Heating apparatus having multiple heating chambers movable between a first position with opposed open sides and a second position with opposed open sides

摘要

Described is a heating apparatus which in case of need guarantees nonproblematic access to the objects to be heated, without incurring heat losses. Used in conjunction with lip rolling apparatuses, the heating apparatus features at least two movably arranged heating boxes (1) and (2) , which via parallelogram linkages connected in swingable fashion to a stationary support element (13), such that in their inoperative position they are away from the object to be heated and have assumed closed position as well.
