Adhesive Tape Laminate for Cable Sheath Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating wraps for elongated objects, such as cable sets, are complex and costly due to the need for multiple adhesive tapes with adhesive coatings, which complicates handling and production.
Innovation Solution
A method involving a single adhesive tape with a first adhesive coating on its outer face and a second adhesive coating applied to its inner face, combined with an adhesive-free overlay strip, simplifies the process by eliminating the need for multiple adhesive tapes and allowing for a secure fixation and closure mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple adhesive tapes with adhesive coatings are used, then reliable fixation and protection are achieved, but device complexity and production costs increase
Solution Approach 1:
The patent combines multiple adhesive tapes into a single integrated adhesive tape structure with a base strip and multiple adhesive coatings applied to different surfaces. The first adhesive coating is applied to the outer face of the base strip, the second adhesive coating is applied to the inner face of the base strip, and the third adhesive coating is applied to the edge surface of the base strip. This merging eliminates the need for handling and laminating multiple separate adhesive tapes, thereby reducing production complexity while maintaining reliable fixation through the distributed adhesive coatings.
Solution Approach 2:
The single adhesive tape structure performs multiple functions that previously required separate components. The first adhesive coating provides primary bonding to the overlay strip, the second adhesive coating enables self-adhesion or bonding to underlying layers, and the third adhesive coating on the edge provides lateral fixation and sealing. This multi-functional design simplifies the overall structure while ensuring comprehensive fixation and protection.
2Object-affected harmful factors
If multiple adhesive tapes are laminated with offsets, then mechanical protection against scouring and rubbing is achieved, but manufacturing precision requirements increase
Solution Approach 1:
The patent merges multiple adhesive tapes into one integrated structure with adhesive coatings on different surfaces. The base strip provides structural integrity while the distributed adhesive coatings (outer face, inner face, and edge) create overlapping protection zones. This eliminates the need for precise offset lamination of multiple separate tapes, as the single structure inherently provides the protective coverage through its multi-surface adhesive application.
3Reliability
If adhesive tape width exceeds overlay strip width, then fixation strip is formed for securing, but material usage efficiency decreases
Solution Approach 1:
The patent applies adhesive coatings selectively to specific regions of the base strip rather than uniformly across the entire surface. The first adhesive coating is applied to the outer face, the second to the inner face, and the third to the edge surface. This localized adhesive application ensures that adhesive material is only present where needed for fixation, reducing waste while maintaining securing capability. The adhesive-free regions optimize material efficiency without compromising the fixation function.

Function Achieved in This Case
This approach reduces production complexity and costs while providing effective mechanical protection for elongated objects by creating a durable and secure wrap that can be easily applied and secured.
Implementation Method 1
adhesive tape consisting of a base strip and a first adhesive coating that essentially covers the full area of the base strip on its outer face is combined with an adhesive-free overlay strip to form a laminate
Implementation Method 2
the base strip of the adhesive tape is furnished essentially over a partial area with another second adhesive coating in addition to the first adhesive coating on its inner face

AI summary
The present invention relates to a method for the production of a cladding for elongated material (2), in particular a sheath for cable sets. In this method, an adhesive tape (3, 4) consisting of a carrier (4) and a first adhesive coating (3) which substantially fully covers the front side of the carrier (4) is combined with an adhesive-free carrier tape (5) such as to form a laminate (3, 4, 5). This is carried out such that the adhesive tape (3, 4) is applied to the carrier tape (5) with its first adhesive coating (3) in such a way that a first projection (Ü1) is defined along at least one of the two longitudinal edges of said adhesive tape. According to the invention, the carrier (4) of the adhesive tape (3, 4) is additionally provided with a further second adhesive coating (7) substantially in parts of its rear side.
