Abstract: The present invention relates to a prestretched polyethylene film having a longitudinal stretch ratio of from about 1:2 to about 1:4 and having a longitudinal elongation capability of at least 170%, said elongation capability comprising an elastic component. The invention also relates to a method for producing said film and to a method of wrapping compressed bulk material such as a round bale using said film, the method comprising further stretching the prestretched film and applying the film around the compressed bulk material in direct contact therewith. The film according to the invention may be used as a net replacement film and allows increasing the efficiency and the economics in the baling process by allowing faster baling, use of a lesser amount of wrapping film and/or improved protection of the product.

Abstract: A forming and wrapping unit and method for forming material into a continuous bar and wrapping the material. The unit including a forming chamber for forming material into a continuous bar, a sheet wrapping device for wrapping the continuous bar, and a controller operating on the sheet wrapping device. The sheet wrapping device and the controller are adapted to be operable independently of a rate of feeding bulk material into the forming chamber. The method includes feeding material to a wrapping position while forming the material, wrapping a sheet around the material such that the sheet at least partly overlaps a previously wrapped portion of the sheet, and transferring the wrapped material from the wrapping position to a storage ready position. The feeding of the material to a wrapping position and wrapping a sheet around the material are separately operable.

Abstract: The invention provides a forming and wrapping unit (2) for forming material into a continuous bar (20) and wrapping said material the unit comprising: a forming chamber (6) for forming material into a continuous bar; sheet wrapping means (4) for wrapping said continuous bar; and control means operating on said sheet wrapping means, wherein said sheet wrapping means and said control means are adapted to be operable independently of a rate of feeding bulk material into the forming chamber. The invention also relates to a method for forming and wrapping material into a continuous bar, comprising feeding said material to a wrapping position while forming said material; wrapping sheet around said material such that said sheet at least partly overlaps a previously wrapped round of sheet; and transferring the wrapped material from said wrapping position to a storage ready position. The step of feeding the material to a wrapping position and said step of wrapping sheet around the material are separately operable.

Abstract: A method for installing a stator winding in a stator core. A winding turn is formed by drawing a cable portion from a cable reel and inserting it into two winding slots. Each winding turn that is jointlessly connected to first winding turn and has the same winding direction as the first turn is formed by making this winding turn include a cable section corresponding to a turn on the reel that has been lifted off the reel by lateral movement over a gable of the reel. To form each winding turn that is jointlessly connected to the first winding turn and has a second winding direction opposite the winding direction of the first turn, the cable portion forming this winding turn is made to include a section corresponding to a turn on the reel that has been lifted off the reel by lateral movement over the other gable.

Abstract: The invention relates to a method for installing a stator winding in a stator core (5), the stator winding being formed of at least one cable (1), which is flexible and comprises at least one electric conductor (50) with an envelope (51) capable to confine the electric field generated around the conductor. When a winding turn is to be formed, a cable portion is drawn out from the cable reel and inserted in its cross-direction into two winding slots. For the formation of each winding turn (10) that is jointlessly connected to first winding turn (10) that is jointlessly connected to a first winding turn (7) and has the same winding direction as the first winding turn, the cable portion forming this winding turn is made to include a cable section (13) corresponding to a cable turn on the cable reel that has been lifted off from the cable reel by way of a lateral movement over one (15a) of the gables of the cable reel.
