ABSTRACT:
A continuously operating panel press having a series of separately adjustable heater pads and two pairs of likewise adjustable pressure rollers with intermediate pressure pads, the pressures being adjusted for a progressively decreasing pressure pattern along the work gap, a first zone being adjusted for high pressure while successive zones exert less pressure against the press work, as it is pulled through the press by means of endless band conveyors. When excessive resistance is encountered, the highest pressure is alternatingly shifted from rollers to pads and vice versa, while the other pressures are briefly relaxed.
