Abstract
A press for producing continuous sheets, for example, that which is fabricated into circuit boards for printed electrical circuits. There are two endless steel belts, each of which is mounted on a pair of drums or rolls which support the belts so that there are coextensive belt runs which define a treatment zone in which the product is formed. The coextensive belt runs are held in precisely spaced relationship by a pair of pressure plates which may also act as heating plates. Each of the pressure plates is supported from the press structural members by a plurality of support strips which are positioned in rows longitudinally of the treatment zone. The strips of one of those rows adjacent each of the longitudinal side edges of the treatment zone are wedge units. Each wedge unit is adjustable to flex the edge of the support plate and change the thickness of the press-gap in that area. In that way, it is possible to produce a product having precisely controlled uniform thickness throughout.
