Abstract

The metal object carries a layer of heat activated adhesive. The core is U-shaped and laminated, and has flat surfaces at the end of each leg, which can be joined with surfaces of the metal object to be heated. The flat joining surfaces (18) carry insulating separators (28, 29), which project slightly above the surfaces. They are used to determine an exactly defined, specified narrow gap between the end surfaces and the adjacent metal object (34), when the separators firmly rest on the object surface.
