1. A method of applying inherently resilient tubular sleeves to objects comprising:

  • a) sequentially delivering objects and sleeves, each one at a time to an associated one of a set of sleeving stations, the objected delivery including conveying the objects along an input path in a plane;

    b) sequentially expanding and stretching each sleeve to a cross-sectional configuration generally corresponding to the cross-sectional configuration of an object to be sleeved;

    c) relatively moving an expanded sleeve and a delivered object vertically to position the expanded sleeve around the delivered object;

    d) introducing fluid to provide a lubricating gas film between the expanded sleeve and the delivered object concurrently with the relative motion step thereby facilitating the positioning of the expanded sleeve on the delivered object;

    e) thereafter stopping the fluid flow to allow the inherent resiliency of the sleeve to shrink the sleeve into circumferential engagement with the object; and

    ,f) removing each delivered object from its station by moving it along an exit path at a level spaced from said plane.
