ABSTRACT:
A book package blank and method and machine for its fabrication by a continuous process. A cardboard web (2) of thin and solid pulp is pulled from a reel. The web is gently corrugated between splined rollers (4) to guide the folding of the cardboard around one or more books. The final separated blank is a rectangular sheet of double layered cardboard having bending lines along its two opposite edges between the two superimposed layers. The layers are attached to each other with the exception of two opposite flaps (17) defined by slits (16) in the topmost layer and detached from the bottom cardboard layer, the width of the flaps corresponding to that of the book(s).
