Flexible Delimiting Wall for Coil Padding Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional apparatuses for producing coil-like padding products require a reel for rolling up web-type padding material, which complicates the process and results in inconsistent density and padding properties, especially in the center of the coil.
Innovation Solution
An apparatus that uses a flexible delimiting means without a reel to roll up the web-type padding material, forming a curved delimiting wall that guides the material inwardly, allowing for adjustable rolling-up space and eliminating the need for a core, enabling continuous diameter increase and efficient production of coil-like padding products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a reel is used to roll up web-type padding material, then the rolling-up process can be performed, but the device complexity increases and the center density becomes inconsistent
Solution Approach 1:
The patent removes the reel from the system entirely. Instead of using a traditional reel structure, the invention employs a flexible delimiting means that forms a temporary rolling-up space without requiring a core or reel structure, thereby simplifying the device while maintaining the rolling-up function
Solution Approach 2:
The flexible delimiting means acts as an intermediary element between the web-type padding material and the rolling-up process. This flexible barrier forms the rolling-up space temporarily and allows the material to be rolled up without direct contact with a rigid reel, solving the density inconsistency problem
2Shape
If a reel is used for rolling up, then the coil can be formed, but the center density and padding properties become inconsistent
Solution Approach 1:
By removing the reel structure, the patent eliminates the source of density inconsistency. The flexible delimiting means allows uniform compression and rolling-up throughout the coil formation process, ensuring consistent density from the center outward without the structural constraints of a reel
3Device complexity
If the rolling-up space extent is fixed, then the apparatus structure is simple, but the diameter adjustment flexibility is limited
Solution Approach 1:
The flexible delimiting means provides a dynamic rolling-up space whose extent can change during operation. The flexibility allows the space to expand or contract to accommodate different coil diameters while maintaining a relatively simple apparatus structure, achieving both adaptability and structural simplicity
4Ease of operation
If a reel is used, then rolling up is enabled, but the construction and operation become more complex
Solution Approach 1:
The patent eliminates the reel and its associated complex construction. The rolling-up function is achieved through the flexible delimiting means that forms a temporary space, significantly simplifying the overall construction while maintaining operational ease through the intuitive pushing-in mechanism

AI summary
An apparatus for supplying a coil-like padding product for packaging purposes comprises a supply device for supplying a web-type padding material and also a rolling-up apparatus, which rolls up the web-type padding material to form the coil-like padding product. It is proposed that the rolling-up apparatus should comprise a flexible delimiting means, which can form an at least partially curved delimiting wall of an at least temporarily present rolling-up space, of which the extent is preferably alterable and which has an inlet for the web-type padding material, it being possible for the web-type padding material to enter into the rolling-up space through said inlet, wherein the web-type padding material is guided by the at least partially curved delimiting wall, this resulting in the formation of the coil-like padding product.
