Abstract
A method for producing a panel including a core and a decorative surface layer is disclosed. The method includes the step of applying a dry powder layer on the core. The method includes the step of applying steam on a dry powder layer on the core. Thereafter heat and pressure are applied to the powder layer in order to bond the powder together.
Claims26
A method comprising:
- applying a dry powder layer on a core, the dry powder layer comprising a mix of wood fibers and a binder;
- subsequently applying steam directly onto the dry powder layer while the dry powder layer is on the core to form a stabilized powder layer on the core;
- and
- subsequently bonding the powder in the stabilized powder layer together into a cured layer by applying heat and pressure, and thereby forming a panel comprising the core and the cured layer.
