摘要 |
The cover consists of two rigid panels (1) with a strap (2) across the back into which a hand can be inserted and which is attached to the panels by rivets (3), and a second strap (4) connecting the panels' lower edges so that they are held at an angle of 120 degrees to one another when open. The second strap also acts as a support for the papers placed inside the cover. The panels can be made from a strong cardboard, and the straps, which are attached to them by eyelet rivets, can be made from webbing, vinyl or coarse tape. ADVANTAGE - Improved support for pages, allowing them to be turned, especially suitable for choristers in rehearsal or concert.
