Abstract
The object of the invention is to provide a process for producing a woody composite material having strength endurable for use as a structural material, even when using short woody chips of 15 cm or less in length. This invention relates to a process for producing a woody composite material which comprises the steps comprising blending woody chips of 1 to 15 cm in length with a binder, piling up the woody chips so as to be oriented in the longitudinal direction thereof to form a mat, and pressurizing and heating the mat from a direction perpendicular to both the longitudinal direction and vertical direction of the woody chips.

A process for producing a woody composite material
- which comprises the steps comprising
- blending woody chips of 1 to 15 cm in length with a binder,
- piling up the woody chips so as to be oriented in the longitudinal direction thereof to form a mat, and
- pressurizing and heating the mat from a direction perpendicular to both the longitudinal direction and vertical direction of the woody chips.
A process for producing a woody composite material
- which comprises the steps comprising
- blending woody chips of 1 to 15 cm in length with a binder,
- piling up the woody chips so as to be oriented in the longitudinal direction thereof to form a mat, and
- rotating the mat by 90° rightward or leftward around the longitudinal direction of the woody chips as the axis of rotation and then pressurizing and heating the mat from the vertical direction.
A process for producing a woody composite material
- which comprises the steps comprising
- blending woody chips of 1 to 15 cm in length with a binder,
- piling up the woody chips to a predetermined height while orienting them in the longitudinal direction thereof in the inside of a guide arranged so as to regulate the outside of the woody chips in a direction perpendicular to both of the longitudinal direction and vertical direction of the woody chips, to form a mat, and
- removing the guide and then pressurizing and heating the mat from the vertical direction.
A process for producing a woody composite material
- which comprises the steps comprising
- blending woody chips of 1 to 15 cm in length with a binder,
- piling up the woody chips so as to be oriented in the longitudinal direction thereof to form a mat,
- pinching the mat with 2 movable plates from a direction perpendicular to both the longitudinal direction and vertical direction of the woody chips and then pressurizing the mat with the plates while pushing the woody chips upward, to reduce the area of the mat observed from the vertical direction, and
- pressurizing and heating, from the vertical direction, the mat of which area was reduced when observed from the vertical direction.

- which comprises the steps comprising
- blending woody chips of 1 to 15 cm in length with a binder,
- piling up the woody chips so as to be oriented in the longitudinal direction thereof to form a mat, and
- passing the mat through 2 plates having a decreasing space therebetween toward the direction of movement while pushing the woody chips upward, to reduce the area of the mat observed from the vertical direction, and
- pressurizing and heating, from the vertical direction, the mat of which area was reduced when observed from the vertical direction.
