The KUHN round bale turntable wrappers are equipped with two rollers and four wide, spaced belts. This design provides a deep and stable cradle for the bale on the wrapping turntable. The two large bale support rollers provide more stability and guidance. The four belts provide maximum traction and even rotation of the bale. Even bale rotation is vital to ensure the optimal film overlap for conservation and crop quality during storage.
The standard pre-stretchers, which hold a 750 mm roll, are made of aluminum to avoid tack build-up 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 tearing. 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. An optional 60% pre-stretcher gear kit can be installed to change the standard pre-stretch to 60% to adapt to difficult wrapping conditions.
Besides a standard single stretch application, KUHN offers the unique e-TWIN system for excellent, cost efficient, fast wrapping. The e-TWIN technology enables wrapping via a combined pre-stretcher design with unique film distribution to save 50% on wrapping time and further film savings. The conical pre-stretch rollers have been positioned in such a way that the two 750 mm film wraps with 2/3 overlap are glued together, providing a double layer before they leave the pre-stretcher unit. Optional on selected wrappers is the auto film layer correct kit. The correct kit detects an empty or torn film roll and adjusts the required amount of table rotations to cover the bale with the required amount of layers accordingly.
Unique advantages of e-TWIN:
Once the desired number of film layers have been applied, the film is held firmly and cut. The well-known “scissor-type” cutters hold and cut the film. Due to its design, the film is caught across the full width. The film is held with a clamp, stretched into one solid string, and then cut before the bale is unloaded. The clamp firmly holds the film ready for the next bale.
The KUHN trailed wrappers feature a unique low-profile design ideal for stability when loading, wrapping or unloading a bale. The rear axle position results in a low table height eliminating the need for an (active) fall dampener. There is constant weight transfer to the tractor that prevents up-and-down movements of the drawbar and prevents tractor wheel slippage when driving uphill with a bale on the table or loading arm. The bale can be dropped on the go for maximum output!
Two different control systems are available depending on model and driver preferences:
The manual version (M) is controlled with 3 cable levers and comes as standard with the KBC 30 bale-and-wrap counter and autostop. The bale-and-wrap counter counts the film layers and total number of wrapped bales. The autostop function will automatically stop the wrapping table once the total number of film layers have been applied. This transforms a manually controlled wrapper into a semi-automatically controlled wrapper.
The computer-controlled version (C) on the RW 1410 uses a terminal that provides all the information and possibilities for automatic operation of the entire wrapping process. As standard there is automatic stop at the end of film or film tear.
The enhanced RW 1610 computer-controlled version (C), with integrated patented AUTOLOAD function, has increased overall efficiency and loading and wrapping capacity. The RF remote control with high distance safety control is optional.
The enhanced RW 1610 computer-controlled version (C) can load and carry a second bale in the loading arm during wrapping. Thanks to the integrated patented* AUTOLOAD function, the wrapper has an increased loading and wrapping capacity. It enables the operator to fully concentrate on the driving process, while the wrapping process is automatically started once the bale has been detected on the loading arm. Even picking up a second bale with the loading arm for transport, during the wrapping process, is fully automated.
