Beschreibung
Zusammenfassung:	A fan includes a hub configured to be driven by motor to rotate about a fan rotational axis, blades that protrude radially from the hub and a band that surrounds the rotational axis and connects the tips of the blades. The band includes features that structurally reinforce the knit lines. In some embodiments, the features are thickened regions that protrude from outer surface of the band in a direction away from the hub. A thickened region is disposed between respective tips of each pair of adjacent blades. In some embodiments, the features are structurally-reinforcing ribs that protrude from the hub-facing surface of the band. A rib is disposed between respective tips of each pair of adjacent blades. In some embodiments, the features are both ribs and thickened regions.
