Abstract
A coating apparatus is provided with a front roller and a rear roller which rotate in the same rotational sense and opposite to direction of rotation of a parallel cylinder to be coated with fluid material which hardens to a resilient coating thereon. A reservoir of fluid material is provided above a nip between the front and rear rollers, so that the front roller carries a layer of fluid material on a surface thereof to a nip formed between the front roller and the cylinder to be coated, thereby continuously building up thickness of the coating upon the cylinder. Heating elements and temperature sensors in a hood around the cylinder maintain an optimum coating temperature.
