  • Patent number: 4624200
    Abstract: An apparatus and method is provided for forming a double-folded wide hem in cut textile articles, such as would be used for the open entrance end of a pillowcase, the top of a bed sheet and the like. Rectangular cut articles are successively fed in a longitudinal path of travel and are stopped for hem folding during such travel. A predetermined width of one edge portion extending in the longitudinal direction of the path of travel of each article is elevated and stopped in the folding position. The elevated portion is folded over the remainder of the article and over a stationary folding shoe having a transverse dimension corresponding to the desired width of the wide hem being formed in the article, while forming a first fold in the edge portion of the article around an outer longitudinally-extending edge of the stationary folding shoe.
