Abstract

A method for production of adhesive-bound printed products in a machine belonging to an adhesive-binder line. To change over from one job under production to a following job, supplied printed products of the following job are detected via a barcode and stopped prior to being fed into the machine of the adhesive-binder line. Remaining printed products of a preceding job are moved and fully processed through individual processing stations of the machine while the printed products of the following job remain in a waiting position in front of the machine. After completing the last printed product of the preceding job, an empty withdrawal of covers stored in a cover deposit and belonging to the following job is initiated until it is ensured that the stored covers are available for the printed products of the following job. After determining that a withdrawn cover securely matches the printed products of the following job, stopped printed products of the following job are released with a main control and fed into the machine for being processed via the individual processing stations.

First claim

What is claimed is:

1. A method for producing adhesive-bound printed products in an adhesive-binder machine belonging to an adhesive-binder line, the an adhesive-binder machine having individual processing stations including a book spine processing station, an adhesive application station, and a pressing station with a cover that is withdrawn from a cover feeder, wherein the method for producing the adhesive-bound printed products is controlled by control profiles, the method comprising:
a) to changeover from one job under production to a following job, detecting supplied printed products of the following job via a barcode on the supplied printed products and stopping the following job prior to being fed into the machine of the adhesive-binder line;
b) moving and fully processing remaining printed products of the one job through the individual processing stations of the adhesive-binder machine while the printed products of the following job remain in a waiting position in front of the adhesive-binder machine;
c) after completing a last printed product of the one job, initiating an empty withdrawal of covers stored in a cover deposit and belonging to the following job until it is ensured that the stored covers are available for the printed products of the following job; and
d) after determining that a withdrawn cover securely matches the printed products of the following job, releasing, with a main control of the adhesive-binder line, stopped printed products of the following job, and feeding the released printed products into the adhesive-binder machine for being processed via the individual processing stations.

2. The method according to claim 1 , wherein before the releasing of the stopped printed products belonging to the following job, ensuring that at least one stored cover that matches the printed products is withdrawn empty.

3. The method according to claim 1 , wherein prior to releasing the stopped printed products for the following job, ensuring that the stored cover for the printed products of the following job is detected and is immediately available without empty withdrawal.

4. The method according to claim 1 , wherein prior to releasing the stopped printed products of the following job, ensuring that all excess covers belonging to the one job are withdrawn empty from the cover feeder until a matching cover for the printed products of the following job is detected.

5. The method according to claim 1 , wherein excess covers of the one job are withdrawn empty until the stored cover for the printed products of the following job is detected and is available without empty withdrawal.

6. The method according to claim 1 , further including converting the processing stations of the an adhesive-binder machine for producing the printed products of the following job by activating the control profiles for the following job before the stopped printed products belonging to the following job are released.

7. The method according to claim 1 , wherein the processing of any further job is based on the same processing steps as for the following job that initially follows the one job.

8. The method according to claim 1 , further including minimizing stopping times indicated by the stopped printed products for the following job by electronically detecting via barcodes a sequence of the stored covers and transmitting resulting information to a main control unit for the adhesive-binder machine to release the stopped printed products.

9. The method according to claim 8 , further comprising determining a sequence of the printed products fed into the adhesive-binder machine by a sequence of the available covers.

10. The method according to claim 1 , wherein with identically dimensioned printed products for different jobs which require different covers, no conversion takes place at the processing stations of the machine.

11. The method according to claim 1 , wherein if the original thickness of the printed product changes for different jobs, original settings for the processing stations of the an adhesive-binder machine remain unchanged up to a minimum range of +/−3.25 mm.

12. The method according to claim 11 , further comprising adapting at least one processing station of the adhesive-binder machine if the original product thickness changes for different jobs changes, exceeding the minimum range of +/−3.25 mm.

13. The method according to claim 11 , further comprising converting the processing stations of the adhesive-binder machine if the format, including one of width or height, of the printed product changes or if the thickness difference immediately exceeds the minimum range of +/−3.25 mm.

14. The method according to claim 1 , further comprising changing a geometric location for affixing grooves on the covers with a change in the book block thickness for the printed products.

15. The method according to claim 1 , wherein the cover is made of an inflexible material, and further comprising providing the cover with two folds separated by a book block thickness.

16. The method according to claim 1 , for a change in the dimensions of the printed products, the method further comprises, converting at least the processing stations of the adhesive-binder machine to measurements of the following job based on control profiles stored in a main control unit or which are computed, said converting taking place continuously at each processing station as soon as the last printed product of said one job has left a respective one of the processing stations.

17. The method according to claim 1 , further comprising:
controlling processes for producing the adhesive-bound printed products via control profiles;
scanning in externally ahead of time barcode information on covers belonging to printed products and electronically transmitting the barcode information obtained about the covers, including a sequence of the scanned covers, to a main control unit for the adhesive-binder machine and/or the other machines in the adhesive-binder line, wherein a sequence for printed products released for processing corresponds to the sequence of the scanned-in covers.

18. The method according to claim 1 , comprising the following machines and processing stations:
a collating machine for supplying printed products;
a machine with transfer elements located downstream of the collating machine for receiving and transferring the printed products;
an adhesive-binder machine arranged downstream of the transfer elements for receiving the printed products, the adhesive-binder machine including at least a book spine processing station, an adhesive application station, a cover feeding station, and a pressing station for adhesively binding a cover to a supplied printed product;
a discharge machine, which also functions as a cooling section arranged downstream of the adhesive-binder machine for receiving bound printed products from the adhesive-binder machine;
a three-way trimmer machine arranged downstream of the discharge machine for trimming the bound printed products;
a stacking machine arranged downstream of the three-way trimmer to stack the bound printed products; and
a book data acquisition device to input job orders based on different criteria to control the machines and stations of the adhesive-binder line.

19. The method according to claim 18 , comprising operating the individual stations of the adhesive-binder machine with a central drive shaft that extends through the complete adhesive-binder machine to form the drive of the individual processing stations of the adhesive-binder machi
