Textile Conveyor Belt System with Pressure Roller for Crease-Free Web Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conveyor systems for textile plants inadequately support thin and sticky material webs, leading to creases and sticking issues, which impairs manufacturing accuracy and reliability.
Innovation Solution
A conveyor system with peripherally guided parallel conveyor belts and a pivotally mounted pressure roller that securely presses the material web onto the belts, combined with a scraper plate for reliable detachment, ensures crease-free and reliable transfer, even during extended downtimes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conveyor system with rollers is used to transfer the material web, then the operating forces applied by a user are kept low, but the material web is not adequately supported leading to crease formation and sticking to rollers
Solution Approach 1:
The patent introduces conveyor belts as an intermediary element between the rollers and the material web. The conveyor belts provide continuous support across the entire width of the material web, preventing creases while the rollers provide the driving force. This mediator resolves the contradiction by distributing the support function across a larger area while maintaining ease of operation.
Solution Approach 2:
The patent transitions from point-contact support (rollers) to surface-contact support (conveyor belts). By adding the dimension of continuous surface contact across the entire width of the material web, the system maintains ease of operation while eliminating crease formation that occurs with discrete roller support.
2Ease of operation
If the material web is supported by rollers, then handling is simplified, but the sticky material web sticks to the rollers especially after lengthy downtime periods
Solution Approach 1:
The conveyor belts serve as an intermediary between the rollers and the sticky material web. The belts provide a continuous support surface that reduces direct contact points, minimizing sticking opportunities. After downtime, the material web can be detached from the belts more easily than from rollers, improving reliability.
Solution Approach 2:
The patent changes the contact parameter from discrete roller surfaces to continuous conveyor belt surfaces. This parameter change reduces the frequency and intensity of sticking events by distributing contact across a larger area, making detachment after downtime more reliable while maintaining ease of handling.
3Device complexity
If conventional roller conveyors are used, then the structure is simple, but the thin and sticky material web sags between components and cannot be supported over greater distances
Solution Approach 1:
The patent extends the support from discrete roller locations to a continuous surface that spans greater distances between system components. The conveyor belts create a supportive dimension that bridges larger gaps without requiring additional intermediate rollers, maintaining structural simplicity while increasing the effective support distance.
4Ease of operation
If the material web is manually pulled from the unwinding station, then the process is simple, but the large width and stickiness make handling complicated
Solution Approach 1:
The conveyor belts act as an intermediary that takes over the support function from manual handling. The belts provide continuous support across the entire width of the large material web, making the transition from manual to automated handling easier while the added conveyor system complexity is justified by the significant improvement in handling ease.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides secure and crease-free support and transfer of the material web over its entire width, minimizing wrinkles and preventing sticking, ensuring reliable operation and easy handling during both normal and extended downtime periods.
Implementation Method 1
the material web can be pressed onto the conveyor belts in the region of the beginning of the conveying process via the pressure roller, so that it adheres securely to the conveyor belts

AI summary
The invention relates to a conveying system (1) for a textile plant for transferring the beginning (28) of a material web (29), in particular a sticky cord material web with textile and/or steel wires, from one plant component (2) to an adjacent plant component (3). The invention further relates to a corresponding textile plant. To ensure reliable transfer of the beginning and thus safe commissioning of the textile plant, the conveying system (1) comprises at least one conveyor belt (4), in particular several conveyor belts (4) arranged parallel to one another, running circumferentially between a conveying beginning (5) and a conveying end (6), and a pivotably mounted pressure roller (16), wherein the material web (29) can be pressed against the conveyor belt (4) or conveyor belts (4) at the conveying beginning (5) by the pressure roller (16).
