Abstract
A magnetic separator for separating magnetically permeable, stacked sheets has permanent magnets mounted on a movable support for movements toward and away from the stack of sheets. The magnets normally occupy a position closely adjacent the stack of sheets but are movable away from such position in response to inflation of inflatable and deflatable air bag activators. Deflation of the air bag actuators enables biasing springs to return the magnets to the normal position. The rate of inflation and deflation of the actuators is controllable so as to regulate the rate of movement of the magnets.
