The advantageous effects of the present invention are as follows. The present invention adopts the method for automatic variable creasing with a digital creaser. Before creasing, positions of individual paper sheets and variable parameters are determined; creases are made before the creasing positions of individual paper sheet are determined. The subsequent paper sheet creasing position then changes with the influence of the variable parameter X. With the unremitting work of the creaser, multi paper sheets with different creasing positions are printed out successively. Therefore, the purpose of automatic variable creasing is realised, making the variable creasing efficiency and precision higher, and facilitating the book binding and page turning of thick paper books. The apparatus of the present invention for automatic variable creasing with a digital creaser is specially designed for the said method for automatic variable creasing. The present invention can be used in book creasing.
A detailed description of the embodiments of the present invention is made below in combination with the attached drawings.
It should be noted that the embodiments in this application and the characteristics of the embodiments can be combined without conflict.

Step 1 includes determining a zero point position C0, a starting location C1, and a variable parameter X, wherein parameters C0, C1 and X are all numerical values. C0 and C1 correspond to the position of paper sheets in the creasing areas. For example, when the zero point position of a paper sheet is arranged at the head end, then C0 equals 0; when zero point position is set a certain distance off the head end, then C0 is larger than 0. Parameter C1 is used to determine the creasing position P of the first paper sheet entering the digital creaser. The parameter C1 may be any real number, for example, when the creasing position P of the first paper sheet coincides with zero point position, then C1 equals 0. In the step S1, the zero point position C0, the starting location C1 and the variable parameter X may be set by default, or set through entering parameters into the computer system of the digital creaser by a user every time. The variable parameter X may be any real number (including positive numbers and negative numbers).
Step 2 includes transferring a paper sheet (i) to the creasing area of the creaser, and calculating paper sheet creasing position P according to the zero point position C0, the starting location C1, the variable parameter X and (i), making a crease at the creasing position P, wherein the introduction of the variable X enables that different papers may have different creasing positions. The value of the variable parameter X is determined according to the thickness of a paper sheet. The algorithmic method of creasing position P is set as required, for instance, by arithmetic progressive increase, isometric progressive increase, arithmetic degression, and the like.

The method for automatic variable creasing with a digital creaser according to the first embodiment of the present invention, uses, in said Step S2, the following formula for computing the creasing position: P=C0+C1+(i−1)*X. The creasing positions P of individual paper sheets form an arithmetic increasing/decreasing sequence. When X is a positive number, the method is implemented and the schematic diagram of the bound book paper sheets is shown in
Determining the total number N of paper sheets can also be included in Step S1. The total number of paper sheets can either be set by default, or set by a user at each time through entering parameters into the computer system of the digital creaser. Generally, the total sheet number N equals to the number of pages in a book. In case of batch creasing, when the sequence number of paper sheets transferred is larger than N, (i) can be reset as 1, namely, continuous variable creasing for mass production of multiple hooks is realized.
