Web width 1800 -2000 mm. Width of rolls of finished products from 125 mm. The structure of the produced film is A/B/C, the ratio of layers is 16/68/16.
The composition of the line: three extruders are included, each of which works on one layer of film. Three Doteco dispensers are installed on each of the extruders, which allows mixing up to three components in each layer. The extruders are equipped with heating elements and cooling fans to maintain the set temperature.
The line also includes:
fitblock, where the formation of the film structure is carried out; - extrusion head with thermal bolts installed on it; - film cooling unit consisting of two cooling drums (chill-rolls); - system of vacuum clamping of the web to the chill-roll; - devices for electrostatic clamping of edges; - an infrared system for measuring the thickness of the produced film, connected to thermal bolts mounted on the extrusion head. This allows you to automatically adjust the thickness during the production of finished products; - oscillation device; - a winder for finished products, on which the web is cut to the required size and wound into rolls; - robotic system for changing rolls.
