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.

Abstract: A removal device for removing a knitted tubular manufacture from a circular knitting machine, comprising an annular removal body which supports a plurality of removal members arranged around the axis of the removal body, the removal body being arrangeable coaxially around the needle cylinder of a circular knitting machine, wherein the removal members are supported by a first annular portion and a second annular portion which can rotate with respect to each other about an oscillation axis to pass between a removal condition, in which they are arranged so as to form a circumference that is coaxial with the axis of the removal device, and a sewing condition, in which the annular portions are arranged so as to face each other.

Abstract: A method for closing a knitted tubular manufacture at an axial end thereof, comprising:—producing the manufacture up to execution of the last course of knitting;—gripping the loops;—removing the manufacture, retaining each loop of the last course formed;—positioning the manufacture at a sewing station;—transitioning the loops from pickup elements to spikes of a handling device;—inverting the manufacture retained by the handling device;—superimposing each one of the loops of one half course of knitting on a corresponding loop of the other half course of the last course of knitting;—sewing pairs of loops of knitting that are mutually superimposed;—disengaging the manufacture from the handling device, the s removal step of the manufacture comprising a first extraction preparation step, a second manufacture extraction step, and a third manufacture transfer step.

Abstract: A circular hosiery knitting machine comprising a needle cylinder which can be actuated with a rotary motion about its own axis, arranged vertically, and on the skirt of which there is a plurality of axial grooves, each accommodating a needle, a tubular body being arranged internally and coaxially to the needle cylinder and being adapted to receive the manufactured item during its forming; the tubular body is supported so that it can slide along an axial direction within the needle cylinder; and actuation means which act on command on the tubular body in order to actuate its axial movement with respect to the needle cylinder, the actuation means being associated with means for controlling the speed of the tubular body.

Abstract: A method for providing intermediate manufactures for production of manufactures such as an inshoe, footlet, no-show sock, shoes or the like with double thickness, with a circular hosiery knitting machine and an intermediate manufacture obtained with the method. The method has the particularity that it comprises at least the following steps: a step of providing a first tubular portion of knitted fabric; a casting-off step, in which a portion of knitted fabric is provided by moving to knit a group of contiguous needles at the at least one feed; a casting-on step, in which a portion of knitted fabric is provided by moving to knit a group of contiguous needles at the at least one feed; a step of providing a second tubular portion of knitted fabric by actuating the needle cylinder with a continuous rotary motion about its own axis in one direction of rotation.

Abstract: A removal device for removing a tubular knitted manufacture from a circular knitting machine for hosiery or the like, comprising an annular removal body which supports a plurality of removal members arranged around the axis of the removal body, which is arrangeable coaxially around the needle cylinder of a circular knitting machine; the removal members are supported by first and second annular portions, which can move by rotation with respect to each other about an oscillation axis in order to pass between a removal condition and a sewing condition, in which the annular portions are arranged so as to face each other, the removal members forming a respective removal head which can move on command along a removal trajectory which has a component that is parallel to the axis of the removal body and at least one radial component away from the axis.

Abstract: A semi-finished component for the manufacture of knitted uppers, comprising a plain knitting and a purl knitting, and at least one longitudinally extended channel which is formed within the knitting between the plane formed by the plain knitting and the plane formed by the purl knitting, the at least one longitudinally extended channel being engageable by an elongated engagement element which forms a lace or a reinforcement element designed to engage with a lace.

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. The device comprises actuation elements formed by elastic elements which act on the pick-up elements for their sliding toward the axis of the pick-up body and radial pushers which act on the pick-up elements for their sliding away from the axis of the pick-up body in contrast with the action of the elastic elements.
