Abstract: A pick-up device for picking up a tubular knitted article from a circular knitting machine, comprising an annular pick-up body which supports pick-up elements which can slide relative to the pick-up body along radial directions. The end of each one of the pick-up elements has a seat which can engage a region of the stem of the needle located proximate to the latch of the needle on the opposite side with respect to the head of the needle.
