Fast and Reliable Wrapping

Round Turntable

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 wide-spaced belts provide maximum traction and even rotation for the bale. Even bale rotation is vital to ensure the optimal film overlap to seal the bales and maintain crop quality during storage.

Conical Pre-Stretcher

The standard pre-stretchers, which 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 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%, rather than 70%, to adapt to difficult wrapping conditions.

e-Twin Technology

Besides a standard single stretch, KUHN offers the innovative e-Twin system for economical and fast wrapping. e-Twin technology enables wrapping via a unique combined pre-stretcher design with film distribution to save 50% on wrapping time and additional film savings. The conical pre-stretch rollers have been positioned in such a way that the two 30" (750 mm) film wraps with 2/3 overlap are stuck together, providing a double layer before they leave the pre-stretcher unit. Optional on some of the 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 target amount of layers using only one roll of film.

Unique Advantages of e-Twin:

// Save 50% wrapping time

// Further film saving achieved by increased pre stretch ratio

// Tighter wrapped bales seal more effectively for higher quality feed

// Extreme tear resistance

// Available on manual and computer -controlled versions

Film Cutters

Once the desired number of film layers have been applied, the film is then held firmly and cut. A spring-loaded or hydraulic high-grip film cutter holds and cuts the film automatically without the need for extra controls. The hydraulic high-grip film cutter, on the RW 1410 & RW 1610, allows you to adjust the cutting movement independent of the table tipping position, resulting in the shortest possible end string. It has a long stroke to help accommodate various bale lengths, and ensures a firm hold and a clean cut of the film in various weather conditions.

Low-Profile Chassis Design

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 on 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!

Low Table Height

The low table height on the mounted RW 1110 ensures a gentle bale discharge so there is no need for a fall dampener. The low height also allows easy replacement of the film rolls.

Manual or Computer Control

Control Systems

Two different control systems are available dependent on model, and driver preferences:

 The manual version (M) is controlled with cable levers, and comes standard with the 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 enables semi-automatic wrapping, even with manual controls.  

The computer-controlled version (C) uses a color touchscreen VT 30 to provide all the information and features of fully automatic wrapping.  

 The RW 1110 computer-controlled version (C), with standard RF remote control, can be operated from a loader while using a power pack or second tractor for the oil- and power supply. This creates a one-person operation for loading, wrapping and stacking. The C version comes standard with automatic stop at the end of film/film tear, integrated bale and wrap counter, play/pause function and 90° loading position.

The computer-controlled version (C) on the RW 1410 uses a color, touchscreen VT30 to monitor automatic operation and intuitively control the entire wrapping process. Automatic stop at the end of the film roll or film tear comes standard. The enhanced RW 1610 Computer-controlled version (C), with integrated AutoLoad function, has increased overall efficiency and loading and wrapping capacity. The RF remote is optional.

AutoLoad

The RW 1610 C can carry a second bale in the loading arm during wrapping. The AutoLoad function offers increased overall loading, wrapping capacity and efficiency. The AutoLoad function enables the operator to fully concentrate on driving, while the wrapping process is automatically started once the bale has been detected on the loading arm. Picking up a second bale for transport, during wrapping, is fully automated.
