Abstract

The present invention relates to a concave product or container (II) or (II'), comprising at least two layers (a) and (b) of cellulose-based material, one of said layers (a) is continuous and the other layer (b) is discontinuous, said layers being reciprocally coupled and partially overlapped and glued, between them at least in the partial overlapped zone (s) there is interposed: - a pressure or temperature activated glue/adhesive layer (c'), preferably a pressure or temperature activated glue/adhesive layer (c') of a biodegradable thermoplastic material, or - a thermally or pressure activated thermoplastic material layer (t), preferably a thermally or pressure activated thermoplastic material layer (t), wherein said material is biodegradable, as well as semimanufactures thereof and the processes of preparing them.

Abstract

A continuous cutting apparatus (10) for cutting a material, in particular a paper material, which is fed in form of sheet or roll. The apparatus (10) comprises a support frame (20) and an alternate cutting assembly (50) for cutting the sheet or roll being fed. The apparatus (10) is characterised in that said alternate cutting assembly (50) comprises a guillotine cutting device (53) of the swinging type, which accompanies the paper material to be cut along a tract of its path with a speed that is equal to the feeding speed of the sheet or roll during its movement through the cutting apparatus (10) itself.
