METHOD FOR TRANSFER SPEED CONTROL OF NON-CONTACT WEB TRANSPORT SYSTEM

摘要

PURPOSE: A transfer speed control method of a non-contact web transfer system is provided to prevent damage to a pattern or the low printing quality. CONSTITUTION: A transfer speed control method of a non-contact web transfer system is as follows: The driven tension value and the driven speed value are measured(a). The pressure of air input by a non-contact air-floating roll is measured(b). The floating height of a material is measured using the measured tension value and the air pressure in a static state, and the measured floating height is made into a graph(c).
