Abstract:
A stack of laminar material, such as corrugated cardboard or the like, for forming packages, such stack (S) comprising full panels (P) having a predetermined total length (W) and formed with transverse creases (C) along which the full panels (P) are folded in accordion-like pleats. The stack (S) comprises at least one longitudinal cut (T) on each full panel (P) to form at least two transversely adjacent stacks (S, S'') of partial panels (P', P'') having respective partial widths (W', W''), which are less than the total width (W). The at least one cut (T) is incomplete, so that each partial panel ((P') of a respective stack (S') and the partial panel (P'') of the stack (S'') adjacent thereto will have at least one connecting section (J) therebetween, having a predetermined minimum length (H), for holding the partial panels (P', P'') of the adjacent stacks (S', S'') together, to thereby keep the adjacent stacks (S', S'') substantially aligned while facilitating the separation of each of the partial panels (P', P'') as they are unwound by a pulling action from each adjacent stack (S', S''). A method of using a stack (S) of laminar material in a loading unit of a plant for making box packages is also provided.
