Continuous Wrapping Web With Transverse Tape Assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wrapping technologies require assembly of discrete wrapping portions, which is inefficient and costly, as they need to be fabricated into a continuous web, whereas a continuous wrapping web assembly would simplify the process and reduce manufacturing costs.
Innovation Solution
A wrapping web assembly comprising a substantially continuous web with elongate tape assemblies, where an adhesive tape portion is adhered to one surface and a double-sided adhesive tape portion is releasably adhered to the other surface, allowing the web to be spooled and easily applied to items, such as cotton bales, with the tape assemblies spaced transversely along the web.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If discrete wrapping portions are assembled into a continuous web, then the wrapping material can be applied continuously, but the manufacturing process becomes complex and costly
Solution Approach 1:
The wrapping material is divided into discrete wrapping portions with adhesive ends that can be independently applied. Each portion has a first end with adhesive for bonding to the item and a second end with a release mechanism, allowing sequential application without requiring complex assembly of multiple components into a continuous web.
Solution Approach 2:
Adhesive is applied to the wrapping portions in advance during manufacturing, so that when the portions are separated at the desired point during wrapping, the adhesive is already exposed and ready to bond immediately to the item being wrapped, eliminating the need for complex real-time assembly mechanisms.
2Ease of manufacture
If discrete wrapping portions are used, then the wrapping material can be easily manufactured and stored, but assembly into a continuous web is required which increases manufacturing costs
Solution Approach 1:
The wrapping material is manufactured as separate discrete portions rather than as a continuous web requiring assembly. Each portion is independently produced with predetermined adhesive characteristics, simplifying the manufacturing process and eliminating the need for complex web assembly systems while maintaining ease of storage and handling.
Solution Approach 2:
The discrete wrapping portions are designed to be self-contained with pre-applied adhesive and release mechanisms, allowing them to function independently without requiring external assembly systems. The portions can be directly applied to items or stored individually, eliminating the need for complex web assembly infrastructure.
3Productivity
If a continuous web with discrete portions is assembled, then wrapping can proceed efficiently, but the manufacturing process becomes inefficient and costly
Solution Approach 1:
Adhesive is pre-applied to the wrapping portions during manufacturing, and the portions are designed with predetermined separation points. This allows the wrapping portions to be ready for immediate use without requiring complex real-time assembly during the wrapping cycle, maintaining efficiency while simplifying manufacturing.
Solution Approach 2:
The wrapping material is provided as discrete portions that can be independently handled and applied, eliminating the need to manufacture and assemble complex continuous webs with integrated adhesive systems. Each portion is self-contained and ready for application, improving both manufacturing efficiency and wrapping cycle efficiency.

Function Achieved in This Case
This solution eliminates the need for assembling discrete portions, reducing manufacturing costs and enhancing the reliability of the wrapping process by allowing a continuous web to be used directly in field baling and other applications, improving efficiency and ease of deployment.
Implementation Method 1
an adhesive tape portion adhered to one surface of the web
Implementation Method 2
a double sided adhesive tape portion releasably adhered to the release surface and adapted to adhere to the other surface of the web

AI summary
There is provided a wrapping web (11) having transverse tape assemblies (12) released from a double sided release film (13) and cut to length. The tape assemblies (12) comprise a double sided adhesive tape portion (14) adhered to the baling web (11) and an adhesive tape laminate portion (15) having a release surface overlying the double sided adhesive tape portion (14). The exposed adhesive layer (17) of the adhesive tape (15) permanently adheres to the back surface (24) of the web (11) as it is rolled up. The wrapping web assembly (10) is deployed by unwinding from an accumulator spool into a baling assembly. As the web (11) unspools from the accumulator spool, peel forces are applied to the tape assembly (12) causing separation of the adhesive (14) and double sided adhesive (15) tape portions. This presents an exposed adhesive layer (20) whereby the web (11) can be closed over itself to close the wrapping of a product such as cotton.
