摘要： Apparatus is illustrated for limiting the movement of tenter frame rails in order to avoid damage, particularly to chains, resulting from excessive movement which includes a spring biased plunger valve carried by the rail on one side of a rail junction, while the other side of the junction carries a member having a predetermined surface for actuating a switch when the member moves to an extreme position where it can no longer support the plunger against the resilient force of the spring, causing a switch to be activated to deactivate the motor imparting transverse movement to the rails.
