Fiber Body Manufacturing Method Preventing Web Sticking
Solution Overview
Problem
In existing fiber body manufacturing methods, the use of water with starch or PVA can cause the web to stick to pressure rollers, leading to poor transportation and potential damage.
Innovation Solution
A method involving a fiber body manufacturing apparatus with a dry accumulating section forming a web on a first transport belt, a transport section that peels off and transports the web using a second transport belt, a water-applying section that applies water without starch or dextrin to reduce adhesion, and a heating section that binds fibers with starch or dextrin to form a fiber body, ensuring the web is directly supplied to the heating section without sticking to other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If water containing starch or PVA is sprayed to the web, then fiber binding strength is improved, but the web sticks to the pressure roller causing poor transportation and potential damage
Solution Approach 1:
The web is peeled off from the first transport belt before reaching the pressure roller, and is directly supplied to the heating section. This preliminary separation action prevents the web from sticking to the pressure roller while still allowing starch or PVA to bind fibers effectively during heating
Solution Approach 2:
The patent extracts the web from the transport belt system at a specific point, removing it from the sequence that would otherwise lead to contact with the pressure roller. This extraction eliminates the sticking problem while preserving the fiber binding function
2Reliability
If the web is peeled off from the first transport belt and supplied directly to the heating section, then web sticking to pressure roller is prevented, but transportation control becomes more difficult
Solution Approach 1:
A second transport belt is introduced as an intermediary element between the first transport belt and the heating section. This mediator facilitates controlled web removal and direct supply to the heating section, maintaining operational ease while preventing sticking
3Strength
If starch or PVA is used to bind fibers, then fiber body strength is enhanced, but adhesion to transport components increases causing sticking
Solution Approach 1:
The web is separated from the transport belt before encountering pressure rollers or other transport components where sticking would occur. This timing ensures starch or PVA binds fibers during heating without causing adhesion to metal surfaces
Solution Approach 2:
The patent changes the temporal parameter of when binding occurs - fiber binding with starch or PVA is activated during the heating phase rather than during transport phases, eliminating the harmful adhesion effect while maintaining strength enhancement
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
This approach prevents web sticking to transport belts and rollers, enhances mechanical strength by forming hydrogen bonds, and reduces energy consumption while maintaining high fiber density and strength.
Implementation Method 1
a water-applying section that applies water to the web, wherein the web peeled off from the second transport belt is directly supplied to the heating section
Implementation Method 2
a heating section that heats the web to which the water is applied
Implementation Method 3
forming a fiber body by binding the fibers with the starch or dextrin
