<P>PROBLEM TO BE SOLVED: To improve transmittance of suction air in a filter structure to reduce reduction in suction pressure by a blower, thereby improving recovery efficiency of fiber dusts of a fiber dust-recovering device. <P>SOLUTION: A fiber dust-recovering device of a fiber machine comprises: a negative pressure supply source 4; a suction duct 3 connected to the negative pressure supply source 4; and a filter structure disposed between the negative pressure supply source 4 and the suction duct 3. The filter structure includes: a filter base 30 covering a filter opening 33; and a filter element 31 covering the outer surface of the filter base 30. The filter base 30 is made of punching metal having a honeycomb structure comprising: one group of ventilation holes 35 having a regular hexagonal shape; and partitioning ribs 36 partitioning the adjacent ventilation holes 35. <P>COPYRIGHT: (C)2013,JPO&INPIT |
