Abstract
A cigarette maker or a filter rod making machine wherein a continuous rod-like filler is advanced by an endless foraminous belt conveyor toward a wrapping or draping unit and a web of wrapping material is advanced toward the unit to be draped around the filler. In order to ensure that the leader of a fresh web properly enters the wrapping station, the path for the web is monitored and the belt conveyor for the filler is moved toward the path of the web when a monitoring device detects the leader. If the cigarette maker or the filter rod making machine is designed to simultaneously produce and drape two or more discrete fillers, the paths of the webs are monitored independently of each other and portions of the respective belts are moved toward the oncoming leaders of the webs whenever the respective monitoring devices signal the arrival of leaders in preselected portions of the paths.
