Abstract
A method of manufacturing a cylindrical compressible laminate using the floating knife or knife over roll spreading techniques to apply an inner compressible layer and outer or surface layer of a substantially incompressible material. The coating system includes a coating head to dispense an elastomeric material onto a rotating laminate and a knife blade that is parallel to the axis of rotation to distribute and spread a uniform coating of the elastomeric material. The knife blade can be raised incrementally on each rotation of the laminate so that an additional coating can be applied, until a layer of a desired thickness is obtained. In the preferred embodiment, the coatings are at least partially cured during each rotation.
