Abstract of the Disclosure A compact glue heater has two spaced apart metal plates welded together at their edges and a rib running part way along the center of the space to define a U-shaped conduit between the plates. A glue inlet pipe connects to one end of the conduit and an outlet pipe connects to the other. Electric heaters composed of heat resistant insulating sheets with electrically resistive material between them interface with the outside surfaces of the respective conduit forming plates. The heater and conduit assembly is sandwiched between metal plates which mount the assembly in a closed housing. A current controller, mounted within a partition of the housing, is governed by glue temperature and pressure sensors and a fusible element is provided for causing the controller to interrupt current to the heaters if an unsafe temperature is reached.
