Abstract
A drive circuit for setter rollers is automatically coordinated with a spool drive to insure a condition of tension in a longline at all times during the setting operation. The apparatus includes various rollers to achieve the method, and in addition, circuits for controlling the motor adapted to drive the speed rollers at different but correlated rates of speed. While the fluidic circuit is hydraulic, alternative electronic controls may be employed.
