Furthermore, it is possible to use the feeding unit in different configurations of the rod manufacturing apparatus. Among others, it is possible to use the feeding unit to manufacture the rods of a continuous rod in which the beads are unevenly spaced.
  • An example filter rod R shown in a cross-section in Fig. 1 comprises four objects in the form of beads C situated among the fibres F of the filter material.
  • the beads C are placed along the axis k of the filter rod R and centrally relative to the axis k.
  • Fig. 2 shows a filter rod R' comprising the segments S1, S2 and the beads C placed in the spaces between the segments.

  • the apparatus 1 for manufacturing the rods R is provided with feeding unit 4 for feeding a material 2 (generally filling material) wherein the material strip 2 is subjected to processing.
  • the apparatus 1 comprises a feeding unit 5 arranged to feed the beads C, a forming unit 6 and a cutting head 7.
  • the apparatus 1 comprises a guiding unit 8 for material strip guiding and preliminary material compression, a compressing unit 9 for strip compression and continuous rod CR forming. Whilst forming the continuous rod CR is wrapped with a band of a wrapping material P fed by a wrapping material feeding unit 10.
  • the apparatus 1 is provided with a forming unit 12 for final forming and lengthwise gluing of the continuous rod CR.
  • the guiding unit 8, the compressing unit 9 and the forming unit 12 constitute together a forming apparatus for forming the continuous rod CR.
  • Fig. 6 shows the feeding apparatus 5 comprising a feeding wheel 20 and five feeding units 21 feeding the beads C to the transporting pockets 22 situated on a circumferential surface 23 of the feeding wheel 20.
  • the number of feeding units depends on the quantity of beads which are to be placed into the continuous rod CR.
  • the feeding unit 21 comprises a supply channel 24, a pushing mechanism 25 and a transferring wheel 26 with the rotational axis m.
  • the pushing mechanism 25 comprises a body 27 which in the embodiment shown has the shape of a cylinder. In the body 27, on its lateral surface 28, there are situated a holding pocket 29 and a transferring channel 30 extending from the holding pocket 29 towards the transferring wheel 26.
  • the transferring channel 30 is situated diagonally to the generator of the body 27 and tangentially to the transferring wheel 26, whereas the transferring channel 30 is directed in accordance with the direction of rotation of the transferring wheel 26 marked with an arrow.
  • the pushing mechanism 25 comprises a movable pushing element 31 having a pushing edge 32.
  • the pushing element 31 has the form of a plate which may be flat or may be shaped as a sector of a cylindrical surface.
