Abstract

A textile machine apparatus for handling tubes having remaining yarn thereon includes a branch path for supporting tube support members, which individually support tubes thereon, for travel to and from the discharge assembly of a textile winding machine. The tube handling apparatus also includes a sensor disposed along the discharge transport path of the tube support members from the winding stations of the textile winding machine for discriminating among tubes having no yarn thereon and tubes having remaining yarn thereon. A guide member is operatively connected to the discriminating sensor for guiding the tube support members supporting tubes having remaining yarn thereon onto the branch path for transport therealong to a tube stripping device, which strips the tubes of the remaining yarn. The stripped tubes are then returned to the discharge transport path at a location upstream of the discriminating sensor. In one aspect of the invention, the discriminating sensor discriminates among tubes having less than a predetermined minimum amount of yarn thereon, tubes having more than a predetermined minimum amount of yarn thereon, and tubes having no yarn thereon.
