Solution Overview

Problem

Manufacturers face economic inefficiencies and fluctuating demand challenges when producing both OSB and chipboard, as they need separate production systems, leading to increased costs and capacity issues due to the differences in chip and strand production processes.

Innovation Solution

A method that allows the use of a chipboard production system to produce OSB boards by adapting the process to include both strands and chips, using a top layer spreading device to scatter strands and chips onto a forming belt, and pressing them into an OSB board of desired thickness, enabling simultaneous production on both systems.
