METHOD FOR CONTROLLING AND RECORDING TECHNOLOGICAL PARAMETERS OF PAPER FLAT OF INPUT ROLL ON PRINTING FACTORY AND SYSTEM FOR REALIZATION OF SAID METHOD Russian patent published in 2008 - IPC B41F33/02 D21G9/00 

FIELD: polygraphic industry, possible use for controlling technological parameters of paper flat of input roll on printing factories, which is formed in advance at paper factory.

SUBSTANCE: in the method, length of flat part of input roll, which includes control marks, is selected as controlled parameter. Marks are positioned with constant value step, which is selected depending on technologically acceptable error relatively to length of roll flat, regulated by its tensioning during technological cycle of creation of this roll at paper factory. Detection, recognition and registration of informative signs of controlled parameter is performed twice. Namely: during insertion of a roll into technological zone of roll printing machine and during removal from it. Recording of read and transformed information in memory block of electronic computing device is performed with ensured storage of that information and its possible output to information carriers, which are functionally a "roll report" with given database, based on "roll passport" information. Particularities of the system are as follows. It is provided with second block of optic-electronic devices, functionally and structurally identical to first block. One block is mounted at the point of insertion of a flat into technological zone of roll printing machine, second one - at exit point of same. Each block has commutated connection to its own electronic computing device. In front of each block, flat speed sensor is mounted, in commutated connection with corresponding electronic computing device. Software of one of the blocks is created with possible creation of database of input roll flat, and of another block - of output roll flat, and with possible storage of that information in memory blocks and its output to information carriers, which functionally act as "roll reports".

EFFECT: possible control of technological parameters of flat at input and output of roll printing machine, resulting in increased precision of control.
