The edges of the slotway abut at intervals to form joins (4) and at other parts are diverged to form chiplessly shaped openings (5) for the flat pipes. These openings (5) can be produced by displacement and the slotway edges are extruded beyond the joins (4) to make edge strips (2,3) in prefered vee shape. In this way the section of the pipe plus slotway edges and rim strips makes up an omega shape in the one plane. The edge strips (2,3) limit the insertion depth of the pipe ends. The sheet strip is formed into an open profiled edged slotway to give the hollow profile whereupon the slotway is opened for the pipe entries and the manifold (1) finally sealed up by soldering between pipe entries (5).
