Abstract

1496963 Apparatus for coating webs AGFA - GEVAERT AG 14 May 1975 [15 May 1974] 20314/75 Heading D1L A machine for coating a web with solutions or dispersions comprises a coating roller 1 over which a web 2 to be coated is passed and a coating block 3 which defines with the roller a coating gap 4 where the web is coated. The coating solution is delivered to the gap 4 from below through a rectangular duct 6 which is not open right up to the coating edge but is closed by a rectangular board 7 which is displaceable transversely to the web to adjust the width of coating. The final layer thickness is determined by air brush 5. The lateral faces of the rectangular board 7 are preferably coated with a graphiterubber layer in order to obtain satisfactory sliding and seating in the duct. Rectangular boards can be arranged if required on both sides of the machine.
