In order to realize a particularly compact binding-in machine (), the pressing devices () with the firmly assigned joint forming devices () can be driven along a circulation path that essentially lies in a vertical plane, wherein the pressing plates () of the pressing devices () are oriented parallel to this plane. The pressing devices () and the joint forming devices () are simply arranged on a rotor () that rotates about a horizontal axis (), wherein the axis of rotation () of the rotor is oriented perpendicular to the pressing plates (). This significantly simplifies the infeed and the delivery of the books ().

Binding-in machine

In a binding-in machine () for pressing in and joint forming books (), the invention proposes that the delivery device () features a book gripper () with a pair of opposite joint gripping rails () that take hold of the books () in the formed case joints () and the distance between which can be varied, wherein the formed and pressed-in books () can be removed from the pressing devices () with said book gripper. The books () are reliably separated from the pressing plates () due to the inwardly directed movement of the joint gripping rails and subsequently pulled out of the pressing devices (). The gripped removal makes it possible to realize a secondary forming or stabilizing of the formed case joints and to produce a glued connection between the case and the book block.

Binding-in machine with book delivery

The invention pertains to a binding-in machine () for pressing in and joint forming books () which comprises a multitude of pressing devices () and assigned joint forming devices (), as well as devices for feeding the books () and aligning the cased book blocks () relative to the cases () and for post-forming the rounded book blocks, wherein a forming rail () is provided that acts upon the fore edge cut () of the book block, and wherein the book is supported on the spine () and/or in the case joints (). The books are laterally taken hold of by means of a book gripper (or) that moves back and forward and transfers the vertically positioned books from an upstream transfer position (or) between the opened pressing plates () of a pressing device (), wherein the books are deposited on an alignment table () with their spine () in order to subsequently align and post-form the books () within the pressing device (). A pre-formed book is gently transferred into the pressing device such that its form is preserved.

Binding-in machine with book feed

A device for backing rounded book blocks () clamped near the spine, by a pressing beam () and a slide () that accommodates the pressing beam () and can be alternately displaced along arc-shaped races () in a swinging fashion by driving means () in a height-adjustable supporting bearing () that is laterally supported against the effect of a spring element (). Members are provided for controlling () the lateral position of the supporting bearing () and for lowering and raising () the pressing beam into the starting position for its return stroke. An eccentric starting position is realized during the lowering of the pressing beam () on the spine (), in the form of a swinging position of the slide () that is offset toward the opposite side of the spine center () referred to the respective side to be backed thereafter.

Device for backing book blocks

The device comprises a delivery device (-) that delivers the additional part () into a delivery position () that is spaced apart from the book block spine (). The transfer device () comprises at least two holding elements () that move in a reciprocating fashion and the cycles of which are phase-shifted relative to one another, wherein said holding elements move in different tracks () that are offset relative to one another between the delivery position () and the book block spine () and apply the delivered additional part () onto the book block spine () after it was provided with glue. The holding elements () carry out a reciprocating turning movement about a common axis (), wherein the turning radius of at least one holding element is increased or decreased in the instant in which both holding elements () pass one another.

Device for joining additional parts to a book block spine

A book pressing machine () comprises a pressing station for pressing the book cover () on to the book block (), which pressing station includes a pressing table () and a pressing plate () movable perpendicularly to the pressing table () for all-over pressing of the book () with the book () lying flat, and comprises means () for aligning the book () in the pressing station and an endless conveyor belt () which conveys the book () in and out, the upper belt section of which rests on the upper face of the pressing table () as a support for the book (). With a view to simple and cost-effective construction a conveyor direction (F) of the conveyor belt () disposed transversely to the book spine () is provided for conveying the book () in and out with the spine () leading; a knife edge () forming the front deflecting element for the conveyor belt () is provided in the pressing table (), and a separate pressing rail (), which forms the front end-piece of the pressing plate () and performs a reciprocating horizontal movement in addition to its vertical movement (H), is provided for holding down the book cover as the pressing plate () is opened and for accelerating the book () as the latter is conveyed out.

Book pressing machine

In the case of an inner book conveying channel having mutually adjustable lateral guides and having a height-adjustable inner book support, on which inner books are fed in an upright position while being laterally supported, for operationally reliable conveying of very thin inner books an inner book support ( ) is provided with bottom lateral guides ( ), which are preferably arranged on either side and height-adjustable jointly with the inner book support ( ), and with middle lateral guides ( ), which are positioned between the bottom lateral guides ( ) and top lateral guides ( ). Said middle lateral guides are freely displaceable along vertical guides and by virtue of height adjustment of the inner book support ( ) are liftable by the bottom lateral guides ( ) into a vertically offset position.

Inner book conveying channel

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.
