摘要

In a rolled hollow profile (1) for spacing the panes of multi-pane insulating glazing, a plurality of air passages (12) are provided in the profile wall (11) directed towards the pane interior. The longitudinal edges (13 and 14) of the metal sheet forming the profile are connected together by a seam. This seam connection is here provided on the wall opposite to the profile wall (11) which is perforated to let air pass, the sheet metal edge sections (13, 14) being additionally clamped together in the transverse direction in the region of the seam connections. <IMAGE>
