Method and apparatus for producing a board

A method of producing a spreading material mat, the method comprising:

• providing particulate material comprising or consisting of particulate wooden material,
• producing glued particulate material by applying an adhesive to the particulate material,
• forming a spreading material mat having a longitudinal direction and having a transversal direction perpendicular to the longitudinal direction by homogeneously spreading the glued particulate material onto a conveyor on which the spread glued particulate material is conveyed in a conveying direction that is parallel to the longitudinal direction of the spreading material mat, wherein the glued particulate material is spread onto the conveyor over a length of a spreading sector extending in conveying direction such that, in conveying direction, the spread glued particulate material is accumulated to the spreading material mat over the length of the spreading sector,
• wherein a reinforcement material is applied to the spread glued particulate material parallel to the conveying direction by spraying, sputtering, and/or injecting
• during forming the spreading material mat and/or
• after forming the spreading material mat and before any pressing of the spreading material mat such that the spreading material mat has at least one longitudinal reinforcement zone containing the reinforcement material.

An apparatus for producing at least one board for production of panels, the apparatus comprising

• a gluing device for applying an adhesive to a particulate material which comprises or consists of particulate wooden material and thus producing glued particulate material,
• a conveyor on which the glued particulate material can be conveyed in a conveying direction,
• a spreading head for homogeneously spreading the glued particulate material onto the conveyor within a spreading sector such that a spreading material mat having a longitudinal direction parallel to the conveying direction and having a transversal direction perpendicular to the longitudinal direction of the spreading material mat can be formed on the conveyer and the spread glued particulate material is accumulated to the spreading material mat in conveying direction over the length of the spreading sector,
• at least one continuous belt press for producing a board by pressing the spreading material mat, and
• at least one reinforcement material addition means for applying a reinforcement material to the spread glued particulate material
• during forming the spreading material mat and/or
• after forming the spreading material mat and before any pressing of the spreading material mat such that the spreading material mat has at least one longitudinal reinforcement zone.
