FIG, 2

Referring to Fig, 1, an elongated member includes a sub-
strate 1 having a layer of pressure sensitive adhesive 4,
a protective sheet 5 over the adhesive 4, a layer of high
tack adhesive 2 and a centrally disposed layer of low tack
adhesive. A typical high tack adhesive may be a mixture
of polyethylene, a rosin acid, and a metal salt of a car-
boxylic acid, present in weight proportions of 80/10/10.

A typical low tack adhesive may be a mixture of about 80%
by weight of an ethylene/vinyl acetate copolymer having a
40% ratio of ethylene to vinyl acetate and about 20% by
weight of rosin acid ester, The member may be bound to a
stack of sheets 6 by book binding apparatus such as is
disclosed in U. S. patent 3,928,119, Referring to Fig. 2,
after binding occurs, sheet 5 may be removed and the adhe-
sive 4 may be brought into contact with a cover 7, thereby
providing a covered book.
