Abstract
Abstract Disposable fitted sheets and method for making them. The sheets are formed without necessitating prior cutting by folding edges of the material and attaching the folded-over edges along diagonal lines associated with each corner. Elastic bands cooperate with each pocket to maintain the fit on the corners of the mattress. The bands are fastened in a stretched condition to the folded-over edges while the sheet is in a flat state. The process of the invention is particularly adapted to continuously forming such sheets which may be formed from a variety of inexpensive materials. Sheets of the invention are particularly useful in hospitals and nursing homes where frequent bedding changes may be needed.
