A method for treating a piece of wood impregnates the piece of wood with a water repellent, wherein the water repellent is solid at ambient temperatures. The method includes the steps of providing a piece of wood to be treated; heating the piece of wood for a predetermined period of time, the piece of wood being heated at a temperature A; subsequently immersing at least a portion of the piece of wood in a bath of liquefied water repellent, the bath being at a temperature B, for a predetermined period of time. Thereafter the piece of wood is removed from the bath and allowed to cool. The temperature A is above 100 C. and the temperature B is below 100 C. but above a liquefying point for the water repellent, and a differential between temperatures A and B is at least 60 C.

Coating apparatus with base material height changing device configured to selectively eject compressed gas

A coating apparatus includes a transport roll for transporting a base material, a slit die facing a lower surface of the base material, a coating liquid supply controller for switching on and/or off in supply of a coating liquid to the slit die, and a base material height changing device for ejecting compressed gas onto the lower surface of the base material during a specific period from a termination of the supply of the coating liquid to the slit die to a restart of the supply of the coating liquid to the slit die.

In a lumber factory, an automated laminated veneer lumber (LVL) process supported by a lumber production line employing a cross-cutting and rip-sawing stage, a dip-coating stage, a spray-coating stage, a print-marking stage, and a stacking, packaging and wrapping stage. At the dip-coating stage, cross-cut and rip-sawed LVL product is automatically transported and submerged through a dipping reservoir containing clean fire inhibiting chemical (CFIC) liquid, and then wet-stacked and set aside to dry. Once dried, the dip-coated LVL products are returned to the production line and sprayed coated with a moisture, fire and UV protective coating at the spray-coating stage, and then passed through a drying tunnel for quick drying of the spray-coating to produce Class-A fire-protected LVL products. The Class-A fire-protected LVL products are stacked, packaged and wrapped at the stacking, packaging and wrapping stage into a package of Class-A fire-protected LVL products, ready for shipping.
