Press cushion for a hydraulic press
摘要:
A press cushion (7, 17, 27) for a hydraulic press (1) including a first layer (9, 19, 39) which is impermeable to fluids and includes an elastomeric material and fibers connected therewith; a second layer (10, 20, 40) connected with the first layer (9, 19, 39), wherein the second layer is also impermeable to fluids, wherein the first layer (9, 19, 39) is provided with a plurality of channels (15, 22, 28, 36) on its side oriented towards the second layer (10, 20, 40), wherein the channels include a material that is flow-capable at least at the operating temperature of the press (1). Additionally the channels (15) are closed fluid tight at least through the second layer (10, 20, 40).
