The invention relates to a method for producing polyamides by means of a spray nozzle arrangement for the collision of spray jets, comprising at least one spray nozzle forming a first spray jet having a first spray jet cross-sectional surface and a first spray jet longitudinal extension axis, and comprising a second spray jet forming a second spray jet having a second spray jet cross-sectional surface and a second spray jet longitudinal extension axis, wherein the first and second spray jets have a spray direction that is facing the gravitational field, and are arranged opposite one another such that in a spray direction facing the gravitational field, the formed spray jets collide in a collision area. The invention is characterized in that the angle between the first and the second spray jet is in the range of 5° to 170°, and that the first and second spray nozzles are arranged such that upon colliding, the first spray jet cross-sectional surface of the first spray jet forms an intersection with the second spray jet cross-sectional surface of the second spray jet. |
