Abstract
PURPOSE: To prevent the slackening of paper by supplying the tension correcting signal corresponding to the slack amount of a paper at the moment when tension varies.
CONSTITUTION: When slack is generated on a paper, the output signal of a tension detector 9 reduces sharply in zero direction, and a differentiation circuit 14 generates the output corresponding to the sharp variation amount. A contact 15 is closed simultaneously with the injection of application liquid, and the output of the differentiation circuit 14 becomes the input of an amplifier 12, and increases the speed of a dryer motor 6 through a thyristor power source 13. Thus, the slack of paper decreases, and the output signal of the tension detector 9 increases from zero direction, and the deviation between the signal of the tension detector 9 and the tension standard signal of a tension setting resistor 10 is amplified in an amplifier 11, but as the response is slow, the tension correcting signal due to the rapid response of the differentiation circuit 14 is applied. After the slack of the paper is absorbed and the variation of tension is stabilized through tension control due to the amplifier 11, the contact 15 is opened after the lapse of a fixed time.
