Replacement cassette mechanism for metal belts in twin-belt press for the resin impregnation of decor paper

摘要

A twin-belt press (A) has an upper metal belt (5) running around an upper pair of rollers (3, 3) and a lower metal belt running around a lower pair of rollers (4, 4). One side of the press is held free for the replacement of metal belts as necessary. The exchange is effected by two magazines, each with a metal belt cassette whose dimensions are identical with those of the press. An empty magazine receives the expired belts and a further magazine inserts replacements. The belt exchange mechanism is an integral part of the magazine.
