Definitions

  • Pressure-sensitive adhesive tapes are ordinarily sold in roll form, wound upon a cylindrical core.
  • Such telescoping occurs when the radial compression or squeezing causes a lateral displacement of the turns of the roll toward one side, the amount of displacement increasing outwardly from the core so that a funnel-shaped roll of tape is produced.
  • the adhesive exposed through telescoping is easily contaminated, thereby impairing the properties of the tape.
  • the present invention provides tape Wound on cores employing a new technique for relieving radial compression forces in the roll.
  • the cores used in the present invention are particularly suitable where substantial amounts of shrinkage are desirable, as where stretchy plastic-backed tapes are wound thereon under tension.
  • the present invention employs a segmented core which is held in an expanded position during the winding of the tapes. The segments in the expanded position are spaced apart, forming a core which has slight gaps or spaces therein between the segments.
  • uniform radial re lief is provided across the width of the core from the compressive forces caused by winding tension, variable thickness, volumetric changes in the physical size of the tape due to temperature and humidity changes, or other shrinkage forces.
  • the core segments are forced together to form a continuous core of predetermined size.
  • the compression of the core can be accomplished simply by removing the core with the tape wound thereon from the mandrel.
  • the segments are held together as a stable core by means of the inward forces from the tape roll on the arch-like segments and, generally also by frictional forces between the core and the inner wrap of the tape.
  • the cores of this invention allow a larger amount of radial contraction than previously obtainable, the amount of collapse being predetermined in each case by the length of the segments and spaces therebetween which are provided in the design of the core. Tapes Wound on such cores have resulted in unexpectedly neat, uniform, and stable rolls.
  • the individual segments of the core can be secured together by hinged elements or an elastic sleeve.
  • Cores in which the segments are thus secured together are as equally expandable and collapsible as those in which the segments are completely separated and are more easily handled.
  • FIGURE 1 is a perspective view illustrating assembled expanded core segments prior to winding thereon of the tape and slitting
  • FIGURE 2 is a perspective view of a roll of tape of this invention illustrating a core in retracted position
  • FIGURE 3 is a perspective view of a roll of tape illustrating a further embodiment of the invention wherein the core is provided with dovetailed or interlocking segments;
  • FIGURE 4 is a side view of a core illustrating a still further embodiment of the invention wherein the core segments are hingedly interconnected;
  • FIGURE 5 is a perspective view of one form of manddrel which can be used for holding the cores of the invention in the expanded position during winding, and
  • FIGURE 6 is a cross sectional view along line 66 in FIGURE 5, and also shows the mandrel in expanded position with dotted lines.
  • the core segments 10, 12, and 14 are expanded as shown in FIGURE 1 during the normal winding and/or slitting operations so that a gap exists between the segments during winding and/or slitting.
  • An expandable and collapsible mandrel, described below, is used to hold the core segments in the expanded position.
  • tape 16 is wound under tension around the core segments.
  • the core with the tape thereon is then slit, using conventional slitting equipment to form the desired roll of tape 18 of the desired width, as shown in FIGURES 2 and 3.
  • the tape and the cores may be slit prior to winding, if desired.
  • core segments 20, 22, and 24 may optionally be provided with dovetailing or otherwise mating ends. Such interlocking may be desired in cases where the roll is under very low tension after contraction of the core, in order to eliminate the possibility of any endwise slippage of the core segments relative to each other.
  • the segments of the cores can be joined together by elastic or hinged elements which hold the segments together for ease of handling of the cores and to provide increased stability to the rolls.
  • the segments can be affixed to an elastic sleeve which is positioned either around or inside the segments. Such a sleeve expands and contracts with the core, and eliminates the need for handling individual core segments. If such a sleeve is positioned around the segments, a uniform surface is provided, on which the first wrap of tape can be wound.
  • FIGURE 4 Another means of joining the core segments together is shown in FIGURE 4.
  • segments 26, 27, 28, and 29 are assembled together by hinge elements 30, 31, 32 and 33.
  • the latter hinge elements retain the segments in the desired positions with relation to each other, and thus provide easy assembly of the segments over a mandrel, while at the same time allowing the de sired amount of expansion and contraction of the core.
  • the construction of FIGURE 4 admits itself readily to the formation of the hinged, segmented cores by extrusion of a plastic material in continuous lengths. The extruded tubes can then be cut to any desired shorter length.
  • mandrels can be used to hold the cores in expanded position during winding.
  • the mandrel may be expanded mechanically or by means of hydraulic or gaseous pressure.
  • the core-supporting surface of the mandrel may, for example, consist of curved metal segments or an elastic sleeve.
  • the mandrel shown in FIGURES 5 and 6 for purposes of illustration employs a number of mechanically expand-able sections 34, 35, 36, 37 (not shown), 38, and 39 (not shown) whcih are preferably arcuate segments of equal length.
  • Each of the sections has a number of metal protrusions, e.g., 42 and 44, affixed to it.
  • Each protrusion preferably has an inclined surface 43, 45.
  • the arcuate segments are assembled around a shaft 46.
  • Each protrusion fits into a mating depression, e.g. 47 and 48, in shaft 46.
  • Shaft 46 has a drive gear 60 aflixed to one end to provide a means for rotating the mandrel during the tape winding operation.
  • the number of segments used in making a particular core is a matter of choice, as it is possible to form suitable cores having various numbers of segments.
  • segments of equal length on any given core but it will be understood that segments of different lengths may be used.
  • the circumference of the cylinder or other annulus for making the core segments should be chosen with due regard for the final diameter desired in the final core.
  • the size of the gaps or spaces used between the segments is then selected experimentally to best allow for the shrinkage required for the particular tape to be wound on the core under a given winding tension.
  • the cores used in the practice of this invention can be formed from any stiff, relatively rigid, compression-resistant material such as cardboard, plastic, or the like.
  • the cores of this invention can be used for winding stretchy films or tapes of any composition, for example, polyvinyl chloride, polyolefin and polyester polymers, silicone rubbers, and other stretchy plastic, rubbery, or elastic materials.
  • the tapes may be uncoated or coated with an adhesive, for example a pressure-sensitive adhesive.
  • adhesives are known to those skilled in the art, and may be, for example, of the rubber-resin, acrylate, or polyvinyl ether type.
  • Examples of adhesive tapes which may be used with the cores of the present invention are those shown in US. Patent Nos. Re. 23,843 (Oace et al.) issued June 29, 1954; 2,882,183 (Bond et al.) issued Apr.
  • the cores of this invention perform particularly well with very stretchy tapes because substantially more radial displacement is possible with the cores of the present invention when compared to prior known devices.
  • a roll of pressure-sensitive adhesive tape of the type having a normally tacky adhesive coating upon a flexible backing wound upon an annular core formed from a stiff relatively rigid material, said core being formed from at least two separate arcuate segments which together form said annulus, said segments being held in position by radially compressive forces of said tape thereon.
  • a method of forming stable rolls of polymeric film material wrapped around a core which comprises (1) providing an annular core,
