Abstract
A packaging machine includes moveable spaced metering bars and guide means for supplying groups of articles from an infeed conveyor to a packaging station and is arranged to tighten a carrier blank about a group of articles while the blank and articles are moved by the metering bars and includes tightening means movable along the group of articles on each side thereof and which engage portions of the blank on each side of the group near the bottom portions of the articles by means which moves at substantially the same velocity as the velocity of movement of the group of articles and blank and which imparts a downward tightening force thereto without causing any substantial frictional dragback and which need not move in precisely timed sequence with a blank and an associated group of articles.
