1. A binding-in machine for pressing in and joint forming books having a case, a book block with a fore edge cut and a spine, the machine including devices for aligning the book block relative to the case, comprising:
a multitude of pressing devices that respectively feature a pair of opposite pressing plates, the distance between which can be varied in order to exert full-surface pressure upon the sides of the book, and
a case joint forming device provided with each of said pressing devices including a pair of opposite heated joint forming rails, the distance between which can be varied in order to form case joints on the books, said pressing devices with the case joint forming devices being driven such that they circulate along a closed path that essentially lies in a vertical plane, said pressing plates being oriented parallel to this plane.
2. The binding-in machine according to claim 1, wherein the joint forming rails of the case joint forming devices are always oriented transverse to the transport direction of the pressing devices.
3. The binding-in machine according to claim 1, wherein the pressing devices with the case joint forming devices are arranged on a rotor that is rotatable about a horizontal axis, said axis of the rotor being oriented perpendicular to the pressing plates.
4. The binding-in machine according to claim 1, wherein the pressing devices with the pressing plates can be located in an open position, a guiding position andor a closed or clamping position.
5. The binding-in machine according to claim 4, wherein a format adjustment to the book thickness is carried out during the positioning.
6. The binding-in machine according to claim 4, wherein at least a holding force can be exerted between the pressing plates in the closed or clamping position.
7. The binding-in machine according to claim 1, wherein the joint forming rails of the case joint forming devices can be actuated such that they form, hold andor release the case joints.
8. The binding-in machine according to claim 7, wherein the joint forming rails are spaced apart from the book spine by a large distance in the release position.
9. The binding-in machine according to claim 4, wherein the pressing devices and the case joint forming devices can be opened and closed above the book center.
10. The binding-in machine according to claim 7, wherein the pressing devices and the case joint forming devices can be opened and closed above the book center.
11. The binding-in machine according to claim 1, wherein the pressing devices with the case joint forming devices are driven intermittently.
12. The binding-in machine according to claim 7, wherein the pressing devices with the case joint forming devices are driven intermittently.
13. The binding-in machine according to claim 11, further including work stations for feeding, aligning, post-forming, pressing in andor delivering the books arranged along the circulation path.
14. The binding-in machine according to claim 13, wherein a feeding and aligning station has a horizontally arranged aligning table that supports the book in the spine region at least in the beginning and includes a forming rail that can be lowered on the fore edge cut of the book.
15. The binding-in machine according to claim 14, further including an infeed for the books and wherein the infeed takes place in the plane of the circulation path essentially transverse to the transport direction of the pressing devices and the infeed already takes place when the respective pressing device is still carrying out the forward movement to the feeding and aligning station.
16. The binding-in machine according claim 13, wherein there is at least one pressing station in which the pressing plates of the respective pressing devices are situated in the clamping position and subjected to a higher force of pressure by pressure means supported on the machine frame in order to press in a book situated between the pressing plates.
17. The binding-in machine according claim 13 wherein the delivery station provides for the gripped delivery of the formed and backed books, wherein the pressing device is controlled into the guiding position with minimally opened pressing plates and the books are pulled out of the respective pressing device by joint clamping rails that engage into the formed case joints.
18. The binding-in machine according to claim 17, wherein the joint clamping rails are situated on a pivoted arm that is moved along said circulation path and approaches the respective pressing device in the same transport direction and the pivoted arm is moved away from the pressing device in the opposite direction when the books are pulled out.
19. The binding-in machine according to claim 1 wherein two arrangements of rotating pressing devices are provided and arranged parallel to one another referred to their circulation path.
20. The binding-in machine according to claim 19, wherein the two arrangements are driven offset in phase by 180\xb0.
The claims below are in addition to those above.
