Abstract

In a double band press the compressing pressure is applied to the endless bands by pressure plates via intermediate pressure rolls. The pressure rolls extend transversely to the running direction of the steel bands and are interconnected at their ends by a guide chain. More than two pressure rolls are associated with each pair of connecting bolts of the guide chain. The axes of the pressure rolls are parallel and are offset transversely relative to the axes of the connecting bolts of the guide chain. In this manner, a stable connection of the pressure rolls among themselves is made possible, with the pressure rolls having a smaller diameter and being capable of being arranged closely adjacent to each other. A more uniform and higher distribution of pressure may be obtained thereby.
