The KUHN square bale turntable wrappers are equipped with two pairs of steel rollers, with a ribbed profile. This design creates a deep and stable cradle for the bale, ensuring maximum bale traction, even bale rotation and proper film overlap, whatever the bale size. Two large bale support rollers provide additional stability and guidance. Round bales can also be wrapped with these wrappers.
The standard pre-stretchers, which hold a 750 mm roll of film, are made of aluminum to avoid tack build-up. Both outer ends of the aluminum rollers are cone-shaped to maintain the optimum width of the film and reduce the risk of film 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.
Once the desired number of film layers have been applied, the film is then held firmly and cut. A hydraulic, high-grip film cutter allows you to adjust the cutting moment 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.
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 the loading arm. The bale can be dropped on the go for maximum output.
Two different control systems are available depending on the 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 SW 1614 Computer controlled version (C) with integrated patented AUTOLOAD function offers increased overall efficiency and loading and wrapping capacity. The automatically controlled computer system is standard equipped with automatic stop at the end of film or film break and play/pause function. The RF remote control with high distance safety control is optional.
The SW 1614 C can carry a second bale in the loading arm during wrapping. The AUTOLOAD function offers increased overall loading, wrapping capacity and efficiency. The patented AUTOLOAD function 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. Picking up a second bale with the loading arm, during the wrapping process for transport, is fully automated.
