Trash elimination apparatuses for fiber cleaning aggregates

Abstract

In a fiber processing machine with a separating edge in which fibers as well as air are guided in a substantially predetermined transporting direction past the edge, trash particles are selectively removed from the fiber/air stream with the help of the edge. The adjustment of a separating element, in particular, the setting of the angular position of a separating surface and/or the penetration depth upstream from the separating surface is linked with an adaptation of the width of the eliminating gap. Also, at least one measure can be taken for eliminating, as far as possible, a pressure drop and/or air turbulences downstream (in the transporting direction) from the edge. Downstream from the edge, a flow pattern as laminar as possible is generated or maintained, respectively.
