Abstract
An apparatus for opening and cleaning textile fiber material includes a fiber feeding device for advancing the fiber material; a first clothed roller situated downstream of the fiber feeding device and being arranged for entraining the fiber material advanced by the fiber feeding device; a second clothed roller situated downstream of the first clothed roller and being arranged for entraining fiber material after entrainment thereof by the first clothed roller; a mote knife cooperating with the first and second clothed roller; a waste removal clearance bounded by each respective mote knife; and a third clothed roller situated between the first and second clothed rollers. The first, third and second clothed rollers are arranged in series, whereby the fiber material passes from the first clothed roller to the third clothed roller and from the third clothed roller to the second clothed roller. The third clothed roller cooperates with the first clothed roller and the second clothed roller cooperates with the third clothed roller as a doffer-and-opening roller.
