Abstract

1,262,701. Coating paper; doctor blades. ETHYL CORP. 3 Feb., 1969 [8 Feb., 1968], No. 5703/69. Heading D1L. A paper web 4 is coated on both sides, e.g. from a roller coater, and the coating is then simultaneously doctored on both sides by a pair of opposed flexible blades 10, each of which has a flat bevelled working surface and is inclined at an acute angle to the direction of web movement, the blades being urged together with a force sufficient to establish at least a partially flush engagement of the working surfaces with the web. In Fig. 2 the blade holders 11 are angularly adjustable and each whole blade assembly slides on rails 24 via a carriage 12. A pneumatic cylinder 13 (only one shown) urges each carriage against the adjustable stop 24 at a pressure e.g. of 8-30 psig. Blades made of polyurethane, nylon, PTFE or polyethylene are mentioned, having a thickness of “-¢inch a P and J plastometer value of 4-27 and shore A hardness of 70-95. The angle of bevel may be 30-50‹ and the leading edge of the working surface of the blade be cut back at 90-95‹. The acute angle to the web may be 40-60‹ being, advantageously, greater than the bevel angle.
