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 an 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 for internally receiving the holder element and including in a peripheral wall thereof 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. One of these end caps is either removably mounted to the tubular roll, or alternatively is provided with a through opening of dimensions at least as great as the cross-sectional dimensions of the holder element and peripherally communicating with the through longtitudinal slot of the tubular roll, for slidably inserting the holder element into the tubular roll with the flexible webbing depending through and below the longitudinal slot. Thus, a plurality of holder elements with flexible webbings depending thereform are interchangeably slidably insertable into the tubular roll. Moreover, each holder and depending flexible webbing may be inserted from either right-hand or left-hand margins of the flexible webbing so as to selectively reveal either surface of the flexiable webbing with respect to a fixed observer.
