The invention relates to a spin beam for spinning a plurality of synthetic filament yarns, and which has the shape of an elongate, hollow parallelepiped block formed by two side walls, a lower wall, an upper wall and end walls. The spin beam comprises a number of pressure-tight spin heads with downwardly extending spinnerets arranged in at least one row on a lower support. An upper support mounts at least one multiple pump which is connected, via distribution lines, to the spin heads. A pump connection plate is joined to the upper support for each multiple pump. Each of the distribution lines is connected on the one hand to the pump connection plate and on the other hand to one of the spin heads, the distributing lines forming together with the pump connection plate, the spin heads, and the lower support, form a self-supporting distributor unit. The lower support forms a portion of the lower wall of the spin beam, and the side walls are mounted on the lower support of the self-supporting unit. This arrangement allows the assembly of the spin beam from inside out, and to thus produce it in a more cost-favorable manner, with more spin heads, and for easier testing.
