Appeal No. 2002-1200 Page 4
Application No. 09/351,164
Independent process claim 1 calls for a step of detachably bonding the
packaging web to the circumference of the material web roll with the aid of pressure-
sensitive adhesive and independent device claim 8 calls for a pressure-sensitive
adhesive dispenser, which we interpret as requiring a dispenser supplied with pressure-
sensitive adhesive material. The examiner concedes that Schölzke, the jumping off
point of the obviousness determination, does not disclose the use of pressure-sensitive
adhesive, but contends that Zweber would have suggested such in Schölzke’s
apparatus and method “to permit the clean detaching of the wrapper from the roll”
(answer, page 4).
Schölzke discloses an apparatus for wrapping a material roll 2 with a packaging
web 3 comprising a web dispenser 8, calender roll 5 which turns the roll 2 and a second
calender roll 4. The web dispenser includes a first or operating adhesive substance
application device 15 and a second or final adhesive substance application device 16.
The final adhesive substance application device 16 sprays a quick acting [curing]
adhesive on the beginning of the packaging web 3 to adhere the upstream end portion
of the web to the roll. The application of the quick acting adhesive ends after a short
distance and only the operating adhesive substance, which is slower acting but more
economical, is sprayed onto the successive portions of the web by the operating
adhesive substance application device 15. Quick acting adhesive from the final
adhesive substance application device 16 may also be applied for a short distance at
