ABSTRACT:
The invention refers to an apparatus for dividing a continuous web of material into successive single sections, particularly for dividing a web of covering material into successive single bands used in the manufacturing of filter-tipped cigarettes. Such an apparatus comprises a rotary cutting roller with one or more peripheral radial knives which are angularly spaced apart from each other and have their cutting edge parallel to the axis of rotation of the cutting roller. According to the invention, each knife is secured to a knife holder consisting of a bridge-like member having an inherent elastic compressibility in the radial direction, which in the fashion of a beam with a plurality of supports is supported by the cutting roller on two end supports and on one or more intermediate supports. The supports are preferably adjustable in the radial direction, and particularly consist of wedges. The inherent elastic compressibility of the knife holders is obtained by means of slots or slits made in the said knife holders, and which are preferably orderly arranged in at least two radially spaced apart parallel rows extending along the length of the knife holders, and being offset from each other in the longitudinal direction.
