Abstract: An apparatus and method for forming a rod member used to manufacture cigarette filter elements, involve an insertion device for inserting objects into and along the rod member formed from a continuous filter material supply. The insertion device includes an insertion member adjacent to the filter material supply and defining a series of receptacles about a periphery thereof. The insertion member rotates in a first rotational direction to receive the objects in the receptacles at a first rotational position and to insert the objects from the receptacles into the rod member at a second rotational position. A cleaning element is adjacent to the insertion member between the second and first rotational positions in the first rotational direction, and engages each of the receptacles upon rotation of the insertion member between the second and first rotational positions to remove residual material from the receptacles prior to the first rotational position.
