Definitions

  • Tapes of various kinds are in widespread use as 1. reinforcement or closure means for containers, particularly those of paperboard or corrugated board type, wherein the tape is employed to retain closure flaps in closed position, and 2. as opening means for such containers, wherein the tape is appropriately positioned on the container and employed as a tear strip.
  • Such tapes must possess adequate strength for the purpose and must also incorporate therein an adhesive layer to provide an effective bond to the container wall surface. lt is, of course, desirable that, for practical use of such a tape, its cost of manufacture be as low as possible and that it be capable of application in a convenient and trouble-free manner.
  • tapes of satisfactory strength are usually of such relatively high cost that their use is restricted to special circumstances.
  • the step of applying the tape is frequently attended by difficulties such as troublesome transfer of adhesive from the adhesive layer to surfaces of the applicator or the like.
  • An essential feature of the tape in accordance with the present invention is that it has a longitudinally extending surface coating section that has a surface contact adhesion characteristic at temperatures at which the remaining coating section is heat stable.
  • Such surface contact adhesion characteristic is not of pressure sensitive type but rather requires the application of heat to render the surface coating section adhesive when applied to another surface.
  • Such a tape may be applied by an applicator having a heated surface arranged to soften only the one coating section whereby when such coating section of the tape is engaged with another surface the tape will be adhesively applied to such other surface.
  • the tape applicator ofthe present invention broadly comprises a roller, a heating element in the roller for heating the peripheral surface thereof, and means for directing a length of tape onto the peripheral surface of the roller.
  • the invention also resides in a method of applying the tape of the invention to sheet material which comprises applying heat to the heat-stable section of the tape for transmission through the tape to the adhesive section and softening thereof, and then applying the heat-softened section to the sheet material.
  • FIG. l is a cross section, on a greatly enlarged scale, of a tape in accordance with the invention.
  • FIG. 2 is a partial edge elevation ofthe tape of FIG. 1,
  • FIG. 3 is a cross section, also on an enlarged scale, of a modified form of tape
  • FIG 4 is a side elevation of a tape applying device
  • FIG. 5 is an end elevation, partly in section, of the device of FIG. 4.
  • FIGS. l and 2 indicates a tape in accordance with the invention which comprises two layers l1 and l2.
  • Layer 1l comprises a plurality of elongated fibrous threads or strands or filaments 13.
  • Filaments 13 extend longitudinally of thc tupe and may be of cotton, rayon, polyester, polyamide,
  • Hot-melt adhesives are now recognized as a specific class of adhesives. They may comprise a low molecular weight natural or synthetic wax or resin, such as coumarone-indene resins; mineral, vegetable and petroleum waxes; alkyds; terpene and phenol-formaldehyde resins. This low molecular weight base material is reinforced and strengthened with a high molecular weight polymer such as ethyl cellulose, polyvinyl acetate, polyethylene, polystyrene, polyamide and the like. They are heat-stable at temperatures below about F. and soften to an adhesive consistency at temperatures of about 250-350 F.
  • a strand of strip composed of rows of filaments 43 are arranged in tape configuration with the individual filaments in substantially directed contact with adjoining filaments.
  • a heat barrier coating or layer 44 is applied directly to one side surface of the strip, such coating being adhered directly to the filaments which become partially embedded therein.
  • the coating may be composed of any suitable heat-stable composition, such as that employed in layer l1 of FIG. l.
  • a hot-melt adhesive coating or layer 45 is applied directly to the other side surface of the strip, such coating being also adhered directly to the filaments which become partially em bedded therein.
  • the applicator shown comprises supporting frame generally indicated at I4 which may be mounted for adjustable sliding movement, by means of a guide l5, on a horizontal rail 16. As shown, adjustment may be effected by a rack 17 on the rail, a gear 18 meshing with the rack and fixed to a shaft 19 journaled in the guide and driven by a hand wheel 20.
  • a plate 21 fixed to the guide 15 has pivoted thereto at 22 an arm 23. Fixed to the free end portion of arm 23 is a spindle 24 on which is journaled a free-running roller 25. Roller 25 has a smooth peripheral surface 26 which is heated in any suitable manner.
  • the heating means comprises an electrical resistance element 27 housed in a chamber 28 adjoining the peripheral wall 29.
  • Power supply means for the element includes a cable 30 connected to a power source, a connector 31 having a pair of brushes 32 in contact with a pair of contact rings 33 carried by the roller hub 34, and connections (not shown) connecting the rings 33 with the resistance element.
  • the roller through its peripheral surface 26, is arranged to rest upon a sheet 35 of corrugated board, paperboard or the like (for subsequent use as a container wall), such sheet 35 being disposed upon any suitable supporting surface 36.
  • the sheet 35 is adapted to be moved along the surface 36 in any suitable manner in the direction of the arrow, such movement resulting in rotation of the roller 25.
  • the pressure exerted by the roller on the sheet 35 may be adjustably controlled by means of an adjustable counterweight 37 mounted on a rod 38 fixed to arm 23.
  • a length of tape such as 10 is fed to the applicator from any suitable source of supply in such manner that a section thereof is in contact with a major portion of the peripheral surface 26 of the roller.
  • the tape is fed over free-running rollers 39 and 40 mounted on brackets 41 and 42 carried by the frame 14 whereby it is fed onto an upwardly travelling portion of surface 26 and thence along the downwardly travelling portion of surface 26 until it comes into contact with the surface portion of sheet 35 upon which the roller rests.
  • the tape will be in contact with about three-quarters of the length of surface 26.
  • the tape l is fed onto roller surface 26 with the surface of layer l1 in contact therewith whereby the surface of layer 12 will be brought into contact with sheet 35.
  • Surface 26 is heated by the heating means described to a degree only suffi cient to render layer l2 adhesive and therefore without affecting the stability of layer ll. Ordinarily, the surface 26 will be heated to a temperature in the range of 200 F, to 400 F., for example, about 300 I".
  • the hot-melt adhesive layer l2 comes in contact with no surface ofthe applicator, there is no undesirable transfer of softened adhesive to parts thereof. In other words, heat transfer to the layer l2 is effected through the heat-stable layer ll. Moreover, the heat-stable layer ll imparts to the tape a tensile strength that is at least several times that of a tape composed solely of a hot-melt adhesive,
  • the diameter of roller 25 will be such that its circumference will have an extent chosen to provide a particular dwell time of the tape thereon, such dwell time being substantially only sufficient to render the layer 12 adhe sively bondable to the sheet 35.
  • An example of a satisfactory diameter is about 18 inches.
  • the tape of FIG. 3 may, of course, be applied by the applicator in the same manner as tape 10.
  • the dimensions of the tape will vary in accordance with its conditions of use. Obviously, its width may vary within wide limits. lts thickness will also be variable but an example of a satisfactory tape l0 for standard use is about 0.008 inch, layer ll having a thickness of 0.005 inch and layer 12 having a thickness of 0.003 inch.
  • a tape applicator comprising a supportingvframe, an arm pivotally mounted in said frame, a roller rotatably mounted on said arm and having a tape engageable peripheral surface, a heating element in said roller for heating said surface, means for directing a length of tape onto said surface, a sheet-supporting surface, said roller having its peripheral surface resting upon said surface, and counterweight means connected to said arm for adjusting the pressure of said roller on said sheet-supporting surface.
  • a tape applicator as defined in claim l including a guide rail, a guide fixed yto said frame and slidable along said rail, and means for adjusting the position of said frame and applicator on said rail.
  • a tape applicator as dened in claim 2 including tape guiding rollers mounted on said frame for guiding tape onto said peripheral surface.
