Abstract
A binding tape for binding the shingled edges of sheets has a supple tough and flexible nonwoven fibrous backing coated on one surface with a pressure-sensitive adhesive and with a barrier coat to seal the backing on the other surface. A low adhesion backsize is coated on the backing to permit winding or stacking strips of tape. Tabs adhered to the ends of the strips aid in locating the strips in relation to the shingled edges.
Claims15
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.
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.
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.
