ABSTRACT:
The rounding of the backs of book blocks in a bookbinding machine is accomplished through the use of rotatable rounding rollers which acquire the book blocks from continuously moving clamping devices of a block transport system, the rounding rollers moving in synchronism with the clamping devices along a portion of the path of book block motion defined by the transport system during the rounding operation. The rotational motion of the rounding rollers against the book block sides is superimposed on movement of the rounding rollers along the book block sides in a direction transverse to the path of motion thereof. Subsequent to completion of the rounding operation, the rounding rollers are returned to their initial position along return paths which are displaced from the book block motion path and the rounding operation is performed on a book block subsequently arriving via the transport system.
