摘要： An electrically heatable hair wrapper capable of being cut to any predetermined length from a flat, elongated, flexible base carrying a plurality of parallel resistance heating circuits. The circuits extend along the length of the base in a periodic serpentine pattern with the opposite ends of each pattern being electrically connected to continuous parallel buses extending along the longitudinal edges of the base. The flexible base is provided with indicia for indicating where the base and buses may be cut intermediate each adjacent pair of serpentine patterns so as not to destroy the continuity of the selected resistance heating circuits. A bendable, shape-retaining, cuttable wire along each longitudinal edge of the base outwardly of the parallel buses holds the wrapper in any desired shape. A longitudinally flexible flap integrally formed with at least one longitudinal edge of the base is foldable over the base to retain a hair tress between the base and flap during use of the wrapper.
