Abstract
In a continuous twin-belt prepress for the production of particle board panels with pressure rollers suspended in pairs, the upper pressure rollers are suspended resiliently so that they can be pressed upwardly counter to the spring force by a catch member of a metal support screen bearing the chipboard cake when that member passes through. This prevents damage to the press and especially its forming belts as a result of increased pressure during pressing.
