ABSTRACT:
The extraction arm of a fiber bale opening machine is provided with an adjustable grid made up of spaced apart grid bars between which driveable fiber removal members project to detach tufts of fiber from the bales. The depth of projection of the fiber removal members through the grid is adjustable by adjustment of the positions of the grid bars. The grid bars are mounted at their two ends on respective pivot spindles and at least one lever mechanism rotates a pivot shaft to move the pivot spindles up or down to lift or lower the grid bars. Also, the grid bars are restrained against undesired movements in the direction of their lengths by suitable stops or slots.
