the other end portion of the web. Thus, in accordance with Schölzke’s invention, the
quick adhesion required for successful holding of the web to the roll at the beginning of
winding is accomplished in a relatively efficient and economical manner, because the
more expensive adhesive is used only on the ends and not throughout the entire length
of the web. Schölzke makes no mention of using a pressure-sensitive adhesive and
expresses no concern about providing a detachable bond of the packaging web to the
roll.
Zweber discloses a paper coin wrapper treated with a pressure-sensitive
adhesive, preferably an isoctylacrylate homopolymer adhesive cast on a paper
substrate at a low coating weight, on peripheral edges 36, 38 and along an inner
surface 30 thereof in any configuration which will maintain the coins in the desired stack
or roll. An exemplary adhesive-paper substrate combination enumerated by Zweber is
that found in the 3M brand “POST-IT”® notes (column 4, lines 5-7). The adhesive along
outside edge 26 generally contacts the coin wrapper itself rather than contacting the
coins and serves to maintain the wrapper in the rolled position. The adhesive provides
sufficient adhesion that the coin wrapper will remain wrapped but can be easily
unwrapped when desired. The adhesive readily and cleanly releases from the coins as
the wrapper is removed.
