An apparatus is described for cooling a strip (1) of sheet metal with nozzles (6) for a cooling liquid to be sprayed onto the bottom side of the strip, which nozzles are arranged beneath the strip (1) in transversal rows relative to the feeding direction (3) of the strip. In order to provide advantageous cooling conditions it is proposed that the nozzles (6) configured as fan jet nozzles form a common middle spraying surface (7) for each transversal row and that covers (10) are provided in the spraying region of the nozzles (6) which are laterally adjacent to the strip (1) of sheet metal.
