SEMI-AUTOMATIC HANKING APPARATUS Abstract An apparatus for forming a length of elongate flexible material into a hank containing a selectable number of loops. The material is wrapped around a pair of post members which are mounted on a rotatable base member which in turn is drivingly connectable to a continuously-running electric motor via an electronically-controlled clutch and brake assembly. When the clutch is engaged the brake is released, thereby permitting the base member to be rotated by the motor, and when the clutch is released the brake is engaged, thereby accurately stopping the base member at a predetermined angular position. The electronic control circuitry activates the clutch and releases the brake when an operator depresses a foot switch, and releases the clutch and activates the brake upon receiving a predetermined number of signals representing revolutions of the rotating base member from a magnetic sensor positioned proximate the base member and responsive to the passage therepast of a ferrite element mounted on the base member. Operator-adjustable controls associated with the electronic control circuitry permit the base member to be stopped after any predetermined number of revolutions and at different predetermined angular positions. To facilitate the withdrawal of the finished hank after the base member has been stopped, the two posts around which the hank is wrapped are movable laterally toward each other, but are spring-biased to return to their respective outward-spaced position.
