  • the parallel axes of the opening rollers are aligned horizontally to one another.
  • the opening rollers reach the same depth from above into the surface of the fiber bale during removal.
  • the opening rollers have different directions of rotation, whereby the rollers move towards each other in the area of the bale surface. If the opening rolls move in one direction during processing, both opening rolls take different amounts (production) off the fiber bales, with one opening roll working in parallel and the other roller in counter-milling.
  • the invention is based on the object of creating an opening device of the type described in the introduction, which it calls avoids disadvantages, which in particular allows a higher production and a more even purchase.

  • a pneumatic pressure cylinder 16 is provided as an adjusting means, which is assigned to the removal device 2a.
  • the removal device 2a can be rotated about a rotary bearing 17 in the direction of the two parts I and K; as a result, the opening rollers 5, 6 and the grids 3 and 4 are rotated about the horizontal axis 18, so that the opening rollers 5, 6 and grids 3, 4 are displaced in the vertical direction.
  • 4a shows the opening rollers 5, 6 in the forward position (arrow B).
  • the opening rollers 5 and the grate 3 are arranged a distance z 1 higher than the opening roller 6 and the grate 4.

  • the pneumatic cylinder 20 is connected downstream of the control device 26. If the current consumption of the drive motors 21 and 22 is different, the pneumatic cylinder 20 (actuator) is automatically set such that the difference between the two electrical currents consumed goes to zero.
  • control circuit 26 is provided in connection with the input of the direction of travel of the removal member, so that the adjustment device for the pneumatic cylinder 20 (actuator) is recognized. For example, it is determined which of the opening rollers 5 or 6 works in the opposite direction; then the synchronizing opening roller emerges from the bale surface 1a and the synchronizing opening roller dips into the bale surface 1a.

  • FIGS. 7a, 7b show an embodiment in which the opening rollers 5, 6 and the pressure rollers 8a, 8b, 8c are mounted on the rotary bearing 34.
  • a pressure cylinder 32 is provided, which causes the opening rollers 5, 6 and the pressure rollers 8a, 8b, 8c to be displaced in the vertical direction via the rotation (arrows I, K) around the pivot bearing 34 (cf. FIG. 7b).
  • the housing 2 is not rotatable.
  • the openings 5, 6 and the pressure rollers 8a, 8b, 8c are arranged rotatably or displaceably within the housing 2 and independently of the housing 2.

  • an inclined surface can be generated from a horizontal upper side of the row of bales by gradually (gradually) rotating the opening roller, which is maintained during further processing. Continuous bales are pushed on the side of the row of bales facing away from the inclined surface.
  • the opening rollers are gradually (step by step) rotated in the opposite direction, so that the inclined surface merges again into the horizontal.
  • the boom 2 remains either horizontally or in a certain inclined position and only the milling device is rotated.
  • the displacement path of the boom in the height direction and the longitudinal movement of the tower can be set as a function of the predetermined oblique angle via a control device.
  • the opening rollers 5, 6, grates 3, 4 and support rollers 8a, 8b are each assigned a pneumatic cylinder 32a to 32f as setting means.

  • the control device (not shown) assigned to the pneumatic cylinders 32a to 32f permits vertical displacement in such a way that any desired processing inclination (angle ⁇ ) can be achieved.
  • the boom 2 is movably attached to the tower of the bale opener together with the opening rollers, grates and support elements.
  • the opening rollers 5, 6, grates 3, 4 and support rollers 8a, 8b are displaced relative to and independently of the boom 2.
