A hydro-extracting apparatus for drying cheeses of yarn comprises a rotary table having a plurality of spindles mounted thereon, on which spindles cheeses of dyed yarn are mounted vertically, a device for holding and conveying the cheeses one by one, which device includes a cheese lifting mechanism and a movable arm mechanism having chucks for engaging and releasing cheeses, this device being adapted for conveying cheeses one by one from the spindles of the rotary table to a hydro-extractor and, after hydro-extraction, to deliver the cheeses one by one to a cheese receiving unit, and a centrifugal hydro-extractor for hydro-extracting each of the cheeses, which hydro-extractor is laterally spaced apart from and adjacent to the foregoing device for conveying the cheeses. A flexible drive shaft and a spring are provided in the hydro-extractor to absorb vibrations, whereby hydro-extraction of dyed cheeses can be performed intermittently, consecutively and efficiently.
