A method for automatic pick up from a container (7) of hosiery articles, in species socks (2), knee socks and the like of knitted material. An actuator (4) brings a support (5) to which a grasping device (6) is suspended at a predetermined distance. The grasping device (6) can be pushed to approach the support (5) independently from the actuator (4). The actuator (4) and the grasping device (6) are carried integrally above a container (7) of socks (2) and lowered integrally until the grasping device (6) contacts the free surface of the bulk of socks (2). The actuator (4) continues to be lowered according to a brief additional stroke and the grasping device (6) delays the closure even after a first contact with the free surface of socks (2). The approaching of the support (5) to the grasping device (6) is then detected and the latter is closed onto socks (2) grasping at least one of them (20). Then, there is the translation of the grasping device (6) by means of the actuator (4) from a pick up position to an unloading station where the grasping device (6) opens and releases the sock (20) on a loading plane of a finishing machine. Finally, there is the back stroke of the grasping device (6) to the starting position above the container (7) for a next picking up step.
