Abstract
A web of air-permeable uniting band material for use in a filter tipping machine is advanced lengthwise by a first pair of driven rollers and a second pair of driven rollers, first through a magazine which is located between the two pairs of rollers, thereupon around a roller-shaped flanged adjustable braking device which is located upstream of the second pair of rollers, and around an adjustable curling device between the braking device and the second pair of rollers. The braking action is regulated for the purpose of subjecting the running web to a predictable curling action. This enhances the quality of filter cigarettes wherein the tobacco-containing and the filter material-containing parts are connected to each other by adhesive-coated uniting bands constituting sections of the thus treated web.
