METHOD OF MARKING AND CONTROL OVER THE TECHNOLOGICAL PARAMETER OF THE PAPER SHEET STRIP OF THE OUTPUT PAPER ROLL AND THE SYSTEM FOR THE METHOD REALIZATION Russian patent published in 2008 - IPC B41F5/04 G01N21/91 

FIELD: printing industry; other industries; method and the device used for marking and control of the technological parameter of the paper sheet strip of the output paper roll.

SUBSTANCE: the invention is pertaining to the field of printing industry and may be used for control over the length of the paper sheet strip of the output paper roll. The special feature of the method of the marking and control over the technological parameter of the paper sheet strip of the output paper roll is that in the capacity of the controlled parameter select the length of the paper sheet strip(1) of the output paper roll (2). In the capacity of the control marks (3) use the digital code with the element indicating the direction of reading-out. The spacing (4) between the control marks (3) take of the preset value. The received data are stored in the memory unit of the computer (8). The special feature of the system used for marking and control over the technological parameter of the paper sheet strip of the output roll is that it additionally contains in series located between the marking tool (10) and the unit of the optical-electronic devices of the control and registration(5) there is the speed sensor (11) and the cutting apparatus (13). The speed sensor (11) and the marking tools are switch-connected with the computer (8). The software the computer (8) is formed with the capability of application by tools of marking (10) of the control marks (3) by the method of printing on the field of the paper sheet strip (1) along the whole length of the roll (2) with the spacing (4) of the preset value, registration of the spacing value (4) between the control marks (3), memorizing of the observed and transformed readings in the memory unit of the computer (8) with provision of saving of the information and the capability of its delivery to the appropriate information carriers. The invention ensures the increased accuracy of the control over the paper sheet strip length.

EFFECT: the invention ensures the increased accuracy of the control over the paper sheet strip length.
