A newspaper edition is assembled by successively feeding folded inner sections into each of a series of open outer sections passing therebeneath in a continuously moving line of conveying buckets. Each bucket is provided with mechanism for grabbing the first section fed thereinto to prevent rebounding, a set of vacuum-operated suckers which part the folds of the section, and a pair of dividing fingers which move as a unit into the part between the section folds and thence away from one another to open the section in cooperation with the suckers. A special vacuum control system which utilizes the movement of the buckets to effect opening and closing of a series of vacuum ports alongside the path of travel of the buckets assures that uninterrupted vacuum pressure is supplied to the suckers of each bucket for a substantial period of time, and an ejector in each bucket discharges the edition when the sections thereof have been completely assembled. A misfeed system senses when the edition of any bucket fails to receive a section and activates the ejector of such bucket to discharge the incomplete edition at a special collection point. |
