Asymmetric Adhesive Tape for Cable Wrapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current adhesive tapes for longitudinal wrapping of elongated goods, such as cables, are complex to produce and have high material costs due to the need for multiple adhesive strips, which also lead to weak points in the wrapping and increased adhesive consumption.
Innovation Solution
An adhesive tape with a band-shaped carrier made of aluminum composite material and a PET fabric carrier, where only one side has an adhesive layer, allowing for easy processing and reduced material usage, eliminating the need for narrow adhesive strips and ensuring a largely adhesive-free inner surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple adhesive strips are used for longitudinal wrapping, then the wrapping coverage is improved, but the production complexity and material costs increase
Solution Approach 1:
The patent combines multiple adhesive strips into a single continuous adhesive layer that extends across the entire width of the carrier web. This merging eliminates the need for separate adhesive applications and complex lamination machinery, while providing continuous adhesive coverage for reliable wrapping.
Solution Approach 2:
The single continuous adhesive layer serves multiple functions simultaneously: it provides complete surface coverage, eliminates weak points between strips, and simplifies the production process. This universal adhesive structure replaces the need for multiple discrete adhesive components.
2Reliability
If multiple adhesive strips are used for longitudinal wrapping, then the wrapping coverage is improved, but the adhesive consumption increases
Solution Approach 1:
By merging multiple adhesive strips into one continuous layer, the patent eliminates redundant adhesive application areas and overlapping regions, thereby reducing total adhesive consumption while maintaining complete coverage.
3Ease of manufacture
If narrow side adhesive strips are used, then the production complexity is reduced, but the wrapping reliability decreases due to small adhesive surface
Solution Approach 1:
Instead of using narrow adhesive strips at the sides, the patent inverts the approach by providing a continuous adhesive layer across the entire width of the carrier, ensuring maximum adhesive surface area and wrapping reliability.
4Productivity
If the adhesive tape is wound in rolls with both sides sticky, then the material utilization is improved, but the handling complexity increases due to sticky surfaces
Solution Approach 1:
The patent extracts the adhesive function to only one side of the carrier web, leaving the other side non-sticky. This allows the tape to be wound in rolls without self-adhesion problems, improving handling ease while maintaining complete adhesive coverage on the functional side.

AI summary
The adhesive tape (1) for longitudinal covering of an elongated product such as cable winding tape, comprises a band-shaped carrier (2), an adhesive layer (3) applied on a side of the carrier, and a second carrier (4) laminated on the adhesive layer. The second carrier has smaller breadth (B4) than the breadth (B2) of the first carrier. The second carrier extends to a lateral edge (K4) with a lateral edge (K2) of the first carrier in close position. The first carrier projects with the adhesive layer with respect to or reciprocal to the other lateral edge (K4) of the second carrier.

The second carrier extends to a lateral edge (K4) with a lateral edge (K2) of the first carrier in close position. The first carrier projects with the adhesive layer with respect to or reciprocal to the other lateral edge (K4) of the second carrier. The second carrier is arranged asymmetrically to a longitudinally running middle axis (X-X) of the first carrier, projects on the other side of the first carrier opposite to the lateral edge of the first carrier, and consists of two separated carrier parts, where the first carrier part has a first breadth (B4a) and the second carrier part has a second breadth (B4b). The sum of the breadth of the carrier parts is smaller than the breadth of the first carrier. The first carrier and/or the second carrier consist of a film, a film composite material or non-woven. Covered areas (5) of the first carrier are covered with a release paper or a release film laterally with respect to the second carrier. The adhesive layer has a weight per unit area of 70-140 g/m 2>in the presence of textile carriers and a weight per unit area of 40-80 g/m 2>in the presence of carriers consisting of films.
