Appeal No. 1997-0230
Application No. 08/416,668
adhesive to a porous carpet underlayment pad by applying a
liquid pressure sensitive adhesive to a release layer, drying
the pressure sensitive adhesive to form a dried pressure
sensitive adhesive film, and contacting this film with a carpet
underlayment pad. Claims 1 and 8 are illustrative and read as
follows:
1. A method for applying a pressure sensitive
adhesive to a porous carpet underlayment pad comprising
the steps of:
(a) applying a layer of a liquid pressure sensitive
adhesive polymer composition to the release
side of a release substrate;
(b) drying the pressure sensitive adhesive
polymer- containing layer to form a dried
pressure sensitive adhesive film on the
release substrate; and
(c) contacting the dried pressure sensitive
adhesive film to a surface of the carpet
underlayment pad so that the release substrate
forms an outer surface to the pressure sensitive
adhesive film.
8. A method for applying a pressure sensitive
adhesive to a porous carpet underlayment pad comprising:
(a) applying a layer of a pressure sensitive adhesive
polymer aqueous emulsion or a pressure sensitive
adhesive polymer organic solution to the
release side of a first release substrate;
(b) drying the polymer-containing layer to form a
dried pressure sensitive adhesive film on the first
release substrate;
(c) applying a second release substrate to the dried
adhesive film, so that the release side of
the second release substrate is in contact
with the adhesive, to form an encased
