Abstract: A needle for transferring stitches therefrom to adjacent needles for hosiery knitting machines comprises a shank, a head, arranged at a longitudinal end, or upper end, of the shank, and a latch which is pivoted to the shank proximate to the head, about a pivoting axis which is substantially perpendicular to the longitudinal axis of the shank and can rotate about the pivoting axis in order to open or close the head. The needle comprises at least one elastically flexible lamina, which is associated with the shank and forms, on the two opposite sides of the shank, below the latch, two receptacles, one for each side of the shank. The head of an adjacent needle can be inserted in each of the receptacles, in order to transfer the loop of knitting, from the needle being considered to the adjacent needle.

Abstract: A method and an apparatus for closing a tubular knitted article at one of its axial ends, at the end of its production cycle on a circular knitting machine for hosiery or the like. The method consists in ending the production of an article at one of its axial ends. The article is then picked up from the machine and transferred to a handling device located in a sewing or looping station. The pick-up is performed by transferring individually the loops of the last row of knitting from the needles of the machine to spikes of the handling device, which has an annular body composed of two semiannular elements. The article is then turned, and one of the two semiannular elements is turned over with respect to the other one, so that the spikes of one semiannular element face, and are aligned with, the spikes of the other semiannular element.
