Abstract:
A process for manufacturing covers for books and the like, characterized in that it comprises the operations of:arranging a plurality of sheets (3) of card having overall dimensions which are greater than those of the covers to be produced and having a central aperture (8) with a substantially elongate rectangular shape and dimensions which are greater than those of the spines of the covers to be produced; feeding these sheets (3) in series to a conveyer (4, 5) which can entrain and guide this series of sheets (3) in a direction parallel with the aperture (8), supporting these sheets such that a central portion of the lower face around this aperture (8) is left free; applying a first layer (14) of adhesive to a central strip of the lower face of each sheet (3) about the central aperture (8); applying to this first layer (14) of adhesive a portion of a flexible strip (19â€²) which is wider than the apertures (8) in these sheets (3); applying a second layer (33) of adhesive to a central strip of the lower face of the portion of the flexible strip (19â€²) applied to each sheet (33); applying to this strip (33) of adhesive a strip (36â€²) of card or the like which is narrower than the apertures (8) in the sheets (3); and then shearing the ends of each sheet (3) along lines (L1, L2) which are parallel with one another and are perpendicular to and intersect the central aperture (8).
