Sealing Tape Foam Strip Separation for Film Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The introduction of a film element into the gaps between foam strips in sealing tape production is complex due to the limited width of the cuts, making it difficult to attach sealing elements efficiently.
Innovation Solution
The method involves cutting a foam carrier into separate strips and moving them in different directions to increase the distance between them, allowing for easier attachment of a film element or adhesive tape, which is then reintroduced between the strips to form a sealing tape with enhanced airtightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cut is made in the foam carrier to create separate foam strips, then the foam strips can be separated, but the distance between them remains limited making it difficult to attach film elements
Solution Approach 1:
The foam carrier is dynamically separated into individual strips after cutting, allowing the strips to be moved apart temporarily to increase accessibility for film element attachment. This dynamic separation enables operators to access and attach film elements to each foam strip independently, then the strips are recombined into the final sealing tape product.
2Ease of operation
If the foam carrier strips are kept close together after cutting, then the structure remains compact, but the accessibility of surfaces for sealing element attachment is reduced
Solution Approach 1:
The foam carrier is segmented into individual foam strips through cutting, and these strips are temporarily separated to increase surface accessibility. This segmentation allows each strip to be independently processed with film elements attached to its surfaces, improving operational ease without significantly complicating the overall production process.

AI summary
The invention relates to a method and a device for producing a sealing tape, wherein a foam carrier is transported in a predetermined transport direction (T) and a cut is made in this foam carrier extending in this transport direction, and at least two completely separate foam carrier strips (10a, 10b) are produced by this cut, wherein a distance between this first foam carrier strip (10a) and the second foam carrier strip (10b) is increased by transporting at least one of these two foam carrier strips at least temporarily in a different direction (Y) than the other foam carrier strip. The invention further relates to a sealing tape with a base carrier.
