Abstract (en)
The present invention relates to a method for making fibre-box like containers and related covers, which comprises the steps of making a tubular body, (1) including superimposed sheets of a paper material, and stretching this tubular body by rollers (2) arranged at corner portions thereof, in order to cause the tubular body to assume a substantially parallelepipedal shape. The main feature of the invention is that the method further comprises the steps of: deforming, by a mold, (11,21) an axial end of the tubular body, so as to provide a substantially parallel edge band recessed with respect to the side surface of the tubular body, inwardly bending the corner regions in order to remove the material excess and, finally forming a cover having the same peripheral extension as the box-like body. <IMAGE>
