Method and apparatus for the intermediate storage of printed products arriving in an imbricated product formation such as newspapers, periodicals and the like

摘要

Printed products delivered in imbricated product formation by a conveyor having individually releasable grippers are deposited upon a belt conveyor also in imbricated product formation. This imbricated product formation is delivered to a turning device in which the printed products are singled by acceleration and are also inverted. After leaving this turning device, the printed products are conveyed against a fixed stop. After impinging upon this stop, the printed products fall upon a belt conveyor, respectively upon an already formed imbricated product formation. In this imbricated product formation the leading edges are exposed, just as they are in the arriving imbricated product formation. However, the now leading edges are formed by those edges of the printed product which formed the trailing edges in the arriving imbricated product formation. Furthermore, in the newly formed imbricated product formation the originally upper side of the printed products now lies on the underside. The newly formed imbricated product formation is delivered in "underfeed" to a winding mandril and is wound up on the latter to a compact wound product package. When this imbricated product formation is unwound from the package, an inversion of the corresponding imbricated product formation suffices to obtain an imbricated product formation in which the printed products have the same position as in the arriving imbricated product formation.
