An apparatus and a method for the preforming and rounding of a book block. A support strip is arranged at an adjustable loading height for accommodating a fore-edge of the book block to be rounded. A transport device transports the book block at the loading height toward the support strip. A preform press is adjustable in a vertical direction above the back of the book block and includes at least two preforming tools. A rounding device including two rounding rolls driven in opposite directions for rotation around parallel rotational axes clamps the book block between the two rounding rolls for rounding the book block. At least a first drive is connected to at least one of the preforming tools to displace at least one of the preforming tools in a longitudinal direction extending parallel to the rotational axes to change a spacing between the preforming tools in the longitudinal direction.

The present invention relates to round corner cutting machine that comprises 5 pairs of suckers (116), each pair of sucker (116) grips single book and middle sucker (116) being located between pairs of sucker (116) that grip middle book. Here, position of each pair of sucker (116) is adjusted by adjusting position of guide blocks though adjustable links (107, 108). Further, distance between suckers (116) of each pair is adjusted by sliding the sucker cups (113) 10 within slot (112) of guide block so that according to size of books, the position of sucker is defined such that each book is gripped by one pair of sucker. After gripping, each pair of sucker (116) is separated linearly so that books are separated from their partition line. Said separated books are conveyed to back stopper assembly (3) where books are properly positioned and then 15 corner cutting assembly carry the corner cutting of books.
