DEVICE FOR CONVEYING A TUBULAR FILM

摘要

The invention relates to a device (24) for conveying and cooling a tubular film (6) that was extruded shortly before. Said device comprises a pair of rolls, through the roll slit of which the tubular film (H16) runs into a cooling area, and a second pair of rolls (H17) through the roll slit of which the tubular film (6) leaves the cooling area. The tubular film (6) is adapted to dissipate heat into the environment between the first and second pair of rolls. The device is characterized in that the length of the path (26) which the film (6) covers between the first roll pair and the second roll pair can be varied.
