Appeal No. 2005-0777
Application No. 10/081,881
The claimed invention solves the problem of maintaining a good
grip on the roll of laminate film under tension by providing a
groove in the shaft, with a deformable flexible tube in the
groove, so that the deformable flexible tube will touch the
inside of the core of the roll of film to cause tight engagement
between the roll and the shaft (Brief, pages 2-3).
Representative independent claim 1 and dependent claim 7 are
reproduced below:
1. A lamination apparatus to form lamination layers of
laminate film pasted on surfaces of printed matter,
containing a shaft to support a core roll with films wound
therearound, wherein said shaft has a cylindrical surface
and an axial direction, said shaft having a groove on the
cylindrical surface along the axial direction where a
deformable tube and having two ends is set with both ends
fixed by fittings.
7. The lamination apparatus according to claim 1,
wherein said deformable tube comprises a soft vinyl.
In addition to the admitted prior art as shown in Figures
5 through 7, as described on pages 1-4 of the specification, the
examiner has relied upon the following references as evidence of
obviousness:
Hahn 3,606,187 Sep. 20, 1971
Kataoka 4,496,114 Jan. 29, 1985
