Bale wrapper - SIPMA OR 7532 DIANA

SIPMA OR 7532 DIANA bale wrapper is fully automated self-loading machine, tractor-trailed. Apart from conventional wrapping it allows to wrap bale in 2 extra dimensions - 3D bale wrapping. It has full automation of the whole wrapping process, which is provided by the on-board computer with the possibility of earlier programming of the work cycle parameters.

The wrapper gives choice between:
- maximum wrapping speed,
- minimal usage of film.

• SIPMA OR 7530 DIANA apart from conventional wrapping they allow to wrap bale in 2 extra dimensions - 3D bale wrapping. This effect is achieved by tilting the foil feeders. The result of this method of wrapping bales is foil savings of approx. 25%.
• Technological system „front-back" allows work in the same direction as press works. Such solution ensure fast bale loading and foil-wrapping during ride to the next bale. Coupling with press, ensuring simultaneously baling and wrapping during one ride.
• Bale elevator allows for putting away bales on the bottom , which prevents wrapped bales against damage during unloading.
• Hydraulic film catcher-cutter works automatically after each wrapping of bale, what fasten bale wrapping process and improving efficiency.
• Wrapping speed depends on chosen technique of wrapping:
  - conventional wrapping 2D - wrapping cycle last about 50 sec, and 8 spins of arms are enough to wrap whole bale. The 2D wrapping gives opportunity to save working time;
  - wrapping 3D - wrapping cycle last about 65 sec, and is realized in 2 stages: circumferential wrapping with a horizontal arrangement of foil feeders and wrapping  bottom of the bale with vertical arrangement of foil feeders. 3D wrapping is more laborious but allows to reduce consumption of  foil approx. 25%.
• Foil consumption per bale during conventional 2D wrapping requires: approx. 60 m of foil, while during 3D wrapping amount needed lowers to approx. 45 m.
• Wide tires provides the ability to work in wetlands and peat areas.
• Foil dispenser allows the use of 0.75 m wide films.
• Aluminum, knurled rolls in the foil dispenser they ensure effective stretching of the film and adequate adhesion and tightness during the packing process.
• Tray for 6 extra rolls of foil allows smooth and economic work during wrapping without unnecessary downtime.
• Adjustable hydraulic drawbar makes it easy to move machine and to transport it on access roads to the field.
• Hydraulic system with Load-Sensing  function lowers the fuel consumption.
• On-board computer capabilities:
  - manual or full automatic operation of wrapper,
  - real-time tracking wrapping process (counter of the number of wraps),
  - wrapped bales counter, device operation time measurement [h] with an accuracy of 1 minute,
  - ability to program the number of wraps (when it goes over programmed number of wraps - wrapping process stops),
  - sensor condition on display (because sensors are most exposed to mechanical damage, we have opportunity  to fast estimate efficiency and in case of drawback we can fix it by just putting a new sensor without the need to call the service),
  - big LCD screen shows actual work parameters,
  - smooth adjustment of the rotational speed of the arms during operation,
  - ability to program lifting and lowering loading device,
  - foil feeding control - additional foil sensors stops bale wrapping process in case breaking or running out of the foil,
  - oil filter contamination control,
  - displaying the sum of wrapped bales since the device were installed on the wrapper,
  ​- displaying all of the data regards to whole season work.
