PURPOSE:To obtain this device that consists of a printing roll for printing marks to a travelling filament body, a means for flickering irradiating marks while synchronizing with the revolution of the printing roll and a means for revolution controlling a mark location detector and the printing roll and prints distinct marks to the filament body. CONSTITUTION:A control roll 6 for marking to this filament body 1 is rotation driven by means of a drive motor 3 speed controlled by supplying it with output signals, which are proportional to the travelling speed of the filament body 1 from a speed detecting roll 2 for detecting the travelling speed of the filament body 1, through a tuning ratio set instrument 4 and an amplifier 5, an oscillator 8 generates pulse signals by means of a projection 7 mounted to the control roll and a stroboscope 10 for irradiating the filament body 1 is flickered. A location of an image of a printing mark is detected by means of a printing mark location detector 11, the turning ratio set instrument 4 is adjusted by the output and the travelling speed of the filament body 1 and the rotary circumferential speed of the printing roll 6 are accorded. |
