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.
Claims18
A method of continuously pressing a material particle mat in which material particles are spread on a flexible support screen comprising:
- continuously drawing the screen with the mat upon it into a press having at least one resiliently spring mounted pressure roller to compress the mat, by means engaging a catch member of said screen;
- and allowing the roller to move counter to the spring force transversely to the plane of the mat upon contact of foreign bodies, said foreign bodies including said catch member, conveyed along with the mat and passing through the press with the pressure roller.
A twin-belt press for continuous compression of a material particle mat deposited on a support screen comprising two forming belts running endlessly around guide drums between which a pressing segment is formed for compressing the mat continuously conveyed through the press on said support screen, and at least one pressure roller arranged on the pressing segment and forming a gap with an opposing counter-pressure roller in which the mat is compressed as it passes therethrough, said pressure roller being resiliently mounted by a spring and adapted to be moved away from the mat counter to the spring force by foreign bodies conveyed along with the mat, said foreign bodies including a catch member of the support screen.
