ABSTRACT:
A method and device for the production of filter tip bands for ventilated cigarettes, according to which a continuous strip is advanced along a pre-set feed path, an adhesive substance is applied to the strip using a gumming device, defining on the strip itself a periodic succession of gummed areas alternated with non-gummed areas and the strip is cut using a cutting device according to transversal lines at pre-set intervals defined by the gummed areas to produce the bands. A control device controls the timing between the gumming device and the cutting device. The timing is compared with a pre-set value and is corrected, using a correction device in order to eliminate any variation of the pre-set value.
