Univex
The Univex can take off, cool, and wind up flat films up to a max. film speed of 30 m/min.
The Univex can be controlled manually or through the PC (via CAN bus).
Liquid temperature conditioning of the nip rolls positively influences e.g. crystallization processes.

 Take-Off Unit for Flat-Films |
Flat film take-off
The flat film take-off is a compact, freely movable downstream unit allowing for both horizontal and vertical film take-off. This, together with the installed heating/cooling facilities, makes the flat film take-off perfectly suited for a wide range of polymer melts.
The nip rolls have a speed advance to ensure tight film guidance. The torque-controlled winder is equipped with a traversing film guiding device for uniform and space-saving winding. Unilateral support of rolls and guide rollers provides for easy threading of the film.
The significance of this line goes, however, clearly beyond the application as a simple take-off and winding unit. The special film guidance between the two pairs of rolls enables the use of a film test line, i.e. optical film purity inspection by means of an installed Film Quality Analyzer FQA (digital line camera with PCI based image processing). In this case, an optional glass door ensures dust-free operation.
The design of the flat film take-off enables the installation of further test instruments like hazemeter, NIR systems for density or additive determination, etc.
Like all new developments of Brabender®, the flat film take-off is equipped with CANopen fieldbus technology offering manifold advantages for state-of-the-art control and data transfer.
