Abstract
A machine for wrapping articles uses several guard covers to enclose its operating mechanism for safety purposes. A switch in the machine must be actuated to enable machine operation. At least one cover is provided with a switch actuator and one or more other covers have interlocks which must be properly set by having all covers in place to permit the actuator to actuate the switch.
