PRODUCTION OF RUBBER-COATED ROLLER

PURPOSE:To eliminate the loss of materials and to uniformize film thicknesses by retreating a 1st blade from the roller, disposing a 2nd blade so as to maintain a prescribed spacing from the roller, revolving the roller and cutting the coating film at both ends thereof.

Summary:PURPOSE:To eliminate the loss of materials and to uniformize film thicknesses by retreating a 1st blade from the roller, disposing a 2nd blade so as to maintain a prescribed spacing from the roller, revolving the roller and cutting the coating film at both ends thereof. CONSTITUTION:A rubber material 40 is supplied to the spacing between the horizontally held roller 10 and the 1st blade 20 and the roller 10 is rotated, by which the rubber film of the film thickness determined by the size of the spacing is formed on the outer periphery of the roller. The thick parts at both ends of the roller formed when the rubber film is shifted by centrifugal force or surface tension during the idling of the roller 10 executed in order to erase the traces of formation of the blade 20 further after the application are cut so as to be thinner than the thickness of the desired rubber coating film by disposing the 2nd blade 22 into the spacing narrower than the spacing between the 1st blade 20 and the roller 10 and revolving the roller. The roller is further idled to remove the traces of the 2nd blade; in addition, the rubber material is shifted to both ends by the centrifugal force, etc., by which the thin film thicknesses at both ends are offset. The desired film thickness is obtd. in this way and the film thickness over the entire part of the roller is uniformized.
