摘要：
The invention refers to a device for dewatering and/or washing suspensions, especially fibre stock suspensions, with two dewatering rolls rotating in opposite directions, where at least a further two guide rolls, especially press rolls, are provided and a woven, especially endless woven, wire or filter belt runs over each combination of one dewatering roll and one further guide roll, by which arrangement the suspension to be dewatered and/or washed is carried in the gap between the two belts and dewatered. The invention is mainly characterised by the two belts forming a vertical gap and by a device to guide the belts being mounted in the region of this vertical gap.
