Abstract
A seamless belt is fabricated by application of a coating to an endless substrate. The substrate is elastically stretched over a hollow cylindrical elongated support mandrel. The mandrel is formed of a porous material. Fluid is applied under pressure through the mandrel to form a layer of fluid between the outer surface of the mandrel and the inner surface of the substrate. The flow of fluid is manipulated to axially displace and to rotate the substrate on the outer surface of the mandrel. The flow of fluid is manipulated to orient a selected portion of the surface of the substrate to an angle to a direction of application of a coating. The temperature of fluid is manipulated to assist in substrate temperature control at steps of the coating and drying process.
Claims21
A process for fabrication of a seamless belt by application of a coating to an endless substrate, comprising:
- (1) elastically stretching an endless substrate over a hollow cylindrical elongated support mandrel, said mandrel being formed of porous material;
- (2) applying fluid under pressure through said mandrel to form a layer of fluid between an outer surface of said mandrel and an inner surface of said substrate;
- (3) manipulating the flow of said fluid to axially displace and to rotate said substrate on the outer surface of said mandrel;
- and
- (4) manipulating the flow of said fluid to orient a selected portion, less than an entire surface of said substrate, to alter an angle of said portion in relationship to the surface of said mandrel to an angle according to a direction of application of a coating to achieve a coating angle necessary for producing optimal coating results.
