specification as originally filed. From our review of the
specification, we additionally find that:
(1) “the roller is a generally integral single piece
component formed of suitable polymer.” (page 3).
(2) “[w]here conventional rollers are assembled from
numerous parts, usually metal, to produce a hollow roller, the
conveyer roller of the present invention departs by being
constructed as a monolithic unit from a polymer material.) (page
3).
(3) “[i]t is an advantage of the invention to provide a
monolithic roller.” (page 4).
(4) “[m]anufacturing may be made simple by machining an
elongate piece of round stock to a suitable diameter, boring the
stock, cutting to length and detailing the ends to suit.
Surprisingly, it is efficient to machine rollers 10 from readily
available round stock.” (page 6).
The specification discloses that the roller is formed from
an integral, single piece component formed of polymer, and that
the monolithic construction may be made by machining a piece of
round stock, boring the stock, cutting to length and detailing
the ends. We find from the specification that monolithic refers
to being formed from a single piece of material. This is
