The rollers (22) of the auxiliary unit are adjustable in height to facilitate the connection of the base units to the other units. The material can be moved from the base unit to the auxiliary unit or vice versa. The auxiliary unit and base unit have centring elements and fixing elements to engage with each other for connection.
