Abstract
The invention relates to a roller belt drier. The drying of panel-shaped products often requires the drier to have considerable construction lengths in order to achieve a high capacity. Long roller belt dryers, which are usually equipped with chain drives and a motor for each chain, present the problem that very strong chains are required to transmit the necessary driving forces. When the drier reaches a certain length, it is no longer possible to provide chains that are able to accommodate these forces. According to known solutions, a chain is divided and the drives are located in the centre of the drier. This causes problem s in terms of sealing the drier, as well as extra expense for the driving and tension station. The aim of the invention is to create a drier which has a driving and tension system that is structurally simple and economical even for considerable construction lengths. A chain is equipped with two drives (15, 23), the second drive (23) being integrated in a tension device (24). The invention is suitable for drying panel-shaped goods, especially plaster boards or plaster fibre boards.
