Abstract
A flexible membrane (54) confines the rod-like articles in a transition zone (10) (which may be the filling head of a tray filler). The membrane is extended or retracted under tension in response to pressure of articles in the zone. The amount of extension or retraction is used to generate a signal which controls a conveyor (18) feeding articles to the zone (10) or a conveyor (38) taking articles away from the zone (e.g. in trays 36). The signal may be generated by a rotary potentiometer (64) rotatable with a spiral spring (62) to which the membrane (54) is connected.
