  • Adhesive fasteners are usually supplied in pairs, one attached at each side portion of the water-impervious backing sheet near one end of the diaper so that as the diaper is conformed to an infant, a free end of each fastener may be attached to the corresponding opposite end of the diaper to secure about the infant.
  • Various types of adhesive fasteners have been proposed in the past. In general, such adhesive fasteners are covered on their free adhesive ends by a release paper which is removed during the application of the diaper to the baby. The adhesive tape and the release paper are obtained during manufacture from separate rolls thereof.
  • One method and apparatus for providing adhesive fasteners from separate rolls of adhesive tape and release paper is disclosed in Wierzba et al., US. Pat. No. 3,728,191, issued Apr. 17, 1973.
  • Label stock a laminar assembly of a substrate and a release paper adhered to each other by an adhesive layer and wound together on a single roll, is more economical than conventional adhesive tape and release paper and this invention provides a suitable method and apparatus for utilizing label stock in the preparation of adhesive tabs for diapers.
  • the tape applicator of the present invention provides a novel method and apparatus for cutting and applying fasteners formed from label stock which is readily adaptable for mass-production of disposable diapers.
  • Label stock is produced in rolls and consists ofa substrate which may be formed from various suitable materials. Label stock is made by coating a release paper with a tacky, pressure-sensitive adhesive layer and then covering the release paper with a substrate material. The latter material adheres to the pressure-sensitive material much more strongly than the release paper; and in any subsequent separation of the layers, the adhesive layer remains on the substrate.
  • the present invention is particularly adaptable for use with label stock having a substrate which possesses isotropic tensile strength so that re-orientation of the fasteners cut therefrom is eliminated.
  • Substrates having maximum tensile strength in the transverse direction may also be utilized.
  • One substrate which is substantially isotropic in tensile strength is formed by melt extruding polyethylene fibers in random orientation to form a continuous film having isotropic tensile strength.
  • the present invention is particularly adaptable for use on mass production lines for producing disposable diapers and may be positioned at any position along the production line wherein the impervious backing sheet is moving.
