Devices for dewatering washed laundry have a pressing membrane. The pressing membrane is releasably fastened below a ram plate of the device by way of a fastening ring. This connection is very complex by virtue of the heavy weight of the pressing membrane which has a diameter of approximately 1 m. In order for the fastening of the pressing membrane by way of the fastening ring below the ram plate to be facilitated, it is provided that the pressing membrane on the membrane collar thereof has at least one internal-side protrusion which while assembling the pressing membrane below the ram plate forms a bearing for the fastening ring. On account thereof, the fastening ring is temporarily supported below the ram plate while assembling the pressing membrane, this permitting easier assembling of the pressing membrane below the ram plate.
A pressing membrane (19) for a device for dewatering laundry (10), having a membrane base (27) and a membrane collar (28) which is molded on the membrane base (27) and has an encircling upper periphery (29) and a peripheral region (30) which for releasably fastening the membrane collar (28) by means of a fastening ring (32) below a ram plate (18) of a press ram (17) emanates from said upper periphery (29), said ram plate (18) being able to be moved up and down, wherein the membrane collar (28) on an internal side thereof has at least one protrusion (36) for forming an at least temporary bearing for the fastening ring (32) until connecting the pressing membrane (19) to the ram plate (18) wherein the at least one protrusion (36) of the membrane collar (28) forms an upper bearing face (37) for the fastening ring (32), wherein the respective bearing face (37) of the at least one protrusion (36) lies in a plane which orthogonally intersects the longitudinal central axis (33) of the pressing membrane (19) and the membrane collar (28) thereof.
A device for dewatering laundry (10), having a press ram (17) which has a ram plate (18) and a flexible pressing membrane (19) that is releasably fastenable below said ram plate (18) by way of a fastening ring (32), said press ram (17) being able to be moved up and down, and the pressing membrane (19) having a membrane base (27) and a membrane collar (28) which is molded on the membrane base (27) and has an encircling upper periphery (29), wherein the membrane collar (28) on an internal side thereof has at least one protrusion (36) which is configured as a bearing for the fastening ring (32) at least until connecting said fastening ring (32) to the ram plate (18) wherein the at least one protrusion (36) forms a bearing for the fastening ring (32) at least until connecting the fastening ring (32) to a lower side of the ram plate (18).
