Bale wrappers machine


The bale wrappers machine SIPMA OS 7535 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. The bale wrapping machine is distinguished by advanced hydraulic system, which is extended by hydraulic adjustable shaft. The advantage of wrapping process is the economy, which allows to save working time for 12h/1000 bales and to reduce the oil demand by 110l/1000 bales.

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.

Advanced hydraulic unit causes lower resistance of the hydraulic system and provides greater control possibilities by setting the speed of all controller functions.

Hydraulic system with  Load-Sensing function affects smaller fuel consumption and grows the liveliness of tractor hydraulic pump.

Improvement the work culture of the hydraulic system through the double reduction of average work pressure and the reduction of power consumption.

Hydraulic 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

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.

The sensor on the loading arm ensures automaticly wrapping start process.

The brake of the motor makes impossible to move the table during the drive.

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.

Controlling the state of oil filter pollution signals a necessity of its change when admissible state of pollution will be overdraft.

An additional sensor of foil stops the bale wrapping process in case of foil breaks or finishes.

Large LCD graphic display ensures in easy and intuitive way to put the work parameters and shows the  state of wrapping machines parameters.

Programming the rotating speed of lifting and lowering the loading arm and the table.

Smooth control of the rotating speed of the table during work enables the adapting speed to the weight of the bale, also during bale wrapping process.

An electronic control enables setting price for wrapping one bale for a given filed and displaying informations from whole the season. 

Functionalities of an electronic control:

  • large LCD graphic display showing the actual parameters of work,
  • manual or fully automatic operation of the machine,
  • monitoring of the ongoing process of wrapping,
  • counting the number of wrapped bales,
  • measuring the time of operation [h] with the accuracy of 1 minute,
  • counting the achieved performance [bales/h],
  • measuring the volume of work on five independent fields - independent calculation of the number of wrapped bales, working time and achieved performance,
  • setting price for wrapping one bale for a given filed,
  • programming the number of film layers (depending on the kind of film used), when reached, the machine passages automatically to next work stage,
  • smooth control of the rotating speed of the table during work,
  • programming the speed of lifting and lowering the loading arm,
  • controlling the foil feeding - an additional sensor of foil stops the bale wrapping process in case of foil breaks or finishes,
  • controlling the state of oil filter pollution,
  • 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 service,
  • displaying the sum of wrapped bales since installing the board computer on the wrappers machine,  
  • displaying on the screen information concerning work in the whole current season - summing up values of data from all fields, where the bale wrapper worked (number of bales wrapped throughout the season, total working time in a season, efficiency in a season).
