Appeal No. 1997-3243
Application 08/290,093
nonelected invention.
THE INVENTION
Appellant’s claimed invention is directed toward a
product for forming mailers, which includes a paper web which
has a pressure sensitive adhesive applied to at least one of
its faces in a pattern for forming mailers. The web is wound
into a roll to form multiple plies under a specified tension
such that the magnitude of the tension and the weight of the
roll are insufficient for the adhesive on one roll ply to
adhere to an adjacent roll ply. Claim 10 is illustrative and
reads as follows:
10. A roll pressure seal product for forming mailers
comprising:
a roll formed of a paper web wound to form multiple
plies;
a pressure-sensitive adhesive applied to portions of at
least one face of said paper web and arranged in a
predetermined pattern for forming multi-ply mailers, said roll
being wound under a predetermined web tension between about
1.5 to 3.0 lbs/lineal inch and having a weight sufficient to
avoid adhesion of the pressure-sensitive adhesive between
adjacent roll plies at said face portions.
