Cutting Device Clamping Element for Clean Veneer Edge Trimming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting devices for coating materials, such as those used for edge bands, often produce unwanted chips due to the jerky cutting motion, which can lead to malfunctions and inefficiencies in the cutting process.
Innovation Solution
A cutting device equipped with a clamping element that projects beyond the cutting edge and clamps the coating material between itself and a counter-bearing, ensuring a clean cut by preventing the coating material from being cut twice.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cutting device is pivoted or displaced to follow the moving coating material, then the cutting process can be performed on fed material, but coating material chips are thrown uncontrollably causing malfunctions
Solution Approach 1:
The clamping element is positioned in advance to engage with the coating material before the cutting blade reaches it. This preliminary clamping action secures the material in a controlled manner, preventing the jerky movements that cause chip throwing while allowing the cutting process to proceed smoothly on fed material.
Solution Approach 2:
The clamping element acts as an intermediary between the cutting blade and the coating material. It provides a controlled interface that manages the interaction between the blade and material, preventing direct contact that causes uncontrolled chip ejection while enabling the cutting operation to continue on moving material.
2Device complexity
If the cutting edge hits the coating material without clamping, then the cutting process is simple, but the coating material is cut twice creating shreds
Solution Approach 1:
The clamping element engages with the coating material before the cutting blade makes contact. This preliminary positioning ensures that the material is securely held in the correct position, preventing the blade from penetrating too deeply or creating multiple cuts that would result in shreds.
Solution Approach 2:
The clamping element serves as an intermediary that controls the interaction between the cutting blade and coating material. It manages the cutting process to ensure a single clean cut through the material thickness, preventing the double-cut condition that creates shreds while maintaining operational simplicity.
3Force
If the clamping element protrudes beyond the cutting edge, then the coating material is clamped effectively, but the clamping element must deform elastically during cutting
Solution Approach 1:
The clamping element is designed with specific material properties and geometric parameters that allow it to deform elastically within controlled limits during cutting. This parameter optimization enables effective clamping force to be applied while the element returns to its original position after deformation, maintaining functionality without excessive complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The use of a clamping element in the cutting device prevents the formation of shreds and ensures a clean, controlled cut, reducing the risk of malfunctions and improving the efficiency of the cutting process.
Implementation Method 1
the clamping element is further designed such that in the cutting position it deforms elastically and/or shifts relative to the cutting knife to such an extent that it springs back behind the cutting edge of the cutting knife relative to the cutting knife

AI summary
The cutting device (1) for cutting coating materials comprises a cutting blade (10) with a cutting edge (10a) and a drive (2) coupled to the cutting blade (10). The drive (10) is designed to move the cutting blade (10) from a ready position to a cutting position. The cutting device (1) further comprises a counter bearing (11) which serves to support a coating material (K) during cutting. A clamping element (12) is arranged on the cutting blade (10), which is designed to deform elastically in the cutting position and/or be displaced relative to the cutting blade (10) to such an extent that it springs back behind the cutting edge (10a) of the cutting blade (10).
