Abstract
A method of manufacturing a waterproof heating mat includes pouring a first amount of a liquid polymer onto a surface of a conveyer belt; partially curing the first amount of liquid polymer to form a first layer; placing a heating film on the first layer such that at least one side of the heating film is covered by the first layer; pouring a second amount of the liquid polymer onto the heating element and the first layer; and curing the second amount of liquid polymer to form a second layer, the second layer contacting the first layer to at least partially encapsulate the heating element between the first layer and the second layer.
Claims25
A method of manufacturing a waterproof heating mat, the method comprising:
- dispensing a first amount of a liquid polymer onto a surface of a conveyer belt;
- partially curing the first amount of liquid polymer to form a first layer;
- placing a heating film on the first layer such that at least one side of the heating film is covered by the first layer;
- dispensing a second amount of the liquid polymer onto the heating element and the first layer;
- and
- curing the second amount of liquid polymer to form a second layer, the second layer contacting the first layer to at least partially encapsulate the heating element between the first layer and the second layer.
A method of manufacturing a waterproof heating mat, the method comprising:
- dispensing a first layer of liquid vinyl on a first end of a moving conveyer belt such that the first layer at least partially cures between the first end and a second end;
- placing a heating film on the first layer while the first layer is curing;
- dispensing a second layer of liquid vinyl onto the conveyer belt;
- partially curing the second layer on the moving conveyer belt between the first end and the second;
- and
- placing the heating film in the curing second layer to at least partially encapsulate the heating film within the first and second layers.
A waterproof heating mat comprising:
- a base layer of solidified vinyl;
- a top layer of solidified vinyl, the top layer positioned over and adhered to the base layer to form an open pocket defined by a periphery of the base layer;
- and
- a heating film, the heating film positionable within the pocket and adhered to the base layer and the top layer.
