Abstract: A safety shut off mechanism for a sealing machine includes a housing having a front board, and a door panel rotatably secured to the front board and rotatable between an outward position, an inner position, and an intermediate position. A switch member may be attached to either the board or the door panel and may be actuated when the door panel is disengaged from the intermediate position or moved inward or outward toward the outward position or the inner position, so as to shut off the sealing machine when the door panel is not in the intermediate position.
