Perfected cutting device for a device for dispensing and simultaneous cutting of material rolled up in webs

A dispensing and simultaneous cutting device for perfected cutting of material rolled up in webs comprising, a hollow drum (7) with a longitudinal slot on its external periphery, a cutting blade and blade holder hinged in opposition to return means inside the drum, said blade projecting externally through a slot under the effect of rotating said drum by pulling on the material to penetrate into the material taut on both sides of the cutting device, said blade being moved according to a path given by a follower roller associated with the blade holder and cooperating with a fixed profiled cam arranged on the side plate of the casing of the device to receive said driving drum (7) and one or several stand-by rolls (R1);

• said cutting device comprises two independent blades (22-23) arranged side by side at an angle and wherein each blade corresponds to half a length of the drum, said blades being fixed on the blade holders (24-25) angularly orientated in the drum, and wherein the drum is associated with a follower roller (28-29) which cooperates with a fixed cam (10-30) of the same profile arranged on each side plate of a casing of the device, said cams (10-30) being angularly adjustable to allow the progressive and successive projection of each blade and to define the two cutting zones (ZC1, ZC2) of the material web inside the device obtaining.
