labels vertically in a stack (page 2). The label stacking
device 10 includes a label-input conveyer 14 including rollers
22 mounted on shafts 20 (Figures 2 and 4) and driven by
electric motor 31 via gear train 30 (page 5) and rollers 42
mounted on shafts 41, which are not driven (page 6). Rollers
42 are preferably flexible in order to guarantee that driven
rollers 22 are correctly pressed (id.). Mistyurik also
teaches that the flexibility of rollers 42 improves the
advancement of labels of different thicknesses (id.).
The examiner describes (answer, page 3) Tekavec as
showing
a stock supply assembly (50), a conversion assembly and
upper and lower drive rollers (54), arranged as a
conveyor, for transferring cut products through an
arcuate path leading from a machine exit to a passage in
the work table. Thus, Tekavec teaches the invention
substantially as claimed except for duplicating the
Tekavec upper and lower drive rollers such that the upper
and lower drive rollers are arranged in series along the
Tekavec arcuate path.
The examiner also describes (answer, pages 3-4) Mistyurik
as teaching that
utilizing complementary upper and lower series of drive
rollers about an arcuate path extending from a first
lower position to a second upper position improves the
reliability of a work piece conveying device by ensuring
that work pieces are transferred by friction along the
