Abstract (en)
[origin: GB2222606A] In an opening device for opening compressed fibre bales (1), for example cotton and rayon staple bales and the like, high-speed opener rollers (5, 6) containing opener discs or needles are provided and engage with a grid (3, 4) the grid bars of which lie between the opener discs, for example toothed discs, or needles, the movable opening device and the fixed fibre bales (1) touching one another, and the teeth of the opener discs, or the needles, cutting into the fibre bales from above. <??>In order to make possible a higher output and more uniform taking-off, adjusting means for the vertical displacement of the opener rollers (5, 6) relative to one another and/or the grids 3, 4 relative to one another are provided and on the forward stroke and the return stroke during the taking-off operation the opener discs may cut into the fibre bale (1) to different depths. Pressing rollers 8a, 8b may also be adjustable relative to one another. The rollers and grids may have individual or common adjustment means. Adjustments between rollers may be controlled by detecting electric current consumption. <IMAGE>
