Apparatus for pinning a film, leaving a film die, onto a turning haul off drum

摘要

An arrangement for laying extruded film from a slit die onto a rotating take-off roll(1) has at least one electrode(4) parallel to and at a small distance from the surface of the take-off roll and one or more additional electrodes(8), at a distance from the take-off roll, fed with similar or different voltages to that applied to the first electrode(4) and creating additional electric fields to that of the latter.
