Abstract

An apparatus (1) for continuous process foaming of a panel (2), of the type comprising an intermediate layer of expanded material (3) externally covered by covering and protective layers (4, 5), comprises an upper conveyor (6) belt supported by a respective upper support and guide frame (8) and a lower conveyor (7) belt supported by a respective lower support and guide frame (9), frame-support structures (19) configured to adjust a longitudinally uniform spacing between the upper conveyor (6) and the lower conveyor (7) to define a foaming gap (10) corresponding to a desired outlet thickness (S) for the panel (2), and geometry variator means configured to vary the reciprocal position between the first upper portion (15) and the first lower portion (16) to modify the geometric configuration of the foaming gap (10) in the first conveying zone (C) and define a longitudinally differentiated spacing between the first upper portion (15) and the first lower portion (16) to guide and facilitate the expansion of foam generated by a mixture of reactive resins, so as to reduce and minimise the amount of expanding agent required and optimise the cellulation of the foam. A method for continuous process foaming of the panel is also provided.
