ABSTRACT:
Phase control device comprising a driven wheel and a driving wheel. The driven wheel engages an endless loop, whose going part toward the driving wheel and returning part from the driving wheel engage a pair of idling wheels and one or plural pairs of movable wheels. The movable wheels are finely adjusted toward a cross direction to the endless loop so that either the going part and the returning part is pulled, while the other is slackened. As a result, the phase of the driven wheel is changed so that timing of the driven wheel against the driving wheel can be regulated. The phase control device provides timing of the operation of a pair of machines such as coveyors which link mutually.
