Design Parameter Analysis of a Roll-to-Roll Printing Machine
The stability of multi-input and multi-output web-tension systems is an important factor that is required for the roll-to-roll printing machines. This paper analyzes stability for design parameters of a web-tension system of a high-speed gravure printing machine. Analyzed parameters include moment of inertia of the passive dancer, viscous friction coefficient of the dancer system, distances fro...
متن کاملA Feed-forward Tension Control in Drying section of Roll to Roll e-Printing Systems
The mathematical model for tension behaviors of a moving web by Shin (Shin, 2000) is extended to the tension model considering the thermal strain due to temperature variation in a dryer of the roll to roll systems. The extended model includes the terms that take into account the effect of the change of the Young’s Modulus, the thermal coefficient, and the thermal strain on the variation of tens...
متن کاملTwo-dimensional Register Modeling and Control in Multi-layer Roll-to-roll e-Printing Systems
For the adaption of roll-to-roll printing method to the printed electronics, it is mandatory to increase the resolution of register control. A two-dimensional register was derived considering both the lateral motion and strain of a moving web, and the transverse position of a printing roll. Also, a correlation between machine directional register and cross directional register was analyzed and ...
متن کاملMIMO Tension Modelling and Control for Roll-To-Roll Converting Machines
Roll-to-roll converting machines have significant interactions in tensions and speeds among web spans. A reasonable MIMO model for web tension plays an important role for high-performance converting machines. In this paper, we derive a nonlinear MIMO web-tension model of a high-speed gravure printing machine considering span length to be time-varying instead of considering it to be fixed. Then ...
متن کاملFlexure-based Roll-to-roll Platform: A Practical Solution for Realizing Large-area Microcontact Printing
A continuous roll-to-roll microcontact printing (MCP) platform promises large-area nanoscale patterning with significantly improved throughput and a great variety of applications, e.g. precision patterning of metals, bio-molecules, colloidal nanocrystals, etc. Compared with nanoimprint lithography, MCP does not require a thermal imprinting step (which limits the speed and material choices), but...
