    摘要： An apparatus for continuously forming a continuous element made of expanded plastic material comprises: a loading section of a mass of granules made of expandable plastic material; a sintering section of the continuous element made of expanded plastic material extending downstream of the loading section; a stabilizing section of the continuous element made of expanded plastic material extending downstream of the sintering section; a forming tunnel extending along the sintering and stabilizing sections and defined between a pair of lateral walls and a pair of gas permeable conveyor belts, supported by respective supporting tracks. Further, at least one of the supporting tracks of the gas permeable conveyor belts comprises at least one portion extending in the sintering section and angularly tiltable with respect to a transversal centerline plane (π) of the forming tunnel for varying the height of the tunnel in a longitudinal direction.

    摘要： APPARATUS FOR PRODUCING HOT AND COLD INSULATING SHEET CONSISTING, AT LEAST IN PART, OF FOAMED PLASTIC. AT LEAST ONE BASIC CONSTITUENTS OF A PLASTIC ARE MIXED WITH AT LEAST ONE ACTIVATING AGENT AND DIRECTED INTO A GAP FORMED BY AT LEAST TWO SPACED APART SURFACES. THE MIXTURE FORMS A SHEET OF FOAMED PLASTIC, THE THICKNESS OF WHICH IS DETERMINED BY THE SIZE OF THE GAP. THE GAP SURFACES MAY BE FORMED OF SHEETS OF FLEXIBLE FOIL MOVED OVER GUIDES OR ROLLERS AND MAY BE MADE OF MATERIAL TO WHICH THE FOAMED PLASTIC WILL ADHERE. THE RESULTING INSULATING SHEET MAY THUS HAVE ONE OR MORE LAYERS OF THIS FOIL AS A PROTECTIVE COATING OVER THE FOAMED PLASTIC. THE INSULATING SHEET PRODUCED ACCORDING TO THE PRESENT INVENTION CAN BE MADE THIN AND FLEXIBLE IF DESIRED, AND MAY BE USED IN THE MANUFACTURE OF PRODUCTS, SUCH AS CONTAINERS OF ALL KINDS, WHICH FIND NEED FOR ITS HOT AND COLD INSULATING AS WELL AS SHOCK ENERGY ABSORBING QUALITIES.

    摘要： A process for manufacturing an insulation board comprising a rigid polyisocyanurate foam core having two major surfaces and a facing material on at least one of the major surfaces, comprising (a) conveying a facing material along a production line for attachment to one major surface of the core; (b) applying a foam-forming mixture of polyisocyanurate to the facing material such that the mixture is applied along the entire width of the facing material; (c) optionally conveying a second facing material along the production line for attachment to the other major surface of the core; (d) conveying the facing material with applied foam-forming mixture into a laminator which comprises a gap for foam expansion and allowing the mixture to foam and expand to fill the gap within the laminator; and (e) curing the foam. The process provides excellent boardstock thickness control, minimal wasted densification at the foam/facer interface, greater compressive strength and high line speed.

    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.
