DEVICE FOR DIVIDING A CONTINUOUS WEB OF WRAPPING MATERIAL INTO SUCCESSIVE SINGLE SECTIONS

摘要

The invention refers to the devices for dividing a continuous web of wrapping material into successive single sections of the same length, particularly for dividing a web of wrapping material into successive single bands used in the manufacture of filter-tipped cigarettes. These devices comprise a rotary cutting roller (1) with one or more angularly equispaced peripheral radial blades (7), the cutting edge of which is parallel to the axis of the shaft (6) for driving in rotation the said cutting roller (1). According to the invention, the blade or blades (7) are each secured to a bridge-shaped blade-carrying member (80) which by elastic deformation is elastically yieldable in the radial direction and can be completely or partly made from the skirt (2) of the cutting roller (1) or from a block added and secured to the skirt (2) of the cutting roller (1).
