Claim:
A method for the production of a frame-shaped spacer for insulating glass panes which comprise two individual glass plates spaced by adhering the spacer to the two individual glass plates, comprising the steps of: selecting a hollow profile bar, which comprises an outer wall, an inner wall opposite the outer wall and two oppositely disposed flanks connecting the inner and outer walls, the flanks each comprising a middle flat partial region disposed substantially parallel to the two individual glass plates including an inner side recessed partial region between the middle flat partial region and the inner wall and an outer side recessed partial region between the middle flat partial region and the outer wall, where the length of the inner wall and the outer wall are narrower than the distance between the middle flat partial regions of the flanks and wherein the hollow profile bar is airtight or gastight and also empty wherein the hollow profile bar does not contain a desiccant; and forming the frame-shaped spacer by bending the hollow profile bar at least two times.
