Embossed Packaging Lids Partial Embossing Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing embossed lids or labels result in reduced printing quality due to whole surface embossing, which affects color shine and intensity, as they are typically embossed during the die-cutting process for easy separation, contradicting the need for precise partial embossing to maintain aesthetic and protective functions.
Innovation Solution
A device and method that utilize multiple die-cutting and embossing tools aligned in the longitudinal direction, allowing for precise partial embossing of lids or labels, where embossing tools are synchronized with die-cutting tools to apply embossing on specific areas, ensuring accurate positioning and separation while maintaining printing quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If whole lid surface embossing is applied during die-cutting process, then easy separation of lids is achieved, but printing quality is lost due to surface relief affecting color shine and intensity
Solution Approach 1:
The patent applies local embossing only at specific locations (e.g., center, edges, or patterns) rather than the entire surface. The embossing tools are positioned to create localized relief structures that facilitate separation while leaving the majority of the printed surface flat and intact, thus preserving printing quality in the unembossed areas.
Solution Approach 2:
The embossing process is segmented into multiple independent embossing zones or patterns distributed across the lid surface. Instead of a single continuous embossing action, the system applies discrete embossing elements that can be independently controlled, allowing separation functionality while maintaining printed areas.
2Manufacturing precision
If multiple embossing tools are combined with die-cutting tools in the longitudinal direction, then precise partial embossing position and height is achieved, but device complexity increases
Solution Approach 1:
The patent combines multiple embossing tools with die-cutting tools in a single tool housing or assembly, where the embossing tools are aligned with the die-cutting tool in the longitudinal direction. This integration allows synchronized operation of embossing and die-cutting functions, reducing the need for separate tooling systems and simplifying the overall device architecture despite having multiple embossing elements.

AI summary
Device for producing embossed cover elements for emballages, which cover elements are embossed in and die-cut from a pseudo-endless sheet material which runs through the device in a longitudinal direction at temporary standstill of the sheet material, the device comprising at least one M (M≥1) die-cutting tools and M x N (N≥2) embossing tools, wherein N different embossing tools are combined with each die-cutting tool in the longitudinal direction.
