Abstract

Ein Presspolster (7) für eine hydraulische Presse (1) weist eine erste für Fluide undurchlässige Schicht (9) auf, die elastomeres Material und damit verbunden Fasern aufweist. Das Presspolster (7) weist darüber hinaus eine mit der ersten Schicht (9) verbundene zweiten Schicht (10) auf, die ebenfalls für Fluide undurchlässig ist. Um ein auf einfache Weise herstellbares Presspolster (7) zu erhalten, bei dem sich die Elastizität in eine Richtung quer zu der Polsterebene bereichsweise unterschiedlich einstellen lässt, wird vorgeschlagen, dass die erste Schicht (9) auf ihrer der zweiten Schicht (10) zugewandten Seite mit einer Mehrzahl von Kanälen (15) versehen ist, in denen sich ein zumindest bei Betriebstemperatur der Presse fließfähiges Material befindet. Darüber hinaus sind die Kanäle (15) zumindest durch die zweite Schicht (10) fluiddicht verschlossen.

A press pad (7) for a hydraulic press (1) has a first fluid impermeable layer (9) comprising elastomeric material and fibers connected thereto. The press pad (7) also has a second layer (10) connected to the first layer (9) which is also impermeable to fluids. In order to obtain a press pad (7) which can be produced in a simple manner, in which the elasticity can be adjusted in different directions in a direction transverse to the cushion plane, it is proposed that the first layer (9) face on its side facing the second layer (10) is provided with a plurality of channels (15) in which there is a flowable material at least at the operating temperature of the press. In addition, the channels (15) are at least fluid-tightly sealed by the second layer (10).
