Foil Tape Punctiform Welding for Installation Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The handling of existing foil tapes during installation is challenging due to their tendency to hang and lose positioning, leading to increased installation time and costs.
Innovation Solution
A method of manufacturing a foil tape involving a membrane with a textile joined to its surface, where the textile sections are partially welded in a punctiform pattern to create a folded body that can be easily unfolded and repositioned, using ultrasonic or high-frequency welding techniques to secure the fold without compromising the adhesive layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If foil tape is provided in reel form for storage and transport, then storage and transport are facilitated, but handling during installation becomes difficult as the tape hangs and loses positioning
Solution Approach 1:
The foil tape is divided into multiple individual tapes, each with a tearable section at one end. This segmentation allows installers to separate and handle individual tapes from the reel without the entire tape hanging and losing positioning, while still maintaining the benefit of reel storage and transport.
Solution Approach 2:
A tearable section is extracted from one end of each foil tape. This extracted section enables easy separation and handling of individual tapes during installation, solving the problem of the tape hanging and losing positioning while maintaining reel storage capability.
2Ease of operation
If foil tape is folded for installation, then positioning is improved, but the folded state must be securely maintained without compromising the adhesive layer
Solution Approach 1:
The foil tape has different properties at different locations: the tearable section at one end has reduced adhesion or is adhesive-free, allowing easy folding and positioning without compromising the adhesive layer at other sections. This local differentiation enables secure folding while maintaining adhesive integrity where needed.
Solution Approach 2:
The tearable section is prepared in advance during manufacturing, allowing the tape to be easily folded and positioned during installation. This preliminary preparation of the tearable section enables convenient handling and positioning without requiring additional tools or steps during installation.
3Strength
If adhesive layer is applied to the membrane, then bonding to structural elements is enabled, but the adhesive layer becomes vulnerable during folding and handling
Solution Approach 1:
The adhesive layer is applied selectively to specific areas of the membrane rather than uniformly across the entire surface. The tearable section has reduced or no adhesive, protecting it from damage during folding and handling, while adhesive areas maintain bonding capability where needed.
Solution Approach 2:
The adhesive layer is segmented into different zones: areas with full adhesive strength for bonding to structural elements, and a tearable section with reduced or no adhesive to prevent damage during handling and folding. This segmentation protects the adhesive layer while maintaining bonding capability.

AI summary
The invention relates to a foil tape (10) for sealing joints between structural elements (30, 31) which are joined to one another, for example in house-building between masonry and a door or window jamb, wherein the foil tape (10) has a functional membrane (1), a textile (4) joined, preferably all-over, to the functional membrane (1) on a top side or an underside, and at least in certain areas an adhesive layer (2) applied in certain areas to that side of the membrane (1) which is averted from the textile (4), wherein the foil tape (10) is folded to produce a folded body (20), so that sections of the textile (4) lie on top of one another at least in certain areas, the sections of the textile (4) lying on top of one another being welded to one another partially and in particular in a punctiform pattern by supplying energy to the folded body (20).
