Use of an adhesive tape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive tapes used for wrapping cable bundles in automobiles lack a reliable method to verify the correct installation of tapes that meet specific requirements, such as temperature resistance, abrasion resistance, and noise dampening, especially after installation, due to the lack of visible differentiation between tapes.
Innovation Solution
Incorporating a marking thread into the fabric backing of adhesive tapes that encodes properties like temperature resistance, abrasion resistance, and noise reduction, using contrasting colors and surface finishes, allowing for visible identification of tape properties even after installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive tapes are used for wrapping cable bundles in automobiles, then they provide temperature resistance, abrasion resistance, and noise dampening, but it becomes difficult to verify the correct installation and identify tape properties after installation
Solution Approach 1:
The patent applies different colors to marking threads woven into the adhesive tape to encode specific properties such as temperature resistance, abrasion resistance, and noise dampening. This allows quality control personnel to visually identify tape properties after installation without requiring additional marking processes or complex identification systems.
2Ease of operation
If packaging or markings are placed on the inside of the roll core, then adhesive tapes can be differentiated for selection, but no verification is possible after installation in the wiring harness
Solution Approach 1:
The patent segments the identification function by incorporating distinct marking threads with different colors and patterns directly into the adhesive tape structure. This allows the tape to carry its own identification information both during selection (before installation) and after installation, eliminating the need to rely solely on packaging markings.
Solution Approach 2:
The marking threads are incorporated into the adhesive tape during the manufacturing process, before the tape is installed. This preliminary encoding of identification information ensures that the tape is self-identifying throughout its service life, from selection to final installation verification.
3Ease of operation
If a continuous sewing thread is used as a marking, then positioning aid is provided for winding, but additional manufacturing processes and sewing steps are required
Solution Approach 1:
The patent merges the marking function with the structural fabric backing of the adhesive tape by weaving marking threads directly into the fabric during the textile manufacturing process. This eliminates the need for separate sewing or attachment operations, reducing manufacturing complexity while maintaining the positioning and identification functions.
Solution Approach 2:
The marking threads are incorporated into the fabric backing during the textile manufacturing process, before the adhesive coating is applied. This preliminary integration of marking elements into the base material eliminates subsequent manufacturing steps and ensures the markings are permanently embedded in the tape structure.

AI summary
The invention relates to an adhesive tape, in particular winding tape for bandaging elongated objects, such as cable bundles in automobiles for example. The adhesive tape has a fabric support (1, 2), additionally an adhesive coating (3) which is applied onto one side or both sides of the fabric support (1, 2), and at least one marking thread (4, 5) which is introduced into the fabric support. According to the invention, the marking thread (4, 5) is a warp and/or weft thread (4, 5) which is incorporated into the fabric support (1, 2) during the production process.
