Abstract

See full text

A pattern roll especially adapted to form, in an in-line manner, peripheral edges of an article having substantially constant geometry and the pattern roll's method of fabrication are described. A bounded surface region is defined on at least a portion of a pattern roll's cylindrical surface by means of a number of circumferential and longitudinal (relative to the pattern roll's central axis) segments. Beveled surfaces are formed on these rib segments with the angle formed by the beveled surface of the circumferential segment being less that the angle formed by the beveled surface of the longitudinal segment. Notwithstanding this angular difference as between the beveled surfaces of the circumferential and longitudinal rib segments, when the pattern roll is then rotated in opposition to a platen roll so as to define a nip therebetween, and a molten thermoplastic is extruded into the defined nip, a plastic product having a peripheral beveled edge of substantially constant geometry will be formed.
