CONTINUOUS PRODUCTION OF PARTICLE BOARD HAVING APPLIED SURFACING

摘要

A laminar board having a base of bonded wood particles carrying a decorative facing is produced by sequentially moving a carrier web through a loading zone and a press zone. The carrier web consists essentially of paper impregnated with a synthetic resin composition and having a permeability to water vapor of at least 1000 g/m2/day. A layer of loose wood particles intimately mixed with a bonding agent is superimposed on the carrier web in the loading zone, and the resulting layered material is subjected in the press zone to a temperature and pressure sufficient to bond the loose particles to each other by the bonding agent in a dense structure and simultaneously to bond the particles to the carrier web by the bonding agent and/or the synthetic resin composition.
