The twin-satellite design ensures high-speed wrapping. 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. The special ribbed profile of the aluminum rollers keeps air and water away from the film. The location of the pre-stretchers makes it easy to change the film rolls. The standard pre-stretch of 60% is reached by a low-maintenance and low-noise gear transmission.
The positioning of the shorter top rollers allow the film roll holders to be positioned as low as possible. As a result, the film is wrapped closer to the center of the bale with less wrinkling, ensuring an optimum oxygen barrier for excellent silage quality.
Once the desired number of film layers has been applied, the film is then held firmly and cut by two “scissor-type” film cutters. The film is held with a clamp, gathered into one solid rope and then cut before the bale is unloaded. The clamp firmly holds the film ready for the next bale.
