Duct for textile machine and textile machine equipped with the same

摘要

A blower duct is formed such that a cross-sectional shape cut at a plane perpendicular to a suctioning direction by a blower box (negative pressure source) is a polygon. The blower duct (20) includes a first wall surface formed to a planar shape so as to become one surface that configures the cross-sectional shape. The first wall surface is formed with a first air inflow hole (31) for supplying suction force to each winding unit of an automatic winder (10). An opposing surface wall facing the first air inflow hole (31) is formed inclined with respect to the first wall surface. A cyclone flow generates in the blower duct (20) by the first air inflow hole (31) and the suction force of the blower box.
