Abstract
A spinning apparatus for melt spinning a synthetic multifilament yarn, which includes a spin head having a plurality of narrowly spaced apart spin packs with spinnerets, through the nozzle bores of which the filaments are extruded. Downstream of the spinnerets, the filaments advance through cooling tubes, which connect to an air stream generator that produces an air stream in the direction of the advancing yarn. The cooling tubes are mounted for movement to a lowered servicing position, and sealing units are provided for connecting the cooling tubes to the spin head when in the raised operative position. The sealing units form a separating plane arranged on the side of the spin head and a separating plane arranged on the side of the cooling tube, and the separating plane on the spin head side is located on the spin pack. A very compact arrangement of the spin head and the cooling tubes is thereby enabled.
