PROBLEM TO BE SOLVED: To provide a improved technology of a double apron type drawframe for a spinning machinery, which drawframe is connected to the outlet roller pair of a main drafting zone and has a fiber bundling zone followed by a feed roller pair. SOLUTION: The double apron type drawframe for a spinning machinery has a fiber bundling zone connected to the outlet roller pair of the main drafting field and followed by the delivery roller pair, a pneumatic compression device between the output roller pair and the feed roller pair, which compression device has a perforated belt and a suction device, extends on the opposite side of the belt to the fiber sliver side and sucks air through the fiber sliver, wherein the belt for the double apron type drawframe is produced as a belt having perforated holes for avoiding dust accumulation and fiber hooking.
