The ram housings of a volumetric metering stuffer are provided with ram seals to prevent leakage of the product being stuffed. The rams are reciprocated translatorily along substantially straight lines to prevent sidewise thrust on the seals. Cushions absorb the shock incident to the ends of the strokes of the rams and provide smooth deceleration thereof. Each ram has a clean-up cage to receive the ram when the ram is withdrawn from its housing.
