A hot gas generation device with which a gas flow, for example, an air flow, is heated. This device is used for heating an edge band or another coating material, in particular an adhesive layer provided on this coating material. In this way, the coating material is prepared for being applied to a (wooden) work piece, which may, for example, be plate-shaped.

A support for the heating elements of radiant coverings and floors includes bosses having a concave surface. In some examples, the concave surface includes at least one adhering low relief that creates an extraction-preventing undercut on the concave surface.

A temperature regulation unit includes a housing, a conduit, a fan, and a thermal element. The housing has a sidewall with an upper end and a lower end. The sidewall defines an internal cavity. The conduit is disposed within the internal cavity of the housing and defines a passage. The conduit has a first end and an opposing second end. The fan is positioned within the internal cavity of the housing at the first end of the conduit. The fan is configured to provide an airflow to the passage of the conduit. The thermal element is positioned within the passage of the conduit. The thermal element is configured to thermally regulate a temperature of the airflow flowing past the thermal element and out of the opposing second end of the conduit.

A heat-shrinkable tube heating apparatus of the present invention comprises a pair of heat source boxes that are configured to be plane-symmetrical to each other. A blower pipe and a pair of heating tubes are disposed parallel to each other inside each of the pair of heat source boxes wherein air jet holes are formed side by side on the blower pipe. The pair of heating tubes, each including a heating wire emitting infrared rays, are arranged across an open area on one side of each heat source box, the blower pipe is disposed between the pair of heating tubes to be positioned more inside than the pair of heating tubes from the open area, and the blower pipe is installed so that a pressurized air flowing thereinto is blown out through the air jet holes toward one of both sides of heat-shrinkable tubes placed for being heated.

A radiation heating device includes: a planar heat generation layer; a heat generation portion that is provided in the heat generation layer and that generates heat by energization; a plurality of heat radiation portions that are disposed in the heat generation layer and that radiate heat transferred from the heat generation portion; a low heat conduction portion that is provided around each of the heat radiation portions and that has a lower heat conductivity than the heat radiation portions; and a contact detection unit that detects contact of an object with the heat generation layer. The radiation heating device further includes an energization amount decrease unit that decreases an energization amount of the heat generation portion when the contact detection unit detects the contact of the object with the heat generation layer.
