ABSTRACT:
Improved cutting device for an apparatus for the simultaneous dispensing and cutting of bands of wound material. This device is distinguished in that it comprises two independent blades located side by side at an angle, each of which corresponds to two half-lengths of the drum, whereby each of the blades is fixed to blade carriers oriented angularly in the drum and is associated with a follower roller which cooperates respectively with a fixed cam of the same profile located on each lateral wing of the housing of the apparatus, whereby said cams are offset angularly in order to permit the progressive and successive exiting of each blade and to define two cutting zones of the band of material in the apparatus while obtaining only a single clean cutting line of said material perpendicular to its lateral edges.
