An air-cooling device for the shuttle rotation path 32, carrying the reed dents, of a circular weaving machine with a lower shuttle rotation path and with an air-duct device. The components of the lower shuttle rotation path possess two horizontal air partitions 2, 4, a vertical wall 3 and a row of tooth blocks 7, the components of the air-duct device containing a nozzle 13, a flanged rib 11, a duct bottom 5, a cold-air connection 14, 29 and a vertical wall 6 which serves as an air partition, the cold air which flows through the air conduit being supplied to the cold-air connection 14, 29 and flowing through the air chamber 9, 24 to perforations 8 and through the air nozzle 10 which consists of trumpet- shaped walls 13, the air finally being blown out through the air slit 12, in order to discharge the frictional heat of the shuttle rotation path, the cold-air flow being a laminar flow.
