发明名称 Newspaper bagging method and apparatus
摘要 Multiple section, quarter-folded bulky newspapers in flat form are inserted into and sealed within transparent polyethylene bags without first rolling or folding the newspapers into smaller bundles so as to present generally flat, weather-resistant, tamper-deterring packages which may be readily stacked, shipped and otherwise handled. The newspapers are delivered seriatim to an inserting station at which the leading newspaper is fed into the open mouth of the topmost bag in a wicketed stack of the bags, whereupon the bagged newspaper package tears free from the wicket and advances downstream to a heat sealing mechanism. Just prior to passing beneath the heat sealer, a marginal, entry end portion of the bag is folded back on top of the package so that, as the package passes under the sealer, the marginal portion is fused against the top wall of the bag while the encapsulated newspaper serves as a heat sink, thereby securely closing the bag mouth and completing the sealed package. The newspaper contents of the package may be thereafter readily removed by tearing open the bag and discarding the same.
