Device for rounding and backing book blocks

Abstract

A device for rounding and pressing book blocks with a conveying device for the book blocks. The device includes rounding rollers, pressing jaws or similar clamping elements, which are displaceable relative to one another, which act to receive the book block and act with a predefined force upon the book block. The device automatically adjusts the clamping elements to different formats of the book block and, in the event of deviations in the book block thickness, the clamping elements are displaceable relative to one another via articulately connected levers. The levers function to clamp the book block via an operating cylinder acting upon the free ends of the levers and automatically aligning the book block. The point of rotation of the levers being displaceably mounted in a guide aligned with the center of the conveying device of the book block.
