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.

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.

Abstract: There is disclosed a device for attachment to a free margin of flexible webbing material, as for example, a map, wherein the device comprises an elongated mounting strip to which the free margin of flexible webbing material may be affixed and a rigid elongated substantially hollow holder element having an open end, an outer wall, and a longitudinal slot within the outer wall having a width approximating the thickness of the webbing material. The outer wall is continuous in cross-section circumferentially from one edge of the slot to the other edge of the slot. The holder element further includes elongated rib means within the holder element extending substantially the entire length thereof. The rib means defines an aperture communicating with the slot and is shaped to accommodate the mounting strip lengthwise through the open end with the webbing material extending through the slot.
