Abstract

PURPOSE:To enable a pattern of desired size to be printed simply and in a short time by a method wherein tension is detected near a printing cylinder and a desired value of tension for the purpose of tension control is given as a value calculated from the thickness and the width of a blank. CONSTITUTION:A pair of infeed rollers 3 and a pair of printing cylinder 4 are driven by the rotation of a motor 5 to print the blank 2. The change of tension of the blank 2 is converted into an electrical signal Tp by a tension gage 7 through a detecting roller 6, supplied to a comparison computing circuit 8, a deviation signal DELTAT between the signal Tp and a tension value computed T is taken out, given as a control signal to a paper-feed brake 10 through an amplifier 9 and operates the blank 2 so that its tension can hold a desired value. Since the detecting roller 6 and the tension gage 7 are provided between the infeed roller 3 and the printing cylinder 4, the signal Tp reflects the correct tension just before the signal is supplied into the printing cylinder 4 and the printed pattern and size can be held easily within the desired accuracy.
