Bale wrappers machine


The bale wrappers machine SIPMA OS 7531 MAJA is fully automated self-loading machine, attached to the tractor. Full automation of the process is provided by an advanced control system which allows pre-programming a wrapping cycle.

Technological system ‘front-back’ allows for work in the same direction as the direction of the press work (along a field), ensures fast loading of bales, wrapping with foil during the drive until the next bale, high efficiency and coupling the bale wrappers machine with the round baler, ensuring simultaneous rolling and wrapping bale during one way.

Adjustable shaft in the positions in work and transport effectively allows for collecting bales and transporting the machine over access roads including public ones to the field.

Universal film dispenser allows the use of 0.5 and 0.75m wide films.

Aluminum, milled film dispenser rollers provide the initial film stretching and appropriate adhesion during the wrapping process.

Hydraulic film catcher-cutter works automatically after each bale wrapping process, provides a considerable acceleration of the wrapping process and its efficiency.

Bale elevator allows for putting bales on their bottom or rolling them on their side surface into the field and protects the wrapped bale from possible damage during unloading.

Wide tyres provide the opportunity to work on wetlands and peat fields.

Functionalities of an electronic control:

  • manual, automatic or semi-automatic operation of the machine,
  • monitoring of the ongoing process of winding (number of wraps counter),
  • counting the number of wrapped bales,
  • measuring the time of operation [h] with the accuracy of 1 minute,
  • counting the achieved performance [ha/h],
  • measuring the volume of work on three independent fields - calculation of the number of wrapped bales, working time and achieved performance,
  • programming the number of film layers (depending of foil width), when reached, the machine passages automatically to next work stage,
  • setting the machine automatically for transport,
  • displaying the status of reed sensors (assessing operating efficiency or lack), thanks to which we are able to change a defective sensor without calling the sernice,
  • displaying the sum of wrapped bales since installing the board computer on the wrappers machine.
