Abstract
A suction and cooling system for a spinning frame having a plurality of spinning units arranged along a frame. The suction and cooling system includes a first collecting channel and an independent second collecting channel and exhaust means coupled to the first collecting channel and exhaust means coupled to the second collecting channel. The first exhaust means draw a first air stream into the first collecting channel from primarily the area around the drafting system of the spinning units. The first air stream comprises primarily reusable fibers and a filter may be provided for filtering out the reusable fibers. The second exhaust means draws an independent second air stream from primarily the area around the thread guiding device of the spinning units and from around the spindle drive means, thereby serving the dual function of collecting waste fly and cooling the spindle drive means. A second filter device may be provided in the second collecting channel for removing generally waste fiber fly material.
