Bale Wrapping Segments With Perforated Substrate And Sealing Accessory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bale wrapping materials often become tangled with harvesting machinery due to excessive adhesive and separation forces, leading to uneven wrapping and exposure of bales to elements during the simultaneous harvesting and wrapping process.
Innovation Solution
A continuous wrapping material is formed into separable segments with a core, using a substrate with periodic perforations or weakening lines to facilitate easy separation, and a sealing accessory with a limited number of adhesives to minimize sticking to machinery, allowing for efficient unwinding and adherence to the bale.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple adhesive layers are used to secure wrapping segments, then the wrapping material adheres better to the bale, but the wrapping material becomes tangled with the dispensing machinery
Solution Approach 1:
The patent removes the adhesive from the wrapping material substrate itself and places it only on the sealing accessory (tape dispenser). This extraction eliminates the source of tangling while preserving the necessary adhesion function at the sealing point.
Solution Approach 2:
Adhesive is applied locally only where needed for sealing (on the sealing accessory and tape), rather than across the entire wrapping material surface. This localized application prevents tangling with machinery while maintaining effective sealing capability.
2Strength
If elaborate folds are used to join wrapping segments, then the segments connect securely, but the material becomes prone to tangling and sticking
Solution Approach 1:
The patent eliminates elaborate folds and replaces them with a simple linear tear line. The folding function is extracted and replaced by a dedicated sealing accessory that applies tape, simplifying the joining mechanism and eliminating tangling.
Solution Approach 2:
The wrapping material is divided into discrete segments separated by tear lines, with each segment independently manageable. This segmentation allows clean separation without the complexity of folded connections that cause tangling.
3Strength
If excessive adhesive is applied to the wrapping material, then segments seal effectively, but the material sticks to harvesting machinery
Solution Approach 1:
Adhesive is extracted from the wrapping material substrate and relocated to the sealing accessory. This eliminates unnecessary adhesive contact points with machinery while preserving sealing function where required.
Solution Approach 2:
Adhesive application is localized to the sealing tape and dispenser mechanism, ensuring adhesive is present only where sealing is needed and not where it would cause harmful sticking to machinery.

AI summary
In a continuous roll of wrapping material for crops such as cotton or hay, or other objects, the individual wrapping segments are arranged so that a closing adhesive is part of a sealing accessory and otherwise protected by other structures of the sealing accessory until the point when this closing adhesive is to be exposed for securing a wrapping segment to itself, for example when encircling a subject bale harvested from a field, wherein adjacent wrapping segments separate from each other either at a point of weakness associated with perforations and the like.
