A packaging machine which includes article buckets and leaflet clamps mounted on the buckets, each clamp having a spring loaded jaw which, in the open position, allows a leaflet to be inserted between the jaw and bottom plate of its respective article bucket, and, in the closed position, is effective to clamp a leaflet between the jaw and bottom plate to deflect a portion of it into the exit end opening of the bucket. Means are provided for opening the clamp jaw, inserting a leaflet between the open clamp jaw and bottom plate, closing the clamp jaw to clamp the leaflet and opening the clamp jaw to allow the leaflet to be carried into a carton by the article as it is transferred from the article bucket to the carton.
