Patent ID: 8414284

Claim:
An apparatus for forming an elastomeric strip, the apparatus comprising: a roller having a cylindrical surface, the roller rotating at a predetermined angular velocity; a stationary, contoured arcuate guide-surface which tapers toward the roller and confronts the roller coextensively, the arcuate guide surface forming part of a vertically adjustable die-blade, the die-blade being vertically adjustable by pivoting of the die-blade about a horizontal axis to permit adjustment of the clearance between an upper surface of the roller and the arcuate guide surface; an adjustable surface confronting the upper surface of the cylindrical surface and having a first stationary position relative to the upper surface of the cylindrical surface such that the apparatus forms an elastomeric strip having a first thickness, the adjustable surface being adjustably pivotable relative to the upper surface of the cylindrical surface such that the adjustable surface moves to a second stationary position for forming an elastomeric strip having a second thickness, the adjustable surface having a hemispherical surface opposing the roller; angled spacers inserted behind the adjustable surface for simultaneously rotating the guide surface in relation to the elastomeric strip and keeping the guide surface in contact with the roller; and a pair of stationary, low-friction, bearing members for directly engaging the roller and permitting generally unrestrained rotation of the roller.
