Abstract
In order to avoid undesirable delays in response time for controlling feed roll directional rotation and stopping, an electric clutch-brake planetary gear device provides stop, forward and reverse control of the feed rolls. The device functions as an electric clutch for a forward mode and as an electric brake for a reverse mode. Almost instantaneous shut down is available which is desirable for use in combination with a metal detector.
