Transport nozzle for a device for the production of filter rods for the tobacco processing industry and apparatus for the production of filter rods for the tobacco processing industry

摘要

The present invention relates to a transport nozzle (17) for a device for the production of filter rods for the tobacco processing industry with a channel (33, 34) through which an endless strand of filter tow (3) is conveyed and which is guided by the transport nozzle (17) in that, for conveying the filter tow (3), an air flow is conducted through the transport nozzle (17) to the channel (33, 34), and the transport nozzle (17) has an air inlet (17a) through which the air flow into the transport nozzle (17 ), an expansion chamber (40) connected to the air access inlet (17a), a distribution chamber (41) connected to the expansion chamber (40) via an intermediate wall (42) having at least one opening (44), and an annular one Gap (43) connected on one side to the distribution chamber (41) and on the other side to the channel (33, 34), wherein the distribution chamber (41) is formed such that the volume of the distribution chamber (41) corresponds to at least half the volume of the expansion chamber (40).
