Abstract
A protective covering for annular objects, such as caster wheels, which covering consists of a continuous band of heat-shrinkable plastic material defining spaced marginal edges thereabout, which band is proportioned thereabout to be closely received over and about the tread of the caster wheel in overlapping relation to the wheel along both side edges of the wheel tread, for heat shrinking thereagainst, whereby the band is tensioned against the wheel tread, and the wheel tread side edges, in protective relation to the tread, which band is formed to provide what becomes a tear or release strip that functions to sever the band, when removal of the covering is desired, from one side edge of the band to the other. When removal of the covering from the wheel tread is desired, the tear strip is created by pulling or peeling a designated portion of the covering laterally outwardly of the wheel tread, and from one side edge of the covering to the other side edge of same, to sever the protective covering, which covering then springs free of the wheel tread. A method is disclosed for application of the protective covering over the wheel tread.
