Sensitive Tension Control
“ Ultrasonic sensors monitor the roll diameter of both the unwin”d and the rewind.Deacro’s slitter rewinder equipment feature extremely sensitive tension control. Desired rewind and unwind web tensions as well as web width are entered in the touch screen (or recalled from the database recipe of files). Rewind tensions are programmable from constant tension to 100% taper. Ultrasonic sensors monitor the roll diameter of both the unwind and the rewind. A pneumatically loaded nip roller isolates web tension from the unwind to the rewind.
The sensitivity of Deacro’s slitters and flexibility of the rewind tooling, such as the Deacro roll lock differential air shafts, set Deacro apart from other manufactures. Deacro’s slitters are the industry leader for converters winding complex laminates and thin gauge webs requiring the most sensitive tension control.
Deacro’s slitter touch screen allows real-time monitoring of the rewinding process throughout the build up of the roll(s). A load cell roller is used to take incremental tension readings throughout the winding process. The data can then be compiled and output in a graph or chart format. This system provides the best feedback and confirmation for tension sensitive applications.
