Device for dividing a continuous web of wrapping material into successive single sections

A device for dividing a continuous web of wrapping material into single successive sections of a same length, comprising:

• a driving shaft having a longitudinal axis of rotation;
• a rotary cutting roller having a skirt fixed on said shaft;
• a peripheral radial blade having a cutting edge located outside the periphery of said roller, extending parallel to said axis;
• and
• a blade-carrying member for said blade fastened to said blade, formed of a separate piece, said skirt having a cavity therein for each blade-carrying member, extending through said skirt in a direction parallel to said axis, said skirt having a portion over said cavity, said blade-carrying member being fixed to the portion of said skirt over said cavity so that said portion of said skirt is elastically yieldable in a radial direction through said cavity toward said axis.

• a peripheral radial blade having a cutting edge located outside the periphery of said roller, extending parallel to said axis;
• and
• a blade-carrying member for said blade, said blade-carrying member being fixed to said skirt and fastened to said blade, being formed as a separate piece, and having a profile which has one of an S-shaped cross section and a Z-shaped cross section when viewed in an orientation with said cutting edge and said axis in a vertically extending plane.
