<p>A packaging machine includes movable spaced metering bars (40) and guide means (49, 51) for supplying groups of articles (B) from an infeed conveyor (47, 48) to a packaging station and is arranged to tighten a carrier blank about the group of articles while the blank and articles are moved by the metering bars. The machine includes tightening lugs (L) which engage portions of the blank on each side of the group and which impart a downward tightening force without causing any substantial frictional drag thereto. The tightening lugs are constructed and arranged so that they need not move in precisely timed sequence with a blank and an associated group of articles.</p> |
