Abstract
An apparatus for sorting spent tubes as they are carried on an intermittently advancing conveyor with the apparatus having a tube ejecting device that reciprocates along the length of tubes during dwells in conveyor movement and has a tube contacting element that slides along clean surfaces of the tubes without causing ejection but engages any residual windings of yarn on tubes to thereby force the tubes with residual windings to move longitudinally and out off the conveyor. The tube contacting element has a base portion with resilient flat teeth projecting therefrom longitudinally with respect to the tubes and in the direction of tube ejecting movement. The base portion is a flat resilient plate from which the teeth project at an inclination toward the tube surface for resilient biasing thereagainst to facilitate engagement of residual windings thereon and resulting ejection of tubes with yarn windings while allowing clean tubes to remain on the conveyor.
