Glue Wave Arresting Arrangement for Corrugated Board Lamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for producing laminated endless webs of corrugated cardboard often apply glue unevenly, impairing the glue connection between the corrugated web and the cover web.
Innovation Solution
Incorporating a glue wave arresting arrangement within the glue container, featuring openings that slow down and stabilize the glue flow, preventing waves and ensuring even application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If glue application roller and metering roller rotate to apply glue, then glue application function is achieved, but glue waves form causing uneven application
Solution Approach 1:
A wave-arresting arrangement with baffle elements is introduced as an intermediary component in the glue container. These baffles intercept and dampen glue waves before they reach the application rollers, allowing continuous rotation and glue application while maintaining surface stability. The baffles act as mediators between the rotating rollers and the glue reservoir, preventing direct transmission of disruptive forces.
Solution Approach 2:
The invention converts the harmful effect of glue waves (caused by roller rotation and glue inflow) into a beneficial controlled flow pattern. The wave-arresting arrangement redirects the kinetic energy of incoming glue and the rotational disturbances into a calm, uniform flow that exits through openings in the baffles, ensuring consistent glue application without waves.
2Quantity of substance
If glue flows freely into glue container, then glue supply is maintained, but glue waves and spillage occur
Solution Approach 1:
The glue container is segmented into multiple zones by wave-arresting baffles with controlled openings. Glue flows through these segmented sections in a controlled manner, with each baffle creating a separate flow zone that dissipates energy and prevents wave formation. This segmentation maintains adequate glue supply while eliminating the harmful effects of uncontrolled flow.
Solution Approach 2:
The wave-arresting arrangement incorporates porous or perforated baffle elements that allow glue to pass through while filtering out waves and turbulence. The porous structure of the baffles enables selective passage of glue (liquid phase) while blocking the transmission of wave energy, thus maintaining supply while preventing spillage.

Function Achieved in This Case
This solution ensures a uniform and stable glue connection between the corrugated web and the cover web, preventing glue escape and spillage, and facilitating a consistent glue layer formation.
Implementation Method 1
The openings preferably reduce flow of the glue in the glue container
