Abstract
The opening device for opening pressed fiber bales, e.g. cotton bales or the like comprises opening rollers containing opening disks or needles to coact with a grate. If the opening device and the fiber bales contact each other in movement, the teeth of the opening disks or the like engage the fiber bales. To this effect, the grate rods (22,39,43) comprise an offset portion (32,40,43) extending transversely to the direction of travel (5) of the opening device (1), at least one opening disk (28;29) being arranged ahead of and/or behind the offset portion. Thus, an equalizing effect is achieved for the removal of flocks from the fiber bales.
Claims10
In a fiber bale opening device for opening pressed fiber bales such as cotton and staple fiber bales having an opening device housing in which opening rollers having opening disks with teeth or needles are provided to cooperate with a grate whose grate rods are situated between the opening disks, said opening device housing and the fiber bales moving relatively by each other in contact with the teeth or needles of the opening disks engaging the fiber bales;
- wherein the improvement comprises:
- said grate rods including a laterally inclined offset portion extending in transverse direction to the direction of movement of the opening device housing;
- and at least one opening disk being mounted ahead of such offset portion and at least one other opening disk being mounted behind each said offset portion in a manner that ridges of fiber created by said opening device are evened out by said opening disks upon movement of said opening device housing in opposite directions relative to said bales.
