METHOD OF, AND APPARATUS FOR, COATING A CYLINDER

摘要

Disclosed is coating apparatus comprising a front roller (18) and rear roller (20) and means to rotate them in the same rotational sense and contrary to the direction of rotation of a parallel cylinder (12) to be coated with a fluid material, which hardens to a resilient coating, by creating above the nip (25) between the front and rear rollers a reservoir (26) of the fluid material whereby the front roller carries on its surface a layer of the fluid material round to the nip (29) between it and the cylinder to be coated, thereby continuously to build up the thickness of the coating (32) on the cylinder. Heating elements and temperature sensors in a hood (14) around the cylinder maintain an optimum coating temperature.
