ABSTRACT:
A support member arrangement for tubes in a tube filling machinery, where each support member of the machine comprises a support member part attachable to the conveyor and has a tube receiving cavity arranged generally perpendicular to the transport direction and symmetrically relative said perpendicular extension. A tube breast receiving sleeve is displaceable along an internal guide surface which is supported in the cavity in the support member and arranged for expansion and contraction. The guide surface controls the sleeve for displacement in the direction of the symmetry axis. A grip portion of the sleeve at the end thereof, facing the conveyor, grips the breast portion of the tube. The contraction and the expansion, respectively, of the squeeze sleeve is controlled by curve portions of said guide surface.
