Scattering Head Spindle Rotation for OSSB Panel Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The industrial production of OSSB panels is difficult and expensive, and straw particles longer than 102 mm are not suitable for filtering or screening to produce multi-layer panels, limiting their mechanical and regulatory compliance for construction industry standards.
Innovation Solution
A scattering head with rotatable spindles and a control unit allowing two operation configurations distributes binder-covered material particles on a conveyor belt, enabling the production of OSSB panels with varying particle length distributions and properties, reducing production effort and costs by allowing the same scattering head to produce different products.

1Quantity of substance
If straw particles longer than 102 mm are used in OSSB panel production, then the use of agricultural waste material is improved, but the suitability for filtering or screening to produce multi-layer panels deteriorates
Solution Approach 1:
The scattering head employs rotatable spindles that can change rotation direction dynamically. By reversing the rotation direction, the same scattering head can effectively distribute both long straw particles (>102mm) and shorter particles, enabling multi-layer panel production without requiring separate screening equipment for different particle sizes
Solution Approach 2:
The scattering head is designed to perform multiple functions: it can distribute long straw particles in one rotation direction and shorter particles in the opposite rotation direction. This universal device replaces the need for separate screening and distribution equipment, allowing the same apparatus to handle diverse particle sizes for different panel layers
2Adaptability or versatility
If multiple scattering heads are used to produce different products, then the versatility of product production is improved, but the device complexity and production costs increase
Solution Approach 1:
The scattering head incorporates rotatable spindles with controllable rotation directions. By dynamically changing the rotation direction of the spindles, a single scattering head can adapt to produce different panel types and configurations, eliminating the need for multiple fixed scattering heads for different products
Solution Approach 2:
The system changes operational parameters (rotation direction of spindles) to achieve different production outcomes. This parameter variation allows one scattering head to perform the work of multiple scattering heads, reducing device complexity while maintaining product versatility
3Adaptability or versatility
If the scattering head is designed to handle long straw particles, then the processing capability for agricultural waste is improved, but the setup and maintenance effort increases
Solution Approach 1:
The rotatable spindles with reversible rotation provide a dynamic solution for handling long straw particles. The same mechanism that enables long particle processing also allows easy switching to handle shorter particles, minimizing setup changes and maintenance requirements while maintaining high processing capability

AI summary
The invention concerns a scattering head, a scattering arrangement as well as a methodto produce an OSSB panel (Oriented Structural Straw Board) as well as an OSSBpanel and a layer thereof. By means of a control unit of the scattering head with at least two operation configurations, wherein the direction of rotation of at least one spindle is defined by the operation configuration, different products can be produced by selecting or activating different operation configurations. An OSSB panel with material particles of the length L within a range of 0 < L ≤ 120 mm, wherein material particles of a length L > 9,5 mm in a first surface of the layer with a portion of >30 % and/or in a second layer of the selfsame layer with a portion < 30 % are comprised, enables good usage in construction industry.
