Winding technology - pneumatically actuated tension brakes, web tension open-loop and feedback control systems
|
In the section 'winding technology' you will find all the equipment necessary to control the unwinding forces, and thereby the web tension on unwinding lines of every type. These consist primarily of tension brakes, transducers, and the devices for open-loop and feedback control systems. In particular, control systems have found wide application in the processing of rolled material in sheet form such as paper, cardboard, plastic film, metal foil and textiles. If unwinding processes are to run in a fault free manner, it is necessary that the web tension remains more or less constant regardless of changes resulting from the operating conditions. The requirements, in terms of the degree to which the line tension and winding speed operating parameters must be kept constant, vary with the particular application. To satisfy these differing requirements, Ortlinghaus has available a flexible winding technology system. You will always find in the range the optimum combination of dry or wet-runnig tension brakes, transducers and pneumatic or electronic control systems to produce the unwinding control system that is precisely matched to your particular application, being both reliable and cost effective. Thanks to the modular design, a system can be extended in stages to a high level of automation including fully automatic 'flying' roll changes.
