Abstract

The process is used to apply a thermohardening lining to one side only of a chipboard panel. The operation is carried out in a single or multi-stage bed press using heated platens. These are first heated to give a preset difference in temperature between their pressure faces, this difference being 10-25 deg.C per millimetre of panel thickness. The lining comprises a paper impregnated with the thermo-hardening resin and this is applied to the hotter of the two faces. The difference in temperature compensates for the bowing effect of the lining.
