Abstract

A method for creating a fold preparation pattern includes supplying job-specific signature characteristics to a computer and determining job-specific cutting requirements by using general cutting requirements assigned to respective general signature characteristics in the computer and using the job-specific signature characteristics. The computer accesses a database that contains cutting, trimming, and clipping patterns and compiles job-specific fold preparation patterns in accordance with the job-specific cutting requirements. A computer for implementing the method and a system having the computer are also provided.

First claim

The invention claimed is:

1. A method for creating a digital fold preparation pattern, the method comprising the following steps:
assigning at least one of cutting, trimming or clipping patterns in accurate positions to a plurality of paper sheet signatures defining a thickness of a product, by:
supplying job-specific paper sheet signature characteristics to a computer, including at least grammage and fold pattern of the paper sheet signature;
determining job-specific cutting requirements using general cutting requirements assigned to respective general paper sheet signature characteristics in the computer and using the job-specific paper sheet signature characteristics; and
using the computer to access a database containing cutting, trimming and clipping patterns and compile a job-specific digital fold preparation pattern from the cutting, trimming and clipping patterns in accordance with the job-specific cutting requirements for supplying the digital fold preparation pattern to a fold preparation device to prepare a paper sheet signature for folding the plurality of paper sheet signatures defining the thickness of the product in a folding machine.

2. The method for creating a fold preparation pattern according to claim 1 , wherein at least one of the cutting patterns or trimming patterns include cutting lines, crease lines and perforation lines.

3. The method for creating a fold preparation pattern according to claim 2 , which further comprises forming a perforation line of a plurality of perforation points having a position on the perforation line being unevenly distributed using an algorithm.

4. The method for creating a fold preparation pattern according to claim 1 , wherein the clipping patterns include at least one of circles, ovals, polygons or crosses.

5. The method for creating a fold preparation pattern according to claim 1 , wherein the job-specific signature characteristics further include at least one of type of stock, format, target format, partition or thickness.

6. The method for creating a fold preparation pattern according to claim 1 , which further comprises modifying the fold preparation pattern with inputs into an interface connected to the computer.

7. The method for creating a fold preparation pattern according to claim 1 , which further comprises supplying the fold preparation pattern to a fold preparation device.

8. The method for creating a fold preparation pattern according to claim 1 , which further comprises supplying the fold preparation pattern to a fold preparation device and storing the fold preparation pattern for repeat orders.

9. The method for creating a fold preparation pattern according to claim 1 , which further comprises storing the fold preparation pattern for repeat orders.

10. A computer implementing the method for creating a fold preparation pattern according to claim 1 .

11. The method for creating a fold preparation pattern according to claim 1 , which further comprises enabling a machine operator to make any necessary corrections to the fold preparation pattern in a separate step.

12. A system, comprising:
a computer implementing the method for creating a fold preparation pattern according to claim 1 ;
a folding machine for folding the plurality of paper sheet signatures defining the thickness of the product, the folding machine having a control unit, positionable guide elements and stops for guiding sheets;
a data link interconnecting said computer and said control unit; and
said control unit communicating position changes of said guide elements and said stops to said computer for adapting the fold preparation pattern.
