Abstract
A carding machine casing (1) is connected with a suction device (15) for preventing uncontrolled release of fibers and dust into the environment adjacent the machine, and the casing is provided with large suction openings (9, 10) having a combined area of not less than 0.5 m.sup.2 for admitting conveying air to the interior of the casing. The air is sucked in through the large openings at a substantially lower flow speed so that a considerably lower proportion of the airborne particles and fibrous particles occurring in a spinning mill are sucked into the suction device (15). In many cases it is no longer necessary to provide for precise sealing of the casing (1), and it is sometimes feasible to omit the use of a filter cloth over the suction openings (9, 10) or to simplify the maintenance (e.g., cleaning) of the filter.
