Abstract
A microwave binder is used in conjunction with paper tape which is coated with one or more formulations of encapsulated, fast setting, water soluble adhesives to bind pages of a book. The tape spine adhesive is of sufficient thickness to allow it to penetrate into the edges of the pages of the bound edge. The microwave heating causes the capsules to rupture, releasing the adhesives to flow into the bound edge of the book.
Claims2
A microwave energy activated binding tape for use in binding pages together to form a book, comprising in combination:
- a) a backing strip, said backing strip being composed of paper;
- b) a microwave energy activatable first stripe of water soluble adhesive on said tape, said microwave energy activatable first stripe extending longitudinally of said backing strip substantially along the center thereof, said microwave energy activatable first stripe having a width less than the width of said backing strip whereby two side portions of said backing strip extend along each side of said microwave energy activatable first stripe;
- and
- c) a microwave energy activatable second stripe of said water soluble adhesive and a microwave energy activatable third stripe of said water soluble adhesive on each of said two side portions of said backing strip,
- wherein said water soluble adhesive includes aluminized particles therein.
A microwave energy activated binding tape for use in binding pages together to form a book, comprising:
- a) a backing strip, said backing strip being composed of paper;
- b) a microwave energy activatable first stripe of hot-melt glue on said tape, said microwave energy activatable first stripe extending longitudinally of said backing strip substantially along the center thereof, said microwave energy activatable first stripe having a width less than the width of said backing strip whereby two side portions of said backing strip extend along each side of said microwave energy activatable first stripe;
- and
- c) a microwave energy activatable second stripe of said hot-melt glue on one of said side portions of said backing strip;
- d) a microwave energy activatable third stripe of said hot-melt glue on the other of said side portions of said backing strip;
- wherein said microwave energy activatable first, second and third stripes of hot-melt glue include aluminum particles dispersed therein for increased heat conduction.
