Abstract
The novel pre-folding machine for book covers and/or wrappers, has two symmetrical units each provided with two parallel axes on which marking disks and counteracting cylinders are installed. One of the two symmetrical units is fixed, while the other is positioned on guides or rails that extend in parallel to the shafts on which the disks and cylinders are supported and it can be translated by way of a screw, in order to adapt the distance between the marking disks to the book thickness. The machine is also provided with two pairs of flap folding pliers, each one with two wings. One of the wings is fixed and coplanar with the sheet and serves as counteracting element for the other wing that rotates by approximately 180° folding the cover flap around the marking carried that was carried out just upstream by the disks of the two symmetrical units.
