  • Publication number: 20160257157
    Abstract: The present invention discloses a method and apparatus for an automatic variable creasing with a digital creaser. This method includes the following steps: determining a zero point position C0, a starting location C1, and a variable parameter X; transferring a paper sheet i to the creasing area of an creaser, and calculating creasing position P of the paper sheet according to the zero point position C0, the starting location C1, the variable parameter X and i, making an crease at the creasing position P. This apparatus is composed of a parameter obtaining module, a detection module, a transferring module, an creasing module, and a processing & control module. The present invention realizes the object of automatic variable creasing, making the variable creasing efficiency higher, the precision higher, facilitating binding and page turning of thick paper books.
