| 20100239392 | BOOK BINDING MACHINE AND METHOD FOR OPERATING A BOOK BINDING MACHINE - A book binding machine includes a collating machine, a perfect binder and a transfer device disposed between the collating machine and the perfect binder. The collating machine and the perfect binder are actuated by a common control device. In each case, one transport segment is assigned to a respective book block clamp by the control device. The control device also has a program which, if a defective or missing book block clamp is detected, actuates the collating machine in such a way that no book block is collated for that book block clamp. A method for operating a book binding machine is also provided. | 09-23-2010 |
| 20140017038 | APPARATUS FOR APPLYING ADHESIVE AND METHOD FOR OPERATING SUCH AN APPARATUS - An apparatus for applying adhesive to a book block spine has an application nozzle, a nozzle opening of the application nozzle being variable and able to be adapted to the thickness of a book block to be processed. The application nozzle has a first chamber for providing adhesive and a second chamber. A first slide is provided in the region of the first chamber for changing a width of the first chamber. A second slide is provided in the region of the second chamber for changing the volume of the second chamber. The changing takes place in such a way that, when there is a change in the width of the first chamber, the sum of the volume of the first chamber and the second chamber remains constant. The apparatus allows a strictly defined application of adhesive possible even when there is a changeover to a narrower book block spine. | 01-16-2014 |
| 20140234067 | DEVICE FOR DELIVERING PRINT SHOP PRODUCTS SUPPLIED IN A PRODUCT STREAM ON TWO SEPARATE STACKS - A device for delivering print shop products supplied in a product stream in two separate stacks contains a transport belt on which the print shop products are deposited, a first deflection roller, a second deflection roller arranged in an horizontal plane with the first deflection roller, a third deflection roller arranged below the second deflection roller, and a stationary fourth deflection roller arranged below the third deflection roller and guiding the transport belt. An actuator jointly moves the second and third deflection rollers in parallel with a horizontal plane from a first delivery position, in which the print shop products are transported to a first stop, into a second delivery position, in which the print shop products are transported to a further stop. First and second first adjustment devices change a distance between the bottom of the respective first and second product receiving spaces and the horizontal plane. | 08-21-2014 |
