PURPOSE:To permit an arbitray-pitch sheet to be manufactured by transmitting a pulse signal pey each specified revolution angle of a drum and also per each revolution of said drum, and thus transferring a guide to a predetermined position and placing marks on a filament-shaped material. CONSTITUTION:As for the revolution angle of a drum 1, a pulse signal is output per each specified revolution angle of the drum from a rotary encoder 3 and input into an arithmetic circuit 4. In the arithmetic circuit 4, the input pulse signal is divided with a prescribed ratio, a motor 5 is driven by this pulse, and the position of a guide 7 is controlled by a screw 6. At the same time, the rotary encoder 3 permits output of pulse per each specified revolution number of the drum, said pulse is also input into the arithmetic circuit 4, and a pulse is output per each prescribed revolution number. A mark having a certain length is formed on a filament-shaped material every specific number of filament by driving a solenoid 8. |
