Blown film take-off unit
Efficient downstream processing of extruded film hoses
In blown film extrusion, you optimize your production conditions through the wide range of adjustment options of the blown film and take-off unit:
Adjust the tube diameter, flattened film width, film thickness and film diameter flexibly and reproducibly.
Check the so-called “frost limit” (the transition from the plastic to the solid state) by means of an adjustable annular gap of the film blowing head.
Support air and adjustable haul-off speed ensure optimum conditions for haul-off of the material.
A user-friendly touchscreen allows you to adjust the working height, winding torque and cooling air conveniently and precisely.
Extend optional functions and setting options as required.
The plastic polymer exits the extruder via a ring die. The material flows out in the shape of a bubble.
The diameter of the formed bubble can be adjusted by the amount of inflation air supplied.
Through the film width control the bubble is guided upwards.
Subsequently, the material is flattened by collapsing frames and taken off by nip rolls.
The film is guided over the pulley and the guide rollers to the winder, which produces the finished film rolls.
