Abstract
1432802 Making sheet material ARMSTRONG CORK CO 12 April 1973 [12 April 1972] 17598/73 Heading B5A A method of making thermoplastics sheet material, e.g. for vinyl floor tiles, comprises the steps of consolidating material into a sheet by rolls 1, 2, feeding the sheet to an inclined fluidcovered slide 5 where it is cooled, retarding the movement of the sheet by rolls 9, 10 so that a hump 11 is formed and the sheet is subjected to compressive stresses. The slide can be covered by air or water, and is pivotally mounted at 7. The sheet vinyl can be filled with asbestos or limestone. The rolls 9 and 10 can be replaced by a slow moving conveyer. The method can be used with asphalt, coumarone-idene resins, polystyrene, and polyurethane.
