Abstract: For a book casing-in machine, there is provided a method in which, while being conducted out, the books are shaped in the fold and pressed over their entire area and are held in a force-locking manner until they are deposited in the lying-flat condition. The device for performing the method has a conducting-out conveyer which takes over the book from the casing-in point and has shaping rails which engage in the fold and pressing rails which effect clasping in the region close to the fold. The device also has a book-delivery gripper which takes over the book from the conducting-out conveyer and feeds the book to pressing rollers which are driven in rotation and which roll along on the lateral faces of the book.

Abstract: A machine for casing inner books into book cases by gluing the outer end papers of an inner book to the inner surfaces of the covers of a book case, having a conveyor, which at cyclical intervals feeds successive inner books with the spine directed upwards in a vertical plane of motion to a cyclically fed book case, which is held in position in the plane of motion of the inner book, and having means for moving the covers up against the inner book and joining the end papers and book covers, is, in view of a compact design which is less expensive to manufacture, characterised by a feeding conveyor (5), which feeds the inner book (2) with the spine directed upwards to a lower receiving point and has a device (15-17) for spreading apart the outer end papers (2a) of the inner book (2), and by a gripper (21), which grasps the inner book (2) between the spread-apart outer end papers (2a) and conveys it from the lower receiving point to an upper joining point.

Abstract: A method of manufacturing a book block with a rounded or a rounded and pressed back includes adhering a first plurality of narrow retaining strips along outer leaves and back of the book block. Additional retaining strips may be applied transversely across the back of the book block in the region of the top and bottom of the back of the book block. Thereafter, the book block may be rounded or rounded and pressed. It is believed that application of the retaining strips prior to the rounding and pressing operations reduces the forces of resistance in the rounding and pressing operations.

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.
