ABSTRACT:
A machine draws stock from a source to a first work station at which a first operation is performed on the stock. The stock is then delivered to a second work station so a second operation may be performed on the stock. The machine has an electromechanical system which drives the machine and a switch energizes and deenergizes the system. The stock is engaged by a lever arm as it moves toward the first work station, the lever arm being held in a first position when engaging the stock and moving from the first position toward a second position when the end of the stock is reached. A contact bar moves the switch from its "on" to its "off" position to deactivate the electromechanical system and terminate the drawing of stock. The lever arm and the contact bar are interconnected so movement of the lever arm from its first position to its second position is transmitted to the contact bar. The contact bar moves the switch to its "off" position in response to the movement of the lever arm whereby the electromechanical system is deactivated and the drawing of stock terminated.
