Abstract

Abstract A device for removing tufts of fibers from a compressed bale of textile fibers comprises an opener roller with teeth on its periphery to remove the fiber flocks and convert them to the desired flocculent form. A back-stripper roller then removes the insufficiently opened flocks from the opener roller after which the opened flocks are removed from the opener roller by a stripper roller. The insufficiently opened flocks are returned to the opener roller where they are compressed by an oscillating panel against the opener roller causing the teeth on the opener roller to again take up and flocculate the insufficiently opened flocks.
