ABSTRACT:
A roller apparatus is provided for a flexible web such as a map, chart, window shade or the like which is provided on at least one free margin thereof with a rigid, elongated holder element of predetermined cross-sectional dimensions which are substantially greater than the thickness of the flexible webbing material. The roller apparatus comprises a rigid, elongated tubular roll of substantially greater dimensions than the predetermined cross-sectional dimensions of the holder element and including a longitudinal through slot of a cross-sectional dimension smaller than that of the holder element and greater than the thickness of the web. An end cap is non-rotatably attached to either end of the tubular roll. At least one of these end caps includes a through opening of dimensions at least as great as the cross-sectional dimensions of the holder element and peripherally communicating with the through longitudinal slot of the tubular roll for slidably receiving the holder element with the flexible webbing affixed thereto and depending through and below the longitudinal slot. Thus, the holder element and the flexible webbing depending therefrom are slidably insertable into the tubular roll selectively from either right-hand or left-hand margins of the flexible webbing so as to selectively reveal either surface of the flexible webbing with respect to a fixed observer.
