A device for melting low temperature glue or hot-melt glue and for maintaining the melted glue at a substantially uniform temperature throughout a container and for applying a coating of substantially uniform thickness of such glue to articles, and edge of sheets to form books or tablets, one side of the elongated strip of material to form tape, and the like includes a pre-melting chamber for melting glue such as low temperature or animal glue, hot-melt glue or glue at temperatures therebetween and communicating with said container. The applying device having an inner chamber with walls spaced from walls of an outer housing and having temperature insulating material filling the space therebetween. Heating units are in the walls of the inner housing and in ribs therefrom to maintain the glue within the inner housing at a substantially uniform temperature throughout the inner housing. Rollers are rotatably mounted on one of the outer housing and the inner housing and have means movable through the glue within the inner housing to apply a coating thereof to material moved into engagement with the peripheral edges.
