Claims
- 1. A strip of binding tape comprising
- a strip of porous non-woven fibrous backing of polymeric material,
- a coating of an acrylic pressure-sensitive adhesive on one surface of the backing, and
- means defining a tab on at least one end of a said strip covering at least a portion of said adhesive, said tab being separable from said strip and having an opening therein for alignment of a said strip.
- 2. A strip of binding tape according to claim 1 wherein a low-adhesion backsize is placed on said backing of polymeric material to permit winding and stacking of a plurality of said strips.
- 3. A strip of binding tape according to claim 2 wherein the sides of said strip have a tack eliminator coated thereon.
- 4. A pad of pressure-sensitive adhesive tape strips positioned in a stack for use in binding sheets together, said strips comprising
- a backing of a nonwoven fibrous material covered on one surface with an acrylic copolymer pressure-sensitive adhesive, barrier coat means on the opposite surface of said backing for restricting adhesive migration through the backing, and a low-adhesion backsize on said barrier coat means,
- each strip having attached to each end thereof against a portion of the adhesive a strip of tab material to form a tab, at least one of said tabs being formed with an opening therein with the openings in the tabs being in aligned position.
- 5. A pad according to claim 4 wherein the sides of the stack of strips are treated with a tack eliminator.
- 6. A pad according to claim 5 wherein the tack eliminator affords a crosslinking of the adhesive exposed on the edge of the tape strips to restrict adhesive migration from the edges of the pad.
- 7. A pad according to claim 5 wherein the tack eliminator is tetra n-butyl titanate.
- 8. A strip of binding tape conprising
- a porous nonwoven fibrous backing of polymeric material,
- a coating of an acrylic pressure sensitive adhesive on one surface of the backing,
- a barrier layer on the opposite surface of the backing to cover the surface of the backing and interstices between the fibers to restrict adhesive migration through said backing, and wherein a tab is adhered one to each end of a said strip with the adhesive at the ends of said strip contacting a surface of the tab.
- 9. A strip of binding tape according to claim 8 wherein said barrier layer is a polymer to seal the backing and make it nonporous and nontacky.
- 10. A strip of binding tape according to claim 8 wherein said tab is coated on the surface contacting said adhesive with a low-adhesion backsize.
- 11. A strip of binding tape according to claim 8 wherein said strip of tape is perforated transversely adjacent the edges of the tabs contacting the adhesive.
- 12. A strip of binding tape according to claim 8 wherein at least one of said tabs has an opening formed therein to receive a locating pin.
- 13. A strip of binding tape according to claim 6 wherein said strip of tape is perforated transversely adjacent the edges of the tabs contacting the adhesive.
- 14. A strip of binding tape according to claim 1 wherein a low-adhesion backsize is placed on said barrier layer to permit winding and stacking of a plurality of said strips.
- 15. A strip of binding tape according to claim 8 wherein said backing comprises a nonwoven web of viscose rayon 11/2 denier fibers bound by a rubbery acrylate polymer.
