ABSTRACT:
The press contains a platen and a ram adjustably mounted with respect to the platen to define a press gap for receiving material. A first conveyor band is disposed around the platen and a second conveyor band is disposed around the ram. A plurality of rolls for supporting and guiding the first and second bands are mounted to the platen and ram, respectively. Countersupports are provided for the rolls. The countersupports comprise a plurality of change plates, each of which is capable of being mounted to and removed from a platen or ram. Each change plate includes a first rod mounted in a first level and connected in supporting relation with one of the rolls. A plurality of T-shaped web plates are connected to the first rod in the first level and to a pressure plate in a second level whereby counter-pressure from the material being pressed is transferred to the pressure plate.
