Rotary Edgeband Receiving Device Radial Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing edging systems for wood-based panels face challenges with uncontrolled unwinding and misalignment of edging strips due to their design, requiring significant space for internal clamping mechanisms, which is problematic when multiple devices are arranged together in industrial settings.
Innovation Solution
A receiving device with a slim internal clamping mechanism that translates rotational mobility of an actuating element into linear displacement of supporting jaws, ensuring precise and self-locking clamping without the need for extensive space, utilizing a hub body with spring-loaded supporting jaws and a torsion-proof disk element for secure edgeband roll handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional internal clamping mechanisms are used to secure edging tape rolls, then reliable clamping is achieved, but the device requires significant space which prevents high-density arrangements
Solution Approach 1:
The patent transitions the clamping mechanism from axial movement (along the rotation axis) to radial movement (perpendicular to the axis). The support jaw moves radially inward to clamp the tape roll, eliminating the need for axial displacement space. This dimensional change enables compact high-density arrangements while maintaining reliable clamping through radial bracing of the tape layers.
2Productivity
If multiple receiving devices are arranged next to each other for industrial edging, then productivity is improved, but space requirements increase significantly
Solution Approach 1:
By changing the clamping mechanism from axial to radial movement, the patent dramatically reduces the footprint of each receiving device. This enables high-density arrangements where multiple devices can be placed close together on shelves, cupboards, or trolleys, thereby increasing productivity without proportionally increasing installation area.
3Volume of moving object
If edging rolls are stored compactly, then space efficiency is improved, but controlled unwinding and alignment become difficult
Solution Approach 1:
The support jaw is pre-positioned in a retracted state during storage, allowing compact rolling of edging tapes without interference from clamping components. When operation is required, the support jaw is actuated radially inward to secure the roll, providing controlled unwinding and preventing misalignment between windings. This preliminary positioning enables both compact storage and easy handling.
Applied Scientific Principles
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 solution provides a compact, stable, and precise clamping system that prevents slipping and misalignment of edging tapes, allowing for efficient storage and handling of edgeband rolls with minimal space requirements, even in high-density arrangements.
Implementation Method 1
at least one spring element (8a-8c) which acts on the at least one support jaw (6a-6c) and is designed to spring-load the linearly displaceable support jaw (6a-6c) at least in sections
Implementation Method 2
spring-loaded supporting jaws
Implementation Method 3
The translation can have a sufficiently high level of self-locking to maintain the required voltage. This effectively prevents any 'slipping' between the rotating hub body and an edging tape roll placed on it

AI summary
A receiving device (1) for an edgeband roll comprises a hub body (4) rotatably mounted about an axis of rotation (X), and a disc element (2) extending in a plane perpendicular to the axis of rotation (X). The hub body (4) has at least two support jaws (6a-6c) designed for at least indirect internal clamping of the edgeband roll, which can be at least partially mounted on it. A locking mechanism (11) has an actuating element (12) that is rotatable relative to the hub body (4) about the axis of rotation (X) within limits, and at least one arm (13a-13c) that couples the actuating element (12) to one of the support jaws (6a-6c). The rotational mobility of the actuating element (12) can be translated into a linear displacement of the support jaw (6a-6c) coupled to the arm (13a-13c) radially to the axis of rotation (X).
