Baler Wrap Material with Catch Recesses for Reliable Gripping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wrapping materials for baling presses often fail to grip properly at the beginning of the wrapping process, leading to incomplete wrapping or blockages, especially under unfavorable harvesting conditions.
Innovation Solution
Incorporating catch-like recesses and predetermined tear areas in the wrapping material, along with a feed device and fold areas, to improve gripping and ensure consistent wrapping material supply, preventing blockages and ensuring equal wrapping material distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional wrapping material is used without catch structures, then the material can be supplied continuously, but the material is not gripped properly by the bale at the beginning of wrapping, leading to blockages and incomplete wrapping
Solution Approach 1:
The wrapping material is equipped with catch structures (recesses or protrusions) at specific locations to interact with the bale material. These localized features provide enhanced gripping capability at critical points without requiring the entire material structure to be complex, thus improving reliability while maintaining reasonable structural simplicity.
Solution Approach 2:
The catch structures act as intermediary elements between the wrapping material and the bale material. They facilitate the gripping interaction by providing specific engagement points that allow the bale to effectively grasp the wrapping material, preventing slippage and blockages during the wrapping process.
2Ease of operation
If wrapping material is supplied without predetermined tear areas, then continuous wrapping is possible, but sections cannot be easily separated without additional separating devices or knives
Solution Approach 1:
The wrapping material is divided into discrete sections by providing predetermined tear areas between them. This segmentation allows each section to be easily separated from adjacent sections through simple tearing actions, eliminating the need for additional separating devices or knives and simplifying the overall system while improving operational ease.
3Reliability
If the wrapping material width is not wider than the bale chamber, then the material can be handled more simply, but the bale cannot be completely wrapped or the wrapping material cannot be properly positioned
Solution Approach 1:
The wrapping material is designed with a width that exceeds the bale chamber dimensions, providing additional material in the lateral dimension. This extra width allows the material to be properly positioned and secured around the bale, ensuring complete wrapping coverage. The catch structures further assist in positioning the material correctly within the chamber.

AI summary
A covering material (38) for a baler (10), in particular an agricultural baler for forming especially round cylindrical bales (12), for covering preferably at least substantially the outer surface (43) of a bale (12), is proposed, wherein the covering material (42) has at least one driver (78).
