Abstract
PURPOSE:To mold a bubble-free molded sheet by preventing expansion of air mixed into an unvulcanized sheet, by providing such a specific cooling and pressing device as to bring the unvulcanized sheet into contact with a top and bottom forces only at the time of pressing and vulcanization molding. CONSTITUTION:Pressing plates 26, 27 provided with an air cooling path is provided on the fringe of an introduction side of an unvulcanized sheet 1 of a top and bottom forces 22, 23 of a vulcanization molding machine 13. The title device is constituted so that the unvulcanized sheet 1 is held by the cooling and pressing plates 26, 27 and the unvulcanized sheet 1 does not come into contact with the top and bottom forces 22, 23 except at the time of pressing and vulcanization molding. As the unvulcanized sheet 1 does not come into contact with both the heated forces 22, 23 except at the time of the pressing and vulcanization molding, expansion of air contained into the unvulcanized sheet 1 is prevented. Therefore, a molded sheet free from bubbles is obtained.
