Abstract
The device for the opening and mixing of fiber bales contains a bale opening device capable of being lowered on a bale suspended from a bridge-like machine frame which is fashioned in the form of a portal and is capable of travelling along a guide rail, said bale opening device being equipped with a conveying device. A bale opening roll or plucker roll (6) is provided as the bale opening device, its axis of rotation being perpendicular to the direction of movement of the machine frame and its working width being at least 75% of the total width of the machine frame. A suction channel (9) fixedly installed above the bales (B) serves as the conveying device for the fiber material taken from the bales (B). The device is of simple construction and has a usable opening width essentially equal to its overall width and makes it possible to achieve good fiber mixing.
