Abstract: A magazine for the maturation of cakes of synthetic foam material, for a plant served by a conveyor belt bringing the cakes for distribution in the magazine, and by an overhead crane with a gripper intended for lifting a cake from the belt conveyor, for shifting it laterally and for depositing the same into a maturation space, which comprises stands arranged parallel to and at the side of the belt conveyor; each stand comprises a frame which supports a fixed lower shelf whose width and length are adapted to the width and length of the cakes to be received, and above the fixed shelf, at vertical mutual distances somewhat greater than the height of the cakes to be received, a plurality of movable shelves for receiving the cakes; each movable shelf is shiftable between a working position, in which it constitutes a surface whose width and length are adapted to the width and length of the cakes to be received, and a rest position, in which it leaves free the access from above to the shelf lying below.

Abstract: A process and apparatus for marking an article made of foam material whenever during its manufacturing process some irregularity has occurred. As a consequence of having ascertained an irregularity in some operational parameter, after the introduction of the reactive mixture in the inner cavity of the lower shell of the mould and as long as the mould is still open, to a part of the inner cavity of the upper shell of the mould is applied a mark formed by a dyestuff resistant to the processing conditions, physically and chemically compatible with the formed article and capable of adhering thereto when, during its expansion, the article reaches to contact the marked part of the inner cavity of the upper shell of the mould. The marking operation can take place automatically by action of an equipment comprising an ejector arranged for spraying towards the internal cavity of the upper shell of the open mould the dyestuff intended to form the mark.
