Folding Device for Corrugated Cardboard Web
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The folding of large-format endless webs of corrugated cardboard often results in unwanted kinks due to inefficiencies in existing folding methods.
Innovation Solution
A device with a movable engagement member featuring finger-shaped projections is used to lift and fold the corrugated cardboard web along a predetermined trajectory, minimizing contact and reducing kinking by allowing the web to be folded along predetermined bending points created by embossing rollers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional folding methods are used for large-format endless webs of corrugated cardboard, then the folding process can be performed, but unwanted kinks are generated in the webs
Solution Approach 1:
The engagement member with finger-shaped projections is positioned and moved along a predetermined trajectory before the folding action to create bending points in the web. This preliminary positioning ensures that the web is folded at the correct locations and angles, preventing kinks from forming during the folding process.
Solution Approach 2:
The engagement member acts as an intermediary tool between the folding mechanism and the web. Its finger-shaped projections temporarily engage with the web to guide and control the folding process, lifting the web off the contact surface and directing it along a precise path to eliminate harmful kinks.
2Manufacturing precision
If the web is folded using traditional contact-based methods, then folding can be achieved, but the web may sag or deflect during the process
Solution Approach 1:
The engagement member is designed to be movable along a predetermined trajectory, allowing dynamic adjustment of the folding path. This dynamic movement enables the system to adapt to the web's position and maintain precise folding accuracy while preventing sagging or deflection through controlled engagement and release of the finger-shaped projections.

AI summary
A device for folding an endlessly producible web of corrugated cardboard comprises a stand with two retaining members, at least one engagement member mounted in the stand, the engagement member comprising at least one projection which comprises at least one free end forming a contact edge, and at least one driving device for moving the at least one engagement member, with the at least one engagement member being movably mounted in the stand in such a way that the contact edge is movable at an angle relative to the contact surface along a predetermined trajectory so as to bring the contact edge into engagement with the web of corrugated cardboard sliding on the contact surface.
