A marking means for timber packages (1), by which on the side (3) of the timber package are imprinted with a paint spray gun (2) the data relating to the timber package and to the goods contained therein. The paint gun (2) is movable under remote control in a coordinate-controlled plane beside the timber package (1), spraying the prescribed markings on the side of the timber package.
A method for the production of finished wood sheets from rough cut wood includes the steps of conditioning the rough cut wood, as necessary, to obtain a predetermined moisture content equivalent to a humidity of 50%. The conditioned rough cut wood is cut into predetermined dimensions using a sawdust-free process and then immediately dried to obtain a low moisture content. The dried wood is further treated using a grinding process to eliminate rough edges of the finished sheet.
A method for the production of finished wood sheets from rough cut wood includes the steps of conditioning the rough cut wood, as necessary, to obtain a predetermined mositure content equivalent to a humidity of at least 50%. The conditioned rough cut wood is cut into predetermined dimensions using a sawdust-free process and then immediately dried to obtain a low moisture content. The dried wood is further machined to eliminate rough edges of the finished sheet.
A lumber end sealing machine involves a pass-through design utilizing a single exhaust system and the use of traveling and rotating sealer paint spray guns. An exhaust chamber is centered over the conveyor with spray guns located at both the conveyor entrance and exit openings of the exhaust chamber. The spray guns are formed to both transversely and rotatingly pass through an end face of the package of lumber which is stopped at the center of the exhaust system. The spray guns are supported on a vertical rod suspended from a carriage with transverse movement through the use of a pneumatic rodless piston and rotational movement of the spray guns by rotation of the vertical rod by means of a cam follower mechanism engaged with a curved profile bar. The actual spraying of the sealer paint occurs during only a portion of the passage of the spray guns across an end face, the spraying beginning and stopping with the spray guns still located to the inside of the vertical side edges of the end face and with the spraying being directed outwardly toward the vertical side edge of the end face so as to mask the sides of the package. An alternative configuration of the invention includes fixed spray means centrally located along the sides within the exhaust chamber so as to additionally spray sealer paint inwardly on the sides of the package as it passes through the chamber.
