ABSTRACT:
In a device ensuring safety and protection around the unit by which a cigarette rod is dried and sealed in cigarette manufacturing machinery, a hinged guard is positioned alongside the area of the machine where the heat plate of the drying and sealing unit moves and operates; the guard is capable of movement between a shut position denying access to the operating area and a position whereby access is afforded to the area. A microswitch senses when the guard is in the shut position, denying access to the operating area, and relays an enabling signal to the control valve piloting the cylinder by which the heat plate is lowered, only when the guard is in this same safe position.
