    Abstract: A circular machine for knitting, hosiery or the like, with sinker actuation device, comprising a needle cylinder (2), arranged so that its axis (2a) is substantially vertical and actuatable with a rotary motion about the axis (2a) in both directions of rotation. The needle cylinder (2) has, on its lateral surface, a plurality of axial grooves (3), each of which accommodates a needle (4) that can move on command along the corresponding axial groove (3) in order to pick up at least one yarn dispensed at least one feed or drop (5) and form knitting. The machine also comprises needle actuation cams (10), which face the lateral surface of the needle cylinder (2) and define paths that are extended around the axis (2a) of the needle cylinder (2) and can be engaged by at least one heel (4a) of the needles (4), which protrudes from the lateral surface of the needle cylinder (2), in order to actuate the movement of the needles (4) along the corresponding axial groove (3) with respect to the needle cylinder (2) as a consequence of the rotation of the needle cylinder (2) about its own axis (2a) with respect to the needle actuation cams (10) and the at least one feed (5). The machine also comprises a sinker ring (6), which is integral with the needle cylinder (2) in rotation about its own axis (2a) and is arranged coaxially to the needle cylinder (2) at its upper end. The sinker ring (6) supports a plurality of sinkers (8) that can move radially with respect to the needle cylinder (2) and to the sinker ring (6). The machine also comprises a sinker cap (9), which is arranged above and coaxially with respect to the sinker ring (6) and supports sinker actuation cams (10) that define at least one path that is extended around the axis (2a) of the needle cylinder (2) and can be engaged by a heel (8a) of the sinkers (8), which protrudes upwardly from the sinker ring (6), in order to 2 actuate the movement of the sinkers (8) along a radial direction with respect to the needle cylinder (2) and to the sinker ring (6) as a consequence of the rotation of the needle cylinder (2) about its own axis (2a) with respect to the sinker cap (9), to the at least one feed (5) and to the sinker actuation cams (10). The needle actuation cams (41) comprising two needle lifting cams (45, 46), respectively a first cam for lifting the needles to the tuck or dropped position (45) and a second cam for lifting the needles to the tuck or dropped position (46), which are arranged on mutually opposite sides with respect to an imaginary plane that passes through the axis (2a) of the needle cylinder (2) and through the at least one feed or drop (5) of the machine. The sinker actuation cams (10) comprise two pusher cams (12, 13), respectively a first pusher cam (12) and a second pusher cam (13), arranged on mutually opposite sides with respect to an imaginary plane that passes through the axis (2a) of the needle cylinder (2) and through the at least one feed or drop (5) of the machine. The pusher cams (12, 13) can engage the heel (8a) of the sinkers (8) to cause the movement of the sinkers (8) toward the axis (2a) of the needle cylinder (2). In the machine, the first pusher cam (12) and the second pusher cam (13) are arranged respectively at the first cam for lifting the needles to the tuck or dropped position (45) and at the second cam for lifting the needles to the tuck or dropped position (46) and can move with respect to the sinker cap (9) toward or away from the axis (2a) of the needle cylinder (2). Actuation means (15) are provided which act on the first pusher cam (12) and on the second pusher cam (13) in order to move alternatively the first pusher cam (12) or the second pusher cam (13) toward the axis (2a) of the needle cylinder (2) or away from the axis (2a) of the needle cylinder (2).

    Abstract: A turning device for tubular knitted articles, particularly for sewing or looping stations for the automated closing of tubular articles at an axial end thereof comprising a lower portion and an upper portion, which are arranged respectively below and above an intermediate region at which elements are or can be positioned for supporting the tubular article to be turned, which hangs at one of its axial ends and is arranged substantially vertically, a tubular body, which can be inserted from the bottom upwardly, with its upper axial end, through the axial end of the article that hangs from the supporting elements, so as to evert the article onto the outer lateral surface of the tubular body, extracting it progressively from the upper axial end of the tubular body. Auxiliary sliding elements are provided, which can move on command with respect to the tubular body, parallel to the axis of the tubular body, and can engage and disengage cyclically the article everted onto the outer lateral surface of the tubular body in order to produce its sliding toward the lower axial end of the tubular body.

    Abstract: A circular knitting machine for hosiery or the like, which comprises a needle cylinder (2) which has a vertical axis and has, on its lateral surface, multiple axial slots (3), each of which accommodates a needle (4) and an actuation element (5) for the needle (4). The actuation element (5) comprises at least one connecting element (6). The connecting element (6) is provided with a movable heel (6a), which can be extracted radially from the axial slot (3), by way of the oscillation of the connecting element (6) on a radial plane of the needle cylinder (2) to make it engage connecting element actuation cams which face the lateral surface of the needle cylinder (2). The cams comprise at least one extraction cam or one retraction cam, which has a portion whose profile is inclined with respect to an ideal plane which is perpendicular to the axis of the needle cylinder (2). The machine comprises extraction means (39) for causing the extraction of the movable heel (6a) of the connecting element (6) and keep the movable heel (6a) in the extracted position substantially over the entire extension of the portion having an inclined profile of the extraction cam or of the retraction cam.

    Abstract: A circular knitting machine for hosiery or the like, which comprises at least one needle cylinder which has a vertical axis and on the lateral surface of which there are axial slots. Each of these axial slots accommodates a needle (106) and an actuation element (110) for the needle (106) which can engage, with one of its ends, the needle (106) arranged in the same axial slot. The needle (106) or the actuation element (110) is provided with a fixed heel (103 a), which protrudes radially from the axial slot, and a movable heel (104a) which can be extracted radially on command from the axial slot. Actuation cams are arranged around the needle cylinder and can be engaged by the fixed heels (103 a) and by the movable heels (104a) in the extracted position. The machine can perform the usual knitting of known types of machine despite having an actuation cam set which has an extremely small number of actuation cams which can move for activation or deactivation, or none at all.
