Abstract Method and apparatus for heat-treating tubular. elastically expandable material A method is indicated for heat-treating tubular, elastically expandable material, especially for drying and/or smoothing stockings, pantyhose, and the like, in which the material is stretched on at least two adjacent limbs of an elongated stretcher and then acted upon by heat for drying and/or smoothing purposes. During heat treatment the limbs are moved so as to rotate about their long axis, with the direction of the rotating movement preferably being alternately reversed. This eliminates the occurrence of streaks, especially in the stretching of stockings, pantyhose, and the like. A suitable apparatus has at least one elongated stretcher with at least two adjacent limbs on which the material can be stretched, and is provided with a heating device for heating the material. The limbs of the elongated stretcher are mounted rotatably about their long axis, and are connected to a drive device, for example by means of a chain drive.
