Abstract: An assembly which is a composite including an end shield and a front wall. The size and shape of the end shield are adapted to the inner face of the front wall. Both parts are dimensioned and formed in such a way that they can be interconnected in a fixed manner to form a stable composite resembling a sandwich assembly. The joint surfaces between the front wall and the end shield lie on perpendicular planes and extend for some distance. The construction and connection of the individual parts and of the composite give the front region of the tumble dryer a high degree of rigidity, which obviates the need for additional reinforcement measures. The assembly thus saves material and mounting costs and resources.

Abstract: A method carried out without sealing elements inside fixed parts in the front area of a condensation dryer. A process air channel arranged in a shield is made of a plastic material and is provided with a vertical dividing surface which is placed at the level of a heat exchanger reception area in front of a base module. Said base module and the shield are assembled without additional sealing means. The tightness of the process air guide along the passage from the shield to a condenser is obtainable by supporting surfaces devoid of welds and hitches on the edges of the heat exchanger insertion opening, sealing elements placed on the circumference of a heat exchanger are pressed to each other when the dryer is prepared to operate.
