Abstract
The application of adhesive to selected non-perforated sections of one side of a running web of tipping paper in a filter cigarette making machine is carried out in such a way that the adhesive is invariably applied only to the non-perforated sections which alternate with perforated sections. To this end, the speed of advancement of the web along its path past an adhesive applicator and thereupon through a severing unit (which subdivides the web into a file of successive uniting bands to be wrapped around filter mouthpieces and plain cigarettes) is temporarily altered when a comparison of first signals denoting detection of successive perforated sections of the running web with second signals denoting the frequency of severing of the web in the severing unit indicates the need for a temporary change of the speed of the web upstream of the adhesive applicator. The latter is installed at a fixed distance from the severing unit.
