Abstract
In apparatus for manufacturing and packaging bound books a turnover device is provided for turning over alternate books fed by a conveyor from a building-in machine and leading to a stacking device where such books are accumulated in stacks and delivered for packaging. The turnover device lifts alternate books from the consecutive line of books on an in-feed conveyor, turns the lifted books 180.degree., and replaces them in the spaces left vacant when the books were lifted. The conveyor system then transports these books positioned in alternate orientation, such that when they are stacked, their spines or backbones are on alternate sides of the stack which renders each stack less high, more stable and compact and easier to handle in subsequent packaging and shipping operations. The turnover device comprises a pair of continuous belts about rotating drums where each belt is twisted through 180.degree. and the belts are situated such that a moving pocket is created between adjacent belts whose portions pass through the 180.degree. twist; the pocket transports the books through a twisted passage, while simultaneously holding and supporting the books until delivery in the turned-over s…
