Solution Overview
Problem
Existing fabric brushing machines fail to provide sufficient stretching and contact between the fabric web and brushes, leading to inadequate treatment and potential damage to the fabric.
Innovation Solution
A fabric brushing machine with rotating brushes and auxiliary rollers, along with a contrast element that presses the fabric against the brushes, ensuring effective contact and adjustable contact surface to match fabric width, enhancing the brushing effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If idle rollers are used to feed the fabric web along a zig-zag path, then the angle of winding and traction action are increased, but the stretching effect remains insufficient and the fabric web is not correctly held in contact with the brush
Solution Approach 1:
The presser roller is made movable along the fabric web width direction, allowing dynamic adjustment of its position. This enables the roller to adapt to different fabric widths and maintain optimal pressing contact, transforming a static system into a dynamic one that can respond to varying conditions and ensure consistent contact between the fabric and brush.
Solution Approach 2:
The presser roller acts as an intermediary element between the fabric web and the brush. By introducing this intermediate component, the system achieves better contact control - the roller mediates the interaction by pressing the fabric against the brush surface, ensuring reliable and consistent contact that directly addresses the previously insufficient contact consistency.
2Power
If the fabric web is not sufficiently pressed against the brush, then the brushing action is not energetic enough, but increasing pressure may cause fabric damage
Solution Approach 1:
The system allows adjustment of the presser roller's position and pressing force, enabling parameter optimization. By changing the pressing parameters dynamically, the system can achieve sufficient brushing energy when needed while avoiding excessive pressure that would cause fabric damage, thus resolving the contradiction between brushing power and fabric protection.
Solution Approach 2:
The movable presser roller enables dynamic control of pressing force distribution. Instead of applying static uniform pressure, the system can adapt the pressing force dynamically across different positions and conditions, ensuring adequate brushing energy is delivered without causing fabric damage through excessive or uneven pressure.
3Adaptability or versatility
If the contact surface between the brush and fabric is not adjustable, then the machine cannot adapt to different fabric widths, but adding adjustment mechanisms increases device complexity
Solution Approach 1:
The presser roller serves multiple functions: it presses the fabric against the brush, it can be positioned at different locations along the fabric width, and it adapts to various fabric widths. This multi-functional design achieves adaptability without proportionally increasing complexity, as the same component performs multiple roles rather than requiring separate mechanisms for each function.
Solution Approach 2:
The adjustable position of the presser roller along the fabric web width direction provides dynamic adaptability to different fabric widths. This simple dynamic adjustment mechanism allows the machine to handle various fabric sizes without complex reconfiguration systems, achieving versatility through a single movable component.

AI summary
A brushing machine for fabrics comprises a plurality of rotating brushes (108, 109, 110) for surface treatment of a web (101) of fabric. Each brush (108, 109, 110) is associated with a contrast element (1) suitable to define, in cooperation with the brush (108, 109, 110), a span through which the web (101) can pass. The contrast element (1) can operatively abut the respective brush (108, 109, 110) in order to press the web (101) against the brush (109).
