Abstract

A device for meltblowing of synthetic fibers utilizes an elongated spinneret packet that is held at the bottom side of the spinneret carrier. In order to supply process air the two elongated air tubes extend at the opposite longitudinal sides of the spinneret carrier, which are connected to an air distribution device having an air channel system in the spinneret carrier. In order to avoid thermal stress in the expansion joints between the air distribution device and the spinneret carrier as much as possible, the air distribution devices are embodied by means of multiple distribution segments having an expansion joint between adjacent distribution segments.
