  • Patent number: 11015270
    Abstract: A turning device for knitted tubular articles, particularly for turning inside-out tubular articles with pockets that protrude from the lateral surface thereof. The turning device in question comprises a main supporting structure which supports a tubular body arranged with its axis substantially vertical. The tubular body has its upper axial end beveled along a plane that is inclined with respect to its axis. The turning device comprises first actuation means which can be activated to perform a translation of the tubular body along its axis with respect to the main supporting structure. The tubular body is insertable, with its upper axial end, through an axial end of a tubular article in order to turn it inside out. The turning device comprises second actuation means which can be activated to rotate the tubular body about its own axis, through an angle of preset breadth, with respect to the main supporting structure.
