Abstract
A fiber bale opener includes an upwardly open bale supporting box having a bottom, bale supporting walls together surrounding the bottom for laterally supporting the fiber bale positioned on the bottom; a raising and lowering device connected to the bottom for vertically displacing the bottom and carrier elements for coupling the bottom to the raising and lowering device. The raising and lowering device is situated externally of and horizontally adjacent the box. There is further provided an opening device arranged for a back-and-forth travel above the box to remove fiber material from a top face of the fiber bale positioned on the bottom.
Claims15
In a fiber bale opener including
- an upwardly open bale supporting box having a bottom bale supporting walls together surrounding the bottom for laterally supporting the fiber bale positioned on the bottom;
- said supporting walls being formed by opposite end walls and opposite side walls having external faces oriented away from said bottom;
- a raising and lowering device connected to the bottom for vertically displacing said bottom and
- an opening device arranged for a back-and-forth travel above the box to remove fiber material from a top face of the fiber bale positioned on the bottom;
- the improvement wherein said raising and lowering device is situated externally of and horizontally adjacent said box;
- further comprising carrier means for coupling said bottom to said raising and lowering device;
- and means for allowing pivotal motion of at least one of said walls about a horizontal axis downwardly away from said box.
