The outside of the recovery frame 22 is connected to a recovery pipe 211 for extracting cooling water from the inside of the recovery frame 22. The galvanized iron wire moves in the cooling water trough 24 and is guided by the wire pressing wheel 210 to ensure that the iron wire is evenly cooled in the cooling water trough 24.
