STRETCHING MACHINE
FOR PLASTIC FILM

After controlled cooling, the primary film passes through the longitudinal stretching machine, where the film is stretched in machine
direction by several groups of driven rollers, which are running at
different speeds.
In the following transverse stretching machine, the film is gripped
by clips on both sides and stretched in width with heat applied.
Cross loads up to 3,500 N per clip can occur. Material and bearings have to withstand temperatures in the range of 100 to 250°C
at production speeds between 100 and 500m/min according to
output and film thickness.
