Partial Non-Slip Lacquer Coating for Faster Web Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-slip coatings for materials like paper webs are expensive, poorly bonded at glue points, and slow to dry, leading to increased costs, processing difficulties, and waste, especially when applied over entire surfaces.
Innovation Solution
Applying an anti-slip coating in a grid pattern over partial areas of the surface, allowing for adjustable friction levels by varying the coverage ratio and layer thickness, which reduces material usage and facilitates easier gluing and faster processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire surface of the carrier is provided with a covering layer of anti-slip material, then the coefficient of friction is maximized and processing properties are improved, but the costs increase due to expensive anti-slip materials
Solution Approach 1:
The patent divides the carrier surface into multiple zones with different coating densities. Instead of applying anti-slip material uniformly across the entire surface, the coating is segmented into high-density areas (where friction is critical) and low-density or uncoated areas (where friction requirements are lower). This segmentation maintains sufficient processing properties while reducing the total quantity of expensive anti-slip material required.
Solution Approach 2:
The patent implements local quality by varying the coating density across different regions of the carrier surface. Areas requiring high friction for processing are coated with higher density anti-slip material, while other areas use lower density or no coating. This localized approach optimizes friction properties where needed without unnecessarily applying material across the entire surface, thereby reducing costs.
2Reliability
If the carrier is provided with a covering layer to improve friction, then processing properties are enhanced, but the drying time increases which reduces overall processing speed
Solution Approach 1:
The patent applies partial coating rather than full-surface coating, using just enough anti-slip material in strategic areas to achieve the required friction properties for processing. By avoiding excessive coating application across the entire surface, the amount of material requiring drying is reduced, thereby decreasing drying time and increasing overall processing speed while still maintaining sufficient friction where needed.

AI summary
The invention relates to a method for producing a non-slip coating on a carrier (1) which is in the form of a sheet or can be unwound off a roll, for improving the friction-related treatment characteristics of the carrier (1) for subsequent treatment steps, such as cutting, stamping or folding processes, subsequent transport processes, or subsequent storing. A covering layer (3) consisting of non-slip material is applied to at least one of the two surfaces (5) of the carrier (1). According to the invention, lacquer is used as a covering layer (3), said lacquer being applied only to certain parts of the surface (5) of the carrier (1). The invention also relates to a strip-type or sheet-type material consisting of a carrier (1), and a covering layer (3) consisting of a non-slip material applied to at least one of the two surfaces (5) of the carrier (1). The covering layer (3) is a layer of lacquer which is applied only to sections of the surface (5) of the carrier (1).
