Patented, Conical Pre-Stretcher
Thirty-five years of KUHN wrapping heritage have proven these pre-stretchers in various conditions around the world. The standard pre-stretchers, which each hold a 30” (750 mm) roll, are made of aluminum to avoid build-up of tack from the film. Both outer ends of the aluminum rollers are cone-shaped to maintain the optimum width of the film and reduce the risk of film tear on the edges. The special ribbed profile of the aluminum rollers keeps air and water away from the film. The location of the pre-stretchers makes it very easy to change the film rolls. The standard pre-stretch of 70% is reached by a low-maintenance and low-noise gear transmission.
