A portioning and packaging machine for pasty materials, especially food products such as butter, margarine and cheese, comprises a stationary feed tube around which a portioning head is rotated. The portioning head is formed with radial portioning cylinders receiving the material from the feed tube and pistons which are displaceable relative to the cylinders for driving the material into vertical filling tubes. The filling tubes are raised and lowered with respect to the head by a stationary cam arrangement which can also include a cam for raising and lowering a sleeve forming a packaging foil or sheet into a cup adapted to receive the portion. The sleeve picks up the sheet from a table rotating with the head and forms the cup which it carries into a cavity of a forming table in which the portion is deposited in the resulting cup.
