Feedback controlled tension applying system

摘要

A feedback controlled tension applying system (100) includes a corrugated fin processing device (2) that processes a fin material (1) in continuous sheet form while applying a tension to the fin material (1), a tension applying device (4) that applies the tension to the fin material (1), an encoder (6) that measures a moving length amount per predetermined time of the fin material (1), and a control device (10) that feedback-controls the tension applying device (4) based on a measurement result of the encoder (6) so that the moving length amount per predetermined time of the material (1) becomes a set value that is set in advance. <IMAGE>
