Improvement to protection covers of parallelepipedal panels constituted by idoneous parallelepipedal boxes maked in an idoneous corrugated cardboard in which, one of the relatives bigger faces results longitudinally divided in two opportune parts (13a and 13b) ending at their free extremity with corresponding thickness edges (14a and 14b) complementarly between them which in the position of closure results reciprocally superposed not let alone disposed long a respective longitudinal axis of the relative face so reconstructed, the introduction between the surfaces which that in said thickness edges (14a and 14b) results between them opposed, of an opportune glue (E) permits to obtain the reciprocal and definitve fixing of said two parts (13a and 13b) and then the reconstrction of the relative bigger face. |
