Abstract
Herein disclosed is a web paper cutting position adjusting system which comprises: marking means including a control unit for generating a predetermined phase detection signal by detecting a predetermined rotational phase of a platen, and a marking unit for marking a web paper in response to the predetermined phase detection signal; web paper cutting means disposed a predetermined distance downstream of the marking means for cutting the web paper; mark detecting means interposed between the marking means and the web paper cutting means for detecting the mark to transmit a mark detection signal; cutting phase signal transmitting means associated with the operation of the web paper cutting means for transmitting a cutting phase signal; and web paper threading path changing means including an arithmetic unit having an operation signal transmitting unit made receptive of the mark detection signal and the cutting phase signal for transmiting a web paper threading path length changing signal, if the transmission timing of the mark detection signal is outside of a predetermined range for allowance of the cutting phase signal, and a web paper threading path length changing unit disposed upstream of the mark detecting means for changing the threading path length of the web paper in response to the web paper threading path length changing signal.
