Wire Label Carrier Strip Segmentation for Printer Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing labeling devices for electronic printing machines face issues with stiff and bulky carrier strips that distort images, are difficult to move through printers, and are costly due to unnecessary width, and struggle with efficient label registration and removal.
Innovation Solution
A carrier strip with two backing layers and an adhesive layer, where predetermined areas are exposed to create adhesive windows covered by tabs, allowing flexible label placement and easy removal, and featuring frangible regions for multiple printing and separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a stiff and thick carrier strip is used to support labels during printing, then the labels are properly supported and aligned, but the carrier strip distorts printed images, is difficult to move through printers, and increases material costs
Solution Approach 1:
The carrier strip is segmented into multiple layers (first backing layer, adhesive layer, second backing layer) with different functional properties. The first backing layer provides structural support while the second backing layer is made frangible to allow easy separation, resolving the contradiction between needing strength for support and flexibility for easy movement and removal through printing machines.
Solution Approach 2:
Different regions of the carrier strip have different properties: the first backing layer is strong and flexible for support, the adhesive layer provides controlled adhesion only where needed, and the second backing layer is frangible for easy removal. This local differentiation allows each layer to optimize its function without compromising the others.
2Ease of operation
If a wide carrier strip is used to accommodate track-driven or pin feed mechanisms, then the carrier can be moved and rotated, but the material cost increases and the width is greater than necessary
Solution Approach 1:
The patent replaces traditional mechanical drive systems (track-driven or pin feed mechanisms requiring wide carriers) with an adhesive-based attachment system. Labels are secured through adhesive windows in the second backing layer, eliminating the need for wide carrier strips with mechanical feed features, thus reducing material usage while maintaining ease of operation.
3Strength
If labels are attached to the carrier strip with extensive adhesive contact, then the labels are securely held during printing, but the labels become difficult to remove after printing
Solution Approach 1:
The adhesive layer provides secure attachment only at specific locations where windows are formed in the second backing layer, allowing labels to be firmly held during printing while enabling easy removal afterward. The adhesive contact is localized to essential areas only, not the entire label surface.
Solution Approach 2:
The attachment system is segmented into adhesive windows that provide controlled, localized adhesion points rather than continuous adhesive coverage. This segmentation allows labels to be securely held during the printing process while facilitating easy removal once printing is complete.
4Stability of the object's composition
If a thick carrier strip is used to provide structural support, then the carrier maintains its shape, but it is difficult to feed through printing machines that require negotiation of curves and bends
Solution Approach 1:
The carrier strip is divided into multiple layers with different mechanical properties. The first backing layer provides structural integrity and stability, while the frangible second backing layer allows the carrier to flex and bend easily during feeding through printing machines. The layered segmentation resolves the contradiction between structural stability and flexibility.
Solution Approach 2:
The carrier strip uses composite construction with a first backing layer of strong, flexible material and a second backing layer of frangible material. This composite structure combines the advantages of both materials: structural integrity from the first layer and flexibility for curving from the second layer.

Function Achieved in This Case
The solution enables easier feeding and printing of labels, minimizes distortion, reduces material costs, and facilitates efficient label registration and removal, while maintaining structural support for the printing process.

AI summary
A label assembly comprised of a carrier strip and a plurality of labels. The carrier strip comprises at least a first backing layer and a layer of adhesive material located over said first backing layer. A second backing layer may be located over said adhesive layer. Predetermined areas are removed from the second backing area to expose the adhesive layer. Cover tabs overlay portions of the exposed adhesive layer with the labels being removably adhered to the carrier strip on the remaining exposed adhesive layer. The labels may be provided with frangible regions for partitioning the wire label. The frangible regions include both severed portions and points of attachment.
