Abstract
An apparatus for operating the locks of wafer baking tongs, which revolve in a wafer baking oven and move past the stationary operating apparatus, which is mounted in the wafer baking oven, comprises a movable closing element, which is engageable with the actuating member of the lock to lock the latter. It is proposed to provide an unlocking element, which is engageable with the actuating member to unlock a lock which has not entirely been locked. An actuator is provided for moving the unlocking element into engagement with the actuating member when the closing element has been pushed back a predetermined distance from its operative position by the actuating member when the lock has not entirely been locked.
