  • the conveyor segments 14 according to the in figure 5 illustrated embodiments formed.
  • the additional receiving trough 18 positions the rolled rod-shaped articles at the end of the rolling channel 25 in the receiving troughs 18 of the leading conveyor segment, with the winding end of the wrapping strip being aligned in a predetermined position at the exit of the rolling channel 25 .
  • the roller conveyor 23 is guided between the input-side roller 21 and the output-side roller 28 .
  • the roller belt 23 is conveyed at a higher speed compared to the transport speed of the rod-shaped articles in the receiving troughs 12 (cf. figure 5 ) the conveyor drum 10, in a corresponding manner according to the embodiments in the Figures 1 to 4 . Due to this, in particular low, higher differential speed or overspeed of the roller conveyor 23, the rod-shaped articles, such as assembled segment groups, are pushed forward out of the trough 12 in the conveying direction of the conveyor drum 10 (cf. figure 5 ) rolled, whereby the respective wrapping strip is wrapped around the rod-shaped article.
  • the rod-shaped articles are wound within the rolling channel 25 in such a way that the winding end in the receiving trough 18 of the leading conveyor segment 14 is in the trough surface of the receiving trough 18 in contact with the trough surface, so that when the rod-shaped articles are transferred from the conveyor drum 10 to a subsequent conveyor drum 100, the winding closure of the rod-shaped articles after the transfer to the conveyor drum 100 is on the outside or on top.
  • a roller conveyor 110 is also arranged on the (second) conveyor drum 100 in order to produce the rod-shaped articles arranged on the conveyor drum 100 with a completely closed winding closure.
  • the second roller conveyor 110 makes it possible, even with thicker wrapping strips, to firmly bond and press on a wrapping strip that is (initially) not completely glued and not in contact with the rod-shaped article or its winding end.
  • the roller conveyor 110 has a roller 111 on the input side and a roller 112 on the output side.
  • a roller belt 113 is guided over the rollers 111, 112, so that the section of the roller belt 113 guided between the rollers 111 and 112 and the conveyor drum 100 form a roller channel 115 through which the rod-shaped articles are conveyed.
  • the roller conveyor 113 is conveyed back from the roller 112 via a further, preferably driven, roller 116 to the roller 111 on the input side.
  • a tension roller 114 is arranged on the roller belt 113 in order to tension the roller belt 113 .
  • the rod-shaped articles are arranged on the conveyor drum 100 in such a way that, for example, the open winding end of the wrapping strips is on top or on the outside on the Conveyor drum 100 is arranged.
  • the rod-shaped articles are then conveyed into the rolling channel 115 with the winding end of the wrapping strip pointing outwards.
  • the conveying speed of the roller belt 113 is set in such a way that when the open winding end of the wrapping strip for the rod-shaped articles comes into contact with the roller belt 113, the rod-shaped articles in the roller channel 115 are not moved and pressure is thereby exerted on the open, outside or external winding end of the wrapping strip causes whereby the open wrap end of the wrapping strip is fully connected to the stick articles.
  • the conveying speed of the roller conveyor 113 corresponds to the conveying speed of the rod-shaped articles not moving on the conveyor drum 100 .
  • the roller belt 113 it is possible for the roller belt 113 to be moved at a lower (differential) speed than the conveying speed of the rod-shaped articles on the conveying drum 100 before entering the roller channel 115 . Due to a (negative) speed difference between the roller belt 113 compared to the conveying speed of the rod-shaped articles on the conveyor drum 100 before entering the roller channel 115, the rod-shaped articles in the roller channel are rolled out of the receiving troughs of the conveyor drum 100 in the opposite direction to the conveying direction of the conveyor drum 100, as a result of which the open winding end of the wrapping strip is closed by a further rolling process by means of the roller conveyor 110. At the end of the rolling channel 115 the rod-shaped articles rolled (backwards) in the rolling channel 115 are arranged in a trough of the conveyor drum 100 .
  • a further embodiment of a drum arrangement T is shown schematically.
  • the roller belt conveyor 20 also has a tiltable or pivotable roller 29 for the roller belt 23 guided over the rollers 21, 28, 22, whereby the tilting or pivoting of the roller 29 changes the position of the roller belt 23 in relation to that on the conveyor drum 10 conveyed rod-shaped article 30 is moved to the left or right, ie along the longitudinal axis of the rod-shaped article 30, whereby the roller conveyor 23 for the rolling of the rod-shaped article 30 with the respectively attached wrapping strip 40 is or is exactly aligned.
  • the roller 29 is arranged on the drum arrangement T by means of a corresponding movable holder.
  • a control unit (not shown here) with a sensor for detecting the position of the roller belt 23 in the roller belt conveyor 20 is also provided transmits the detection signals to a corresponding evaluation device.
  • the evaluation device which in particular carries out a target/actual value comparison for the detection signals, the holder for the roller 29 and thus the roller 29 is tilted or pivoted, for example by means of a drive, if a predetermined target value is exceeded, about the roller conveyor 23 guided over the roller 29 in its initial orientation or in a predetermined orientation with respect to the rod-shaped articles 30 moved with the roller conveyor 23.
  • the roller belt conveyor 20 has a tension roller 127 that is mounted so that it can pivot.
  • suction roller 50 is provided on the conveyor drum 10 upstream of the roller conveyor 20 and a feed drum 60 is provided upstream of the suction roller 50 for feeding and transferring the rod-shaped articles 30 to the conveyor drum 10 .
