  • a stop ring is fixedly attached to the free end face of the push-in drum remote from the strand side, on which the end face of the filter rods inserted longitudinally axially into the circumferential troughs come to rest in order to align them.
  • the end faces are covered by the stop ring, so that it is not possible to inspect the front end faces of the filter rods on the push-in drum.
  • the object of the invention is to provide a device and a method with which rod-shaped articles conveyed transversely axially can be inspected from the front in a machine in the tobacco processing industry with a reduced overall effort.
  • rod-shaped articles can thus be inspected on the push-in drum and, if necessary, ejected from the product flow with an ejection device provided on the push-in drum if an end face is found to be imperfect.
  • the inspection area free of the alignment element can be created by partial removal of the alignment element from the push-in drum in a circumferential area as a result of the relative movement according to the invention.
  • this can advantageously be achieved by using an endlessly circulating traction means, in particular a band, belt or chain, as the alignment element.
  • the aligning element is arranged in a stationary manner or fixed to the machine or location, so that the aligning element does not rotate with the push-in drum.
