Abstract
A travelling fiber tuft detaching device for removing fiber tufts from top surfaces of stationarily supported fiber bales includes two parallel-arranged detaching rollers rotatable about substantially horizontal axes spaced from one another in a travelling direction and extending transversely thereto. Each detaching roller has a plurality of detaching elements arranged in a plurality of side-by-side situated circumferential series. The detaching device further has a grate formed of a plurality of spaced grate bars extending parallel to the travelling direction. The detaching elements of each circumferential series project into spaces between respective adjoining grate bars. There is further provided a roller and/or grate setting device for adjusting a height level of the detaching rollers and/or grates relative to one another for effecting penetration of the detaching rollers into a top bale surface to different depths thereof during detaching operation.
