Application No. 09/294,354
OPINION
In reaching our decision in this appeal, we have given careful consideration to
the appellant's specification and claims, to the applied prior art references, and to the
respective positions articulated by the appellant and the examiner. As a consequence
of our review, we make the determinations which follow.
The appellant’s invention is directed to improvements in roll winding machinery in
which first and second column devices that support the rolls are connected to each
other in the lateral direction by a cross bar, and the cross bar comprises the sealing box
that is disposed underneath the winding bed, which is furnished with pressurized air to
generate an air cushion under the rolls. According to the appellant, the use of the
sealing box as a strengthening cross bar simplifies the structure while providing
sufficiently high mechanical stability to absorb the stresses generated during the
operation of the winding machine. The invention is recited in claim 1 in the following
manner:
1. A roll winding device, comprising a winding bed and at
least one support device comprising at least one carrying roll
having a first end and a second end and a longitudinal axis
disposed in a lateral direction with respect to a direction of
travel of a web, in a machine frame comprising a column
device at each of the two ends of the carrying roll, said
column devices being connected to each other in the lateral
direction by at least one cross bar, at least one cross bar
comprising a sealing box that is disposed underneath the
winding bed.
Claims 1, 2, 7-12, 18-22, 28-33 and 39-42 stand rejected under 35 U.S.C.
