THE INVENTION
Appellants’ claimed invention is directed toward a method
for laminating a sheeted topfilm to a sheeted substrate while
holding the topfilm in tension and maintaining registration
between the topfilm and the substrate (specification, page 1,
lines 7-10). Claim 1 is illustrative and reads as follows:
1. A method of laminating a sheeted topfilm to a sheeted
substrate comprising the steps of:
a) registering the sheeted topfilm with the sheeted
substrate;
b) removing the sheeted topfilm from the sheeted
substrate, the sheeted topfilm being carried by a first
platen;
c) activating a means for laminating the topfilm and the
sheeted substrate to each other;
d) bringing a portion of the sheeted topfilm into contact
with a portion of the sheeted substrate, the portions in
contact defining a contact patch; and
e) moving the first platen relative to the sheeted
substrate to advance the contact patch in a propagating
direction across the sheeted substrate and laminate the
topfilm to the sheeted substrate while simultaneously
tensioning the sheeted topfilm in the propagating direction.
