A feed unit, for example for feeding components to smoking article assembly apparatus, includes a rotary device having one or more channels (7) adapted to receive components, one on top of another, and one or more pushers (21) associated with each channel. The feed unit also has a track (14) to receive components from outlets of the one or more channels (7) and the rotary device is configured to rotate with respect to the track (14) so that components pass through the channels (7) and are pushed along the track by the pushers (21) for output from the feed unit.
