Multi-Page Adhesive Label Single-Pass Punching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of multi-page adhesive labels is complex and costly due to the need for multiple cutting operations and handling steps, making it inefficient and expensive.
Innovation Solution
A method that uses a single pass of a punching tool to cut and form a multi-page adhesive label with a peelable adhesive layer, allowing for simultaneous cutting and weeding operations to produce a label with a gripping device, reducing production time and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple cutting operations and handling steps are used to produce multi-page adhesive labels, then the labels can be manufactured with proper structure and fasteners, but the production process becomes complex and costly
Solution Approach 1:
The patent combines multiple cutting operations into a single punching operation. The punching tool simultaneously creates the external contour, internal contours, and forms fasteners by making multiple indentations in one pass through the superimposed data sheets and adhesive layers, eliminating the need for separate cutting steps for each feature.
Solution Approach 2:
The data sheets are pre-superimposed on the adhesive backing sheet in the correct arrangement before the punching operation. This preliminary positioning allows the single punching pass to efficiently create all necessary cuts and fasteners without requiring subsequent handling or repositioning operations.
2Manufacturing precision
If multiple cutting operations are used to create fasteners and contours, then the label structure is proper, but production time increases
Solution Approach 1:
The punching tool integrates multiple cutting functions into a single operation. By equipping the tool with multiple indentations that engage different layers simultaneously, it creates external contours, internal contours, and fasteners in one pass, maintaining precision while dramatically increasing production speed.
Solution Approach 2:
The punching operation continues uninterrupted through all layers in a single pass. The tool maintains continuous contact with the superimposed sheets, creating all necessary features without stopping or repositioning, thereby eliminating idle time between cutting operations while preserving manufacturing precision.
3Reliability
If multiple handling operations are performed during manufacturing, then the labels are produced correctly, but production costs increase
Solution Approach 1:
The patent merges multiple handling operations into a single integrated punching process. The tool performs contour cutting, fastener formation, and layer separation preparation all in one operation, reducing the number of handling steps and associated costs while maintaining reliable label production.
Solution Approach 2:
The punching operation itself creates the separation features and fasteners that enable subsequent automated or manual separation of the label components. The process prepares the label for final assembly without requiring additional specialized handling operations, allowing the system to serve itself.

AI summary
A process for producing a multi-page adhesive label comprising the following steps: - superimposing, on an adhesive backing sheet, a first layer of adhesive, a first data sheet, a second layer of adhesive, and a second data sheet - cutting a first outline in both the first data sheet and the second data sheet; and a second outline in the second data sheet - peeling from the adhesive backing sheet the portion of the first data sheet that lies around the first outline, and the portion of the second data sheet that lies around the second outline.
