Abstract
Abstract Elongated articles such as bobbin tubes are sorted automatically by providing each tube with two bands having different spacings for different article characteristics, e.g. color. The band spacings of the articles are detected automatically, e.g. electrically where the bands are conductive, by conveying the articles successively past different sorting stations, each responsive to a particular band spacing, at which removal of detected articles is effected automatically.

Process for effecting automatic sorting of bobbin tubes of different colors comprising the steps of: providing each bobbin tube with two longitudinally spaced-apart regions separated by a predetermined distance selected in accordance with the colors of the bobbin tube, the inter-region spacing being the same for all bobbin tubes of the same color; conveying the bobbin tubes singly in succession in the direction of their length on a conveyor through successive spaced-apart sorting stations equaling in number the number of different bobbin tube colors and scanning the bobbin tubes at each sorting station by automatic scanning means responsive upon detection of a bobbin tube having the appropriate inter-region spacing to cause removal of that bobbin tube from the conveyor at the station.
