Development of a Lateral Control Simulation Software for Roll-to-Roll Systems
This paper presents the development and simulation results of a computer simulation software for the lateral position control of a moving web in roll-to-roll (R2R) systems. Mathematical models of the web dynamics are described first to explain the lateral motion of a moving web. Based on the models, a controller that employs the PID control method is developed, and embedded in simulation softwa...
متن کاملDynamics of roll waves
Shallow-water equations with bottom drag and viscosity are used to study the dynamics of roll waves. First, we explore the effect of bottom topography on linear stability of turbulent flow over uneven surfaces. Low-amplitude topography is found to destabilize turbulent roll waves and lower the critical Froude number required for instability. At higher amplitude, the trend reverses and topograph...
متن کاملAnode Layer Linear Ion Source for Roll-to-Roll Process from 300 mm to 1550 mm
Roll-to-roll (RTR) process requires a linear surface treatment source in various processes such as pre-treatment, etching, and deposition. For high speed and large width processes the linear source should have superior characteristics that can be applied to 100~300 m/mim process and large width treatment up to 2 m. Several linear surface treatment sources have been proposed to the RTR process. ...
متن کاملCONTINUOUS ROLL-TO-ROLL SERPENTINE DEPOSITION FOR HIGH THROUGHPUT a-Si PV MANUFACTURING
In order to further improve the economies of scale which are inherent in ECD’s continuous roil-to-roll amorphous silicon alloy solar cell manufacturing process, we have developed a concept for a serpentine web plasma CVD deposition process to maximize throughput while keeping the size of the deposition chambers small. When this technique is incorporated into a continuous rollto-roll PV manufact...
متن کاملA roll-to-roll welding process for planarized silver nanowire electrodes.
We demonstrate continuous roll-to-roll production of highly conductive silver network films on a plastic substrate via mechanical and chemical welding processes. This process included three essential steps: (i) solvent spraying, (ii) roll compression, and (iii) salt treatment and washing. The sheet resistance of the resulting AgNW film was 5 Ω sq(-1) at 92% transmittance, which was the lowest s...
