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.

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 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. A 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.
