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.
Claims6
A device for meltblowing synthetic fibers having an elongated spinneret packet that is held at a bottom side of a spinneret carrier, the device comprising:
- two elongated air tubes extending at opposite longitudinal sides of the spinneret carrier,
- two air channel systems embodied opposite of each other in the spinneret carrier, by means of which process air is supplied to the spinneret packet, and
- two air distribution devices, which are attached on the longitudinal sides of the spinneret carrier, and which connect the air tubes to the air channel systems for the distribution of the process air, the air distribution devices including multiple distribution segments arranged at the longitudinal sides of the spinneret carrier in a distributed manner, each distribution segment being separated from at least one other distribution segment by an expansion joint,
- wherein each distribution segment includes a distribution block that attaches to the spinneret carrier and a supply line that connects to the air tubes.
