Veneer Sheet Laying Method for Glued Laminated Wood
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to effectively lay a veneer sheet over the lower surface of a base material in a horizontal position during the manufacturing of glued laminated wood, requiring secure support and precise alignment for successful bonding.
Innovation Solution
A method involving the use of a first support means to initially support the base material, followed by a second support means that partially supports the veneer sheet, allowing it to droop and come into contact with the base material, with controlled movement of support plates and heated plates for hot pressing, ensuring proper alignment and bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base material is securely supported by a conveyer during veneer sheet laying, then the laying operation can be performed successfully, but the base material must be moved into the pressing region and supported throughout the process
Solution Approach 1:
The support function is divided into two separate support means: a first support means that supports the base material and a second support means that supports the veneer sheet. This segmentation allows each support means to be optimized for its specific function and enables independent movement and retraction, resolving the contradiction between reliable laying operation and device complexity.
2Reliability
If the veneer sheet is fed to a movable metal carrier and pressed to the base material, then bonding can be achieved, but the base material must be moved by a conveyer and supported by the same conveyer
Solution Approach 1:
The support and pressing functions are segmented into separate components: the first support means for base material support, the second support means for veneer sheet support, and heated plates for pressing. This segmentation simplifies operation by allowing each component to perform its specific function independently without requiring complex coordinated movement of a single conveyer system.
3Ease of manufacture
If no support means is used for the veneer sheet, then the process is simpler, but the veneer sheet cannot be properly aligned and contacted with the base material
Solution Approach 1:
The support function for the veneer sheet is extracted as a separate second support means, which can be selectively activated only when needed for veneer sheet laying. This extraction maintains process simplicity by using a separate, dedicated support mechanism rather than complicating the entire system, while still achieving precise alignment and contact through controlled positioning.

AI summary
The present invention discloses a method for laying a sheet (27) over the lower surface of a base material disposed in a generally horizontal position. According to the method, the base material is supported at the lower surface thereof by a first support means (23), and the sheet is placed immediately below and in facing relation to the lower surface of the base material and then supported at the lower surface thereof by a second support means (5). The sheet and the base material are made to be in contact with each other over partial surfaces thereof. Subsequently, the first support means (23) is moved away from the base material and the sheet and the base material are placed together on a rigid horizontal surface (1) so that the sheet is laid substantially over the entire lower surface of the base material.
