This prepressing machine is also called cold press, which has a large daylight. A pack of spread veneers, ususally enough for two or three hot press loads, is placed under pressure at normal atmospheric conditions.The aims are to transfer glue from the spread to the unspread surface of the veneer to obtian a better glue bond and to develop some strength in individual panels.
