Rewinder description In line slitting

In a blown film extruder PE granulates (or other polymer) are melted in an extruder
and pushed through a circular die extruding a tube of molten polymer.
Tube is then inflated to multiples of its initial diameter and cooled to form a thin film.
Bobble is later collapsed and re-winded.
