FIELD: process engineering.
SUBSTANCE: invention relates to pressure-equalising cushions for hydraulic hot-pressing plants. Proposed cushion is made from pressure-equalising fabric. Said fabric comprises metal threads making fabric warp threads, filler threads and elastomer heat-resistant threads. The latter incorporate, preferably, stabilising rod threads and are arranged either as warp or filler threads alternating with metal threads. Cushion thickness in non-compressed state is subject to elastomer threads. At moderate pressure, sections of contact with hydraulic plant parts are formed at the start of elastomer threads. The latter are compressed to form additional sections of contact with hydraulic plant parts are formed at the start of elastomer threads in further increase of pressure to full operating pressure.
EFFECT: increased quality of final products.
