Patent DE-3916099-A1 (DE)
Inventor: HOLZER HERBERT DR
IPC: B32B27/04
Filed: 1989-05-17
Abstract: Laminate plates (1) are manufactured by pressing a stack (2) of core sheets of phenolic-resin-impregnated paper (3) and a covering layer (4) of melamine-resin-impregnated decorative paper under the effect of heat and pressure. An inlay sheet (5) acts as the transfer sheet for surface coating and, in a coating device (8), is given a coating (6) which may, for example, be a polyvinyl butyral film. With the coating (6), the inlay sheet (5) is laid on the covering layer (4). In the subsequent pressing operation, the coating (6) is transferred to the covering layer (4) and forms a surface coating (6') on the laminate plate (1).
