Structured Mangle Belt Surface for Slippage-Free Laundry Entraining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing belt mangles for laundry mangling suffer from slippage issues due to old mangle belts, leading to compromised surface integrity and creases in laundry items, which affect mangling quality.
Innovation Solution
The mangle belt is designed with a structured outer surface to ensure slippage-free entrainment of laundry items, featuring a roughened surface with a higher coefficient of friction and longitudinal and transverse bracings for stability, preventing elongation and maintaining dimensional stability during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a smooth mangle belt surface is used, then the belt is easier to manufacture and has lower friction resistance, but slippage occurs between the belt and laundry items compromising surface integrity
Solution Approach 1:
The mangle belt is designed with differentiated surface properties: the outer face contacting laundry items has a roughened structure with higher friction coefficient for reliable entrainment, while the inner face remains smooth for easy cleaning and maintenance. This local quality differentiation resolves the contradiction between reliable slippage-free entrainment and ease of manufacture.
2Productivity
If the mangle belt operates for extended periods, then productivity increases, but the belt surface degrades leading to slippage and reduced mangling quality
Solution Approach 1:
The mangle belt incorporates a roughened outer surface structure that maintains its high friction coefficient and entrainment properties even after extended operational periods. This parameter change in surface topology ensures that the belt retains its slippage-free performance and reliability throughout its service life, enabling continuous high-productivity operation without degradation.
3Reliability
If a roughened belt surface is used, then friction coefficient increases improving entrainment, but the belt surface area effectively contact laundry increases leading to more creases
Solution Approach 1:
The mangle belt features a roughened structure specifically on the outer face that contacts laundry items during entrainment, while the inner face remains smooth. This localized roughness provides the necessary high friction coefficient for reliable frictional engagement and slippage-free operation, while the smooth inner face prevents additional crease formation during the mangling process.

Function Achieved in This Case
This design ensures reliable, slippage-free entrainment and effective flattening of laundry items, enhancing mangling quality by preventing creases and maintaining belt stability under load.
Implementation Method 1
the outer face of the respective mangle belt which comes into contact with the laundry items is configured so as to be rough or roughened, respectively... the outer face disposes of a coefficient of friction which is greater than the coefficient of friction of the laundry items

AI summary
Belt mangles, in which a revolvingly driven mangle belt runs along on the outside of the mangle body which is curved in a trough-like manner, convey in an entrained manner laundry items to be mangled along a smooth flattening face of the mangle body. Slippage between the mangle belt and the laundry items, which causes the quality of mangling to suffer, can occur. A mangle belt is provided with a structured outer face to bear on the laundry items to be entrained. The outer face is formed from a needled felt from highly temperature-resistant man-made fibers. On account of the structuring of the outer face of the mangle belt, a rough entrainment face or adhesion face, respectively, for the laundry items, that ensures slippage-free entrainment of the laundry items by the mangle belt while conveying the laundry items along the flattening face of the mangle body, is created.
