Abstract
Cover folders having binders that securely retain the cover and inserted sheets, without the use of external fasteners. The binder is an elongated bar with an interior channel for receiving and holding a folded cover. The bar includes within the channel slanted ribs which engage the folded edge of the cover sheet along an overlapping flap. The overlapping flap of the cover sheet may be made more rigid by heat treatment and/or by a reinforcing coating.
