摘要
Apparatus and method for forming deckle-free windows or openings in molded fiber products such as cartons, trays and the like, said apparatus comprising an air distributor manifold box with jet tube means whereby a blast of air may be directed against a block-out patch to lift deckle therefrom. The manifold box being movable to a discharge position and in contact with switch means which is operable to open a solenoid valve in fluid conduit means which connects said manifold box to an air accumulator tank. The operation of said apparatus providing the said method of removing deckle from the surface of block-out patches disposed on forming molds to form windows. The method of removing deckle from the surface of block-out patches by an air jet and pressing the up-lifted deckle into surrounding fiber portions to reinforce said surrounding portions.
