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.

The head is equipped with a needle-holding element having a plurality of needles arranged around a central axis; a first and last active needle delimit a dead zone of the element without needles, and an arc-shaped operating zone with active needles. The head has a control device connected to the active needles to selectively actuate them to produce an open knitted fabric extending between two side edges making up two selvedges of the fabric. The assembly is downstream from the head with respect to feeding direction of the fabric, configured for rotating integral or coordinated with the element during production. Further, at least a first cutting device, configured for progressively cutting and/or trimming the produced fabric.

Abstract: A method for sewing an open end of a tubular textile item so as to make the toe of a sock or of a leg of a stocking, comprising the steps of: loading a tubular item onto a preparation mold, and flatten it to define a first side and a second side; pulling the end portion of the first side so that is elongated, with respect to the end portion of the second side, of a determined length; by keeping the end portion of the first side pulled, simultaneously blocking the two sides so as to make them as one piece; by keeping the two sides blocked, releasing the end portion of the first side, taking the preparation mold out of the tubular item, and simultaneously placing the end portions of the two sides to sewing devices, so as to make a closed toe of the tubular item.

Abstract: A method for preparing a tubular article, such as a sock or the like, for automated pickup at the end of its forming on a double cylinder circular machine with at least one feed or drop, and to a double cylinder circular machine for the execution thereof. The method in question is executed on a machine with at least one feed or drop (100) and with the needle cylinders (4, 5) actuatable with a rotary motion about their own axes (3) with respect to needle actuation cams, to cams (34) for actuating the knockover sinkers (33) and to the feed or drop (100).

Abstract: A needle-holding element for circular knitting machines, having a structure as a hollow solid of rotation developing around a central axis and configured for rotating and for supporting a plurality of needles moving so as to produce a knitted fabric; the needle-holding element has at least one working surface shaped as a surface of rotation obtained through the rotation of a portion of generating straight line around the central axis; on the working surface a plurality of needle seats is defined, placed one beside the other and arranged circumferentially or radially around the central axis, wherein each needle seat movably houses at least a portion of at least one respective needle. At least one needle seat has at least a first length has a longitudinal development, on the working surface, inclined with respect to the generating straight line.

Abstract: A device for feeding yarn or yarns for knitting machines for hosiery or the like, comprising a supporting structure which supports at least one yarn finger having an elongated shape and being pivoted, at an intermediate portion thereof, to the supporting structure about a corresponding rotation axis and having, proximate to a longitudinal end thereof, a passage for the yarn or yarns to be fed to the needles of the knitting forming machine, the device for feeding yarn or yarns comprising an electromagnetically actuated device which comprises at least one magnet which is fixed to the at least one yarn finger and at least one electric coil which is laterally adjacent to the at least one yarn finger and is connected to the supporting structure.
