ABSTRACT:
Process of register adjustment or maintenance by means of register marks and an index pulse of the processing element, in which a position pulse train indicates the instantaneous position and the speed of the processing element during each of its cycles. It is essentially characterized in that, to allow an automatic initial register adjustment and maintenance, it consists in determining and storing, in the form of numerical sequence, at least one characteristic of a selected register mark, in continuously picking up the signal of a detector, in sampling this signal synchronously from the position pulses, between the index pulses, and in writing the results in memory, in the form of numerical values, at successive addresses, in periodically analyzing the memory contents to locate in it the sequence of numerical values corresponding best to that determined as a function of the selected register mark in calculating, from a specific address of said sequence, and from the position of the processing element associated with it, the deviation between the actual position and the set point of the register mark and, from the deviation thus calculated, in applying the desired correction to bring the deviation to zero. The invention is particularly useful in off-line machines processing a web of preprinted material.
