Abstract
A packaging machine comprising a rotary body having blank bottom forming radial mandrels so arranged as to be successively stoppable at a plurality of process stations including a blank feed station, a feeder for fitting a tubular blank having a square or rectangular cross section around the mandrel stopping at the blank feed station to feed the blank to the mandrel, and a collector for collecting paper particles adhering to the blank to be fed by the feeder. The feeder has a pair of guide rails positioned on opposite sides of and extending in parallel to a phantom line extending outward from the mandrel stopping at the blank feed station. The collector has a tubular collecting cover enclosing the guide rails. The cover is formed with an air outlet covered with a filter. A suction device applies suction to the air outlet.
