Abstract
A filter tipping machine for the production of filter cigarettes has an apparatus which convolutes adhesive-coated uniting bands around groups of coaxial filter plugs and plain cigarettes while the groups move sideways through a gap which is defined by the convex peripheral surface of a drum-shaped first rolling device and the concave surface of a normally stationary second rolling device. If the surfaces of the rolling devices are contaminated or are likely to be contaminated by adhesive which is removed from the uniting bands during their conversion into tubes while the respective groups advance through the gap, the second rolling device is moved away from the first rolling device and a brush is caused to sweep along the two surfaces to remove the accumulations of adhesive. Widening of the gap and movements of the brush along the two surfaces can be initiated in response to signals which are generated by a jam detector at the inlet of the gap, by a switch which starts the motor of the filter tipping machine, by a switch which arrests the motor, and/or by a switch which is actuated by an attendant whenever the attendant feels that a cleaning of the rolling device is in order.
