Abstract: A shaping part for producing books with round spine includes a frame (3, 5, 7, 10), which defines an essentially rectangular inner space, and in the inner space of which a plurality of vertically adjustable lamellae, whose orientation at right angles to the plane of the frame is predetermined by the frame, are arranged next to one another. Any desired profile surface, preferably in the form of a radius, can be formed by a suitable displacement of lamellae located next to one another. To absorb strong normal forces during pressing, the lamellae are braced against one another. The lamellae can be heated by contact with the heated carrier body for preforming the spine of books. The profile surface of the shaping part may be concave or convex.

Abstract: A sheet feeder for use in a book assembling machine comprises a magazine having a movable base which defines a support plane for a stack of folded sheets. The feeder also includes a pneumatic separator, which creates a gap between a corner of the lowermost sheet of a stack in the magazine and the next adjacent sheet, and a device for injecting air into the thus formed gap to produce an air cushion. The movable magazine base functions as a conveyor to move, with the assistance of the air cushion, the leading edge of the lowermost sheet in the stack in a planar manner to a withdrawal conveying system where the sheet is engaged and subsequently pulled from the magazine. The withdrawn sheet moves, under the influence of a transfer mechanism in one embodiment, into registration with an assembly conveyor.

Abstract: In a process for the manufacture of a book, wherein an adhesive is applied to the side faces of an inner book, the inner book is subsequently cased into a book cover and the book cover folds are shaped by the application of heat and pressure, adhesive is additionally applied to the book cover in the regions which are to be formed into the folds before the joining together of the cover and inner book and, optionally, the fold regions of the book cover and/or inner book are heated before the application of adhesive.

Abstract: The order in which printing work products, such as finished books, book blocks and other similar objects, are transported is rearranged intermediate serially arranged entry and discharge conveyors. In a destacking mode of operation, stacks of products are positioned at an intermediate destacking station and the product which is uppermost in the stack is separated from the stack and delivered onto the receiving end of the discharge conveyor, the receiving end of the discharge conveyor being caused to move vertically in steps so as to remain in position to receive individual products as the stack height is reduced.

Abstract: In the manufacture of a book, the book consisting of a cover and an inner book, the book cover is permanently shaped by the formation of folds in the articulation region thereof prior to being joined to the inner book. In the course of forming the folds in the cover, the covering material thereof is caused to undergo plastic flow and to be shaped so that beneficial stresses are created in the fold defining regions. The back of the cover may also be permanently shaped substantially simultaneously with the formation of the folds.

Abstract: Continuously accumulating printing works products are transported, over a comparatively long distance in a manner which consumes minimum manufacturing facility floor space, by being serially fed to clock-pulse controlled grippers of a continuously driven conveyor. The grippers grasp the products in the area of their leading edges and subsequently transport the products in tile-formation over a defined distance to delivery apparatus.

Abstract: Apparatus for rounding the spines of book blocks comprises rounding elements that act on the sides of the book block, the action of these rounding elements being due to a defined rotation and pressure, the rounding elements consisting of rounding segments which are drive-rotated by actuating mechanisms and can be moved vertically to thereby execute rolling movements on the sides of the book block. The vertical movement of said rounding segments are superimposed on their rotation in a manner such as to compensate for the vertical movement of the book block generated as a consequence of the rotation.

Abstract: A feeder station for apparatus for collating printed sheets includes a mechanism for imparting motion to individual sheets prior to the time the sheets are engaged by a pusher mechanism which propels the stack of collated sheets being formed along a conveyor. The mechanism for imparting motion to the individual sheets in the feeder station contacts the sheets within a region which is directly aligned with the path the engaged portion of the sheet travels in moving from a feed magazine to the feeder station under the influence of a gripper device, the sheet thus being transferred directly from the gripper device into contact with the motion imparting mechanism.

Abstract: The backing of a previously rounded book block is accomplished, while the book block is clamped between oppositely disposed gripping jaws, by subjecting the spine region of the book block to composite forces resulting from imparting a swinging motion along an arcuate path to a pressing beam carrier, to cause the pressing beam to bend the book block sheets outwardly away from the center line of the block, and superimposing tangential sliding motion on the pressing beam as it acts on the book block in the region adjacent the edges of the spine to thereby controllably form creases in the opposite sides of the block.

Abstract: Printing works products, book blocks having a spine for example, are transferred from a feed conveyor to a receiver with selected products being rotated through an angle of 180.degree. during the transfer. The products to be rotated are frictionally engaged, slowed to a standstill during a first phase of rotation and thereafter accelerated and discharged when rotation is completed. The synchronized first phase of rotation and arresting of product motion is controlled such that the center of gravity of the product will be located approximately in alignment with the axis of rotation when rotation through an angle of approximately 90.degree. is completed.

Abstract: A delivery system for receiving book blocks discharged from a book-sewing machine on a transverse stack conveyor, the book blocks on the transverse stack being supported on their front edges and thus being vertically oriented, and rearranging the book blocks so as to be horizontally oriented. The delivery system subsequently reorients the horizontally arranged book blocks and collects the reoriented book blocks into stable stacks.

Abstract: In a book binding operation, opened covers are brought into alignment with moving book blocks by a feed system which applies a pneumatic hold-down force to the moving covers. This hold-down force provides for a braking effect which varies as a function of the characteristics of the cover, the braking effect minimizing the chances of overshoot. The hold-down force also provides a stiffening effect, in the direction of cover movement, which varies as a function of cover thickness and minimizes the possibility of crushing.

Abstract: A book cover formation machine has feeder stations for the cover cloth and cover boards, a glue-application station for the cover cloth, and an assembly station for mating the cover cloth and cover boards. The machine also has a turn-in station with turn-in elements for folding the head and foot flaps over the cover-board edges in a first plane, and for folding the lateral flaps over the cover-board edges in a vertically displaced second plane. The turn-in station is a separate mechanism juxtapositioned to the assembly station. The functions of assembling the cover cloth and boards, of executing the head and foot flap turn-ins, and of executing the lateral flap turn-ins, are coordinated such that all functions within a cycle are performed on different book covers simultaneously.
