The invention relates to a device relating to a feeder tube, i.e, a conveyor intended for bulk product, in particular a feed-out device, which comprises a cylindrical drum or tube (2) in which there are accomodate d inlet openings (8, 18) distributed along the length of the tube, a screw conveyor (3) disposed coaxially with the tube within the tube, means for rotating the tube about its axis, means for rotating the screw conveyor relative to the tube, means for moving the feeder tube in the lateral direction, and activators (9A, 9B, 19) for the bulk product which activators are disposed on the tube in association with the inlet openings and form projections on the outer side of the tube. Each inlet opening, regardless of the direction of rotation of the tube, has at least one portion (10A, 10B, 20A, 20B) which is limited in the direction of rotation by a hole edge (11A, 11B, 21A, 21B) without an activator, but which portion, at the rear end of the said portion, is limited by an activator (9A, 9B, 19).
