Feeder for a tube-filling machine of the type which, in a sequence of stations (28, 29, 30) along a continuous conveyor (10), is designed to process packaging tubes (40), including filling and sealing them, and where the conveyor has a straight section (10a) to which empty packaging tubes are taken from a magazine (13, 14) by means of at least one robot device (21, 22) and are inserted by the latter into tube holders (11, 12). The feeder is designed as a beam arrangement on the robot arm and comprises at least one elongate straight beam (37, 38) and a set of tube-handling members (41) arranged on the beam. Means are provided for positioning each tube-handling member in a first position specific for each such member and a second position specific for each such member along the beam. The distance between adjacent tube-handling members in the said first position is chosen such that it correponds to the spacing between the tube holders on the conveyor, and the distance in the said second position corresponds to the centre distance between adjacent tubes in the magazine.
