Abstract: A bookbinding structure and method. The bookbinding structure is used to bind pages together in existing, commercially available binding machines. The bookbinding structure has a heat activated adhesive matrix for binding the pages. To attach a wrap-around book cover once the pages have been bound with the bookbinding structure, an adhesive on the outer surface of the bookbinding structure may be exposed by removing a release liner covering the adhesive. The book cover may then be adhered to the exposed adhesive either by a heat method or by applying pressure over the adhesive, depending on the particular type of adhesive of the bookbinding structure. The book cover may be printed with information and/or graphics prior to being wrapped around the pages of the book.

Abstract: In a process for casing a book block or paper-cover block into a cover during the manufacture of adhesively bound books, paper covers or magazines in an adhesive binding machine in which the block is transported, with a hanging-out portion, in a block clamp belonging to a transport system and is connected to the cover by gluing the back and/or the side regions, provision is made, in order to achieve an increase in quality, for the hanging-out portion (1a) of the block (1) to be aligned with the back region (2a), which is preferably predetermined by scoring, of a cover (2) which is fed in, and for the said cover (2) to be pressed against the back and/or the side regions of the block (1).

Abstract: Apparatus for manufacturing book-binding covers including a board-feeding-in system for feeding in cover boards and a back insert and a copy-feeding-in system for feeding in reference copies. A copy cylinder grips the reference copies, guides them past a glue-applying roll, and joins them to the cover boards and back insert. A tucking-in and pressing-on device folds the protruding reference-copy edges round the board edges and presses the book covers on. A feeding-out device delivers the book covers in stacks. The material flow of the book boards, back inserts, reference copies, and book covers is orientated in an ascending manner in relation to the horizontal surface on which the apparatus stands. The gain in height thus achieved compensates for the losses in height in the board magazine, in the tucking-in system, in the feeding-out device, and on the onward conveyers so that the laying-on of the cover boards takes place at virtually the same, ergonomic working height as the taking-off of the book covers.

Abstract: In a method for adhesive attachment of a cover and a binding strip on the flanks of a spine of an book block comprised of bound printed sheets, the book block is transported in a transport direction on a circulating transport device.

The cover is moved into a proper position relative to the book block spine in accordance with the cycle of the book block and in the transport direction of the book block. At least one of the lateral strip parts is loaded on a side facing away from the cover with a pressing element. The cover and the book block pass through a pressing device in order to connect the cover and the book block to one another.
