Abstract
A machine for cleaning textile fibres includes a horizontal rotating roller with beater elements and bar grates on the underside of the roller. Delivery air transports the textile fibres in the form of flocks through an inlet which is arranged above the upper side and at one end of the roller. An outlet for the air transporting the fibres is located above the upper side and at the other end of the roller. Between the inlet and the outlet at least three, preferably five transfer chambers are located over the upper side of the roller, each of which lead the air stream passing around the roller axis further in the axial direction of the axis by about the width in the axial direction of the chamber. The transfer chambers are defined by four, preferably six deflectors inclined by an ascending angle with respect to the axis of the roller. The combination of the number of the transfer chambers, the specified ascending angle and the width of the chambers provides an arrangement which can prevent the collection of quantities of fibre and fibre lumps in the transfer chambers.
