Abstract
A filter tipping machine wherein a drum-shaped conveyor whose peripheral flutes deliver groups of coaxial rod-shaped components of filter cigarettes and partially applied adhesive-coated uniting bands to a draping station where the uniting bands are rolled around the respective groups of components has a rolling block which is movable toward and away from the peripheral surface of the conveyor so as to roll the oncoming components ahead of the draping station to the extent which is necessary to dislodge the components and the uniting bands from the respective flutes. This enables the dislodged components to leave the conveyor by gravity and/or under the action of centrifugal force when it becomes necessary to clean the peripheral surface of the conveyor and/or other parts of the machine at the draping station. The block has a relatively short rolling surface which cooperates with the peripheral surface of the conveyor to expel the oncoming components from the respective flutes but does not cause or permit the dislodged components to reach the nearest flute. The flow of air into suction ports which communicate with the flutes is throttled during travel of such flutes past and beyond the block so as to prevent the separated components from returning into contact with the peripheral surface of the conveyor.
