Classes 16 and 146(1) A transparent document cover of synthetic plastic foil sheets 1 has a reinforcing frame 2 consisting of a wire 3 of spring steel embedded in a plastic covering 4 having on its periphery a continuous narrow edge 5 by means of which the frame 2 is welded to the edges of the plastic sheets 1. The edge 5 may be placed between the sheets 1 as in Fig. 4 or lie outside the sheets as in Figs. 1 and 7. The ends of the wire 3 are joined by a sleeve 6 inside the covering 4 or by a split sleeve outside the covering. As shown in Fig. 1, the top edge of one sheet 1 is shorter than the other and not welded to the frame to provide the opening for documents. An aperture 7 is used for suspending the cover from a rod. In an alternative cover, holes are provided down one side for filing in a ring binder. As shown in Fig. 7, two covers, with both sheets welded all round to the edge 5, are joined together for a book or loose leaf cover or folder, the hinges being welded strips 9' on each cover joined by an endless loop 9<SP>11</SP>. A reinforcing insert may be placed between the two sheets 1 for each cover.
