Problems solved by technology

[0018] In other words, this known method may be difficult to implement depending on the type of board to be produced; thus, for example, it has not been shown that polyurethane resin boards and phenolic resin boards can be produced efficiently by the same method
[0019] It may also be difficult to implement if, in order to increase plate throughput, the advancing speed of the metal strips to which the resin is applied is increased, or if the amount of applied resin is increased because of the need to manufacture thicker plates

Embodiment Construction

[0032] The first of these figures shows a plant, generally designated 1, for the continuous manufacture of panels according to the invention, starting from two reels 2, 3 of metal strips 4 and 5.

[0033] In this plant 1 the slats, after being unrolled, are processed by respective forming machines 6 and 7 in which usual edges, ribs, profiles etc. are formed in a known manner.

[0034] Downstream of the forming machine, the strips 4 and 5 are brought together until the area where the expandable resin is applied; this operation is carried out in two steps.

[0035] Specifically, the first step consists of spraying the quick-response resin by the head 9; image 3 indicated by the middle arrow) and is provided with a nozzle of a type known per se and not shown in the figure. The speed of advancement of the lower slat 4 is set in such a way that the resin sprayed on it forms a layer 13 uniformly covering the slat 4 before it expands (at least partially) to a position below the sec...

Abstract

There is disclosed an insulating panel (20) and a method for continuous manufacturing thereof, wherein a polyurethane expansible resin (13) of the quick-reaction type is sprayed on a strip (4); after the sprayed resin has expanded, another resin (17) is poured in liquid condition, thereby obtaining the insulating core of the panels. The invention also concerns the apparatus for carrying out the method.

Description

technical field [0001] The present invention generally relates to the production of composite insulating panels. Background technique [0002] It is known that these panels, also commonly called "sandwich" panels, are widely used in the construction of walls, roofs, coverings, slabs, composite doors, etc. in civil and industrial construction; room or refrigerated container. [0003] The panels considered here basically consist of two opposing faces, between which is an insulating core made of expandable resin, also commonly called foam; this core is usually polyurethane foam, but can also be phenolic Foam or other forms of foam. [0004] The industrial production of these plates can be carried out in a continuous or discontinuous manner. [0005] The first case is particularly useful for the mass production of panels with a metallic outer surface; for this purpose, two metal strips are advanced one above the other along an in-line production plant, unrolled from their res...
