An apparatus forms an elastomeric strip. The apparatus includes a roller and an adjustable surface. The roller has a cylindrical surface. The roller rotates at a predetermined angular velocity. The adjustable surface confronts the cylindrical surface and has a first stationary position relative to the cylindrical surface such that the apparatus forms an elastomeric strip having a first thickness. The adjustable surface is adjustably pivotable relative to the cylindrical surface such that the adjustable surface moves to a second stationary position for forming an elastomeric strip having a second thickness.
