A feed manifold bar for an injection mould having a central pin gate. The technical problem is the provision of a feed manifold bar which, using hot-runner technology, permits a small distance between central pin gate points arranged in a row. A feed channel (6) aligned in the longitudinal direction of the feed manifold bar (1) is connected to a hot-runner nozzle (3) which opens perpendicularly. Gate nozzles with gate runners (6) and a dome-shaped head (11) are moulded-on in one piece emerging perpendicularly from the feed channel (6) and parallel to the hot-runner nozzle (3). Each gate nozzle is surrounded at the base of the nozzle head by a supporting sealing ring (14) which projects beyond the respective base surface (12) of the feed manifold bar (1). <IMAGE>
