a is a strip of tempered spring steel having a plurality of parallel slits 28 cut therein to form resilient ribs 30 extending from a continuous steel backbone 32.
  • the backbone 32 is secured in a holder 34 which is supported by the frame (not shown) of the apparatus and is adjustable to control the contact angle and contact pressure between the ribs 30 and the wire screen 26.
  • the retiform surface of the backup member acts as a series of camming tracks for the protrusions of the piercing member.
  • the support for the piercing member is arranged in a manner such that, upon relative longitudinal movement between the piercing member and the backup member, the individual protrusions of the piercing member track the surface of the backup member. Due to their resiliency the protrusions follow the hills and valleys of the backup member exerting greater force against the hills than against the valleys.
  • the film is selectively perforated with the portions of the film covering the hills being perforated while the portions covering the valleys remain unperforated.
  • piercing members useful in the apparatus of the present invention
  • spring steel ribs welded to a backbone, a wire brush 58, as shown in FIG. 6, or even razor blades will be useful in combination with various backup rolls to obtain a variety of perforation patterns.
  • a comb 56, as shown in FIG. 5, comprising a backbone having a plurality of teeth extending therefrom will also be useful.
  • the ends of the ribs or teeth of the piercing member may be sharpened, pointed, flattened, rounded or separated to obtain various piercing effects.
  • the backup roll will also be susceptible to change to accommodate the various types of piercing members and obtain different perforation patterns.
  • the retiform surface may be provided by embossing, etching, knurling or perforating a metal sheet or roll and the backup member may be in the form of a continuous belt 52, as shown in FIG. 4, passing around rollers 48 and 50 rather than the roll described or a screen or metal sheet secured to continuous belt or roll.
  • An apparatus for introducing a plurality of apertures in a film comprising a piercing member having a plurality of independently resilient protrusions extending therefrom, a backup member having a retiform exterior surface constituting camming tracks for said protrusions, support means for said piercing member, means to impart relative motion between said backup member and said piercing member, and means urging said piercing member and said backup member into adjacency thereby causing said protrusions to track in said camming tracks during relative motion between said piercing member and said backup member.
  • said piercing member is a metal strip having a plurality of substantially parallel slits extending from one edge thereof in the direction of the opposite edge thereby defining said protrusions.
  • said backup member is in the form of an endless belt teeth extending therefrom, a backup member which is a wire screen secured to a drum, drive means in combination with said drum to rotate said drum relative to said piercing member, and support means for said piercing member maintaining at least a plurality of the teeth of said piercing member in adjacency with said screen such that said teeth will individually track the undulations of said screen during rotation of said drum and selectively perforate a film positioned on said drum.
  • a method of introducing a plurality of apertures in a film comprising supplying said film to a perforating area, passing said film between the nip of a plurality of resilient teeth and a retiform surface against which said teeth are held in adjacency at said perforating area and moving said film through said perforating area in a manner such that said teeth follow said retiform surface perforating said film when the teeth engage the higher portions of said surface and allowing said film to pass unperforated when the teeth engage the lower portions of said surface.
