    摘要: Apparatus for the continuous manufacture of laminated foam articles, comprising a foam dispensing means for applying foam-foaming ingredients to sheet material which is to form one of the facings of the laminate and a conveying means for causing that sheet together with another sheet which is to form the other facing to move parallel to each other while the foam core is formed between them, the conveying means consisting of upper and lower parts one or both of which can move up or down with respect to the other part and exerting a predetermined constant pressure on the components of the laminate. The conveying means is characterized in that each of its movable parts comprises an endless series of slats mounted parallel to one another and transversely to their direction of motion and each independently carried on one or more endless chains by means whereby each slat is yieldingly urged outwardly from the chain or chains into contact with a sheet of facing material. The apparatus is of particular value for the production of laminated articles in which at least one of the facing sheets is pre-formed with lateral flanges, ridges or other convex configurations.
