ABSTRACT:
This invention relates to a cutting device for severing a continuous web into a plurality of individual segments, particularly into bands for connection of filters to cigarettes, by supporting the end portion of the web on a rotating supporting drum and by cutting the segments from the end of the web on the supporting drum by means of a web-cutting blade that is cyclically moved on a plane which is transverse to the web and substantially parallel to the axis of the supporting drum, so as to effect a transverse progressive cut in the web from one longitudinal edge to the opposite longitudinal edge thereof. According to the invention on the supporting drum there are mounted a plurality of web-cutting blades movable parallelly to the axis of the drum, angularly equi-spaced around the circumference of the supporting drum and actuated so as to effect cyclically, at the angular position or interval on the circumference of the supporting drum, where the cut is to be performed, an extension or cutting stroke through the web from a laterally-retracted start position from one side edge of the web to at least the opposite side edge of the web, and a retraction stroke back to the start position.
