Abstract
Apparatus and method for forming deckle-free edges and windows in molded fiber products such as cartons, trays and the like, said apparatus comprising a forming mold equipped with non-porous block-out ridge and/or patch members to define the periphery and/or windows in the finished product. The apparatus includes a mating press mold for cooperation with the forming mold with passageways therein through which jets of fluid such as air and/or steam may be supplied from a high pressure source to control deckle accumulated on the forming mold. The method of forming deckle-free windows and/or edges in molded fiber products by applying a fiber pulp slurry on the face of a forming mold and removing deckle from block-out portions of said forming mold by directing high pressure jets of fluid at said mold to blast deckle into upstanding position and away from adjacent portions of said mold and pressing the upstanding deckle down into pulp there-below thereby concentrating fiber in the vicinity of edges and windows in the finished product.
