The linking device (9) includes a first bowed needle (17) mounted on a first shaft (13) and a second bowed needle (19) mounted on a second shaft (15). The first shaft (13) and the second shaft (15) are mutually inclined to each other and are controlled in order to pivot alternatingly around a pivot axis (A-A) of the first shaft (13) and a pivot axis (B-B) of the second shaft (15), respectively. The first shaft (13) is rigidly coupled to a first pin (27) pivoting therewith; the second shaft (15) is rigidly coupled to a second pin (31) pivoting therewith; and a slider (35) is slidingly mounted on the first pin (27) and on the second pin (31).

The method provides for arranging a pick-up member for the tubular knitted article (M) coaxially with the needle cylinder, when knitting has been completed. The pick-up member (23) is provided with a plurality of pick-up hooks (25A, 25B) arranged according to a circular ring subdivided into two circular half-rings that can be overturned over each other. The tubular article is engaged by the pick-up hooks while the stitches of the last course of the knitted article are still held by the needles (5) of the knitting machine. The stitches of the last curse are then removed from the needles and the tubular article is removed from the needle cylinder (3) by means of the pick-up member (23). The two half-rings of pick-up hooks are overturned one onto the other, putting one of two opposite edges of the toe of the tubular article onto the other. The two edges are then sewn or linked.

A reed tooth for a hosiery stitching machine, which includes a fixed reed, includes a positioning portion for positioning to the fixed reed, first arid second sidewalls, and an intermediate wall cooperating with the first and second sidewalls to define a slide groove. The first sidewall has a tapered bottom end that includes a bottommost tip and an inclined edge. The second sidewall has a length shorter than that of the first side wall, and has a tapered bottom end that includes a bottommost end, and an inclined edge that extends upwardly from the bottommost end of the second sidewall. The inclined edge of the second sidewall and the inclined edge of the first sidewall cooperatively define a bottom opening of the slide groove.

A transfer apparatus for transferring a stocking from a knitting machine to a stitching apparatus to close an open-end of the stocking includes strip and transfer members. The knitting machine includes a needle having a hook for forming a loop at the open-end of the stocking, and a latch to move to or away from the hook. The strip member is movable axially upward and downward and radially towards and away from the needle, and is capable of contacting the loop on the needle to push the loop toward or away from the hook. The transfer member is disposed horizontally above the strip member, is movable axially upward and downward and radially toward and away from the needle, and includes a tip region for receiving the loop from the hook when the strip member pushes the loop to the hook.
摘要:
A pick-up device for picking up a tubular knitted article from a circular knitting machine for hosiery and for transferring the article to a unit adapted to perform additional work thereon. The device comprises an annular pick-up body that supports pick-up members that can slide with respect to the pick-up body along radial directions. The pick-up body can be arranged coaxially around the needle cylinder of a circular knitting machine for hosiery so that each one of the pick-up members faces laterally a needle of the machine. The end of each one of the pick-up members that is directed toward the axis of the pick-up body has a seat that can engage a region of the stem of the needle that is arranged 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 that act on the pick-up members for their sliding toward the axis of the pick-up body and radial pushers that act on the pick-up members for their sliding away from the axis of the pick-up body in contrast with the action of the elastic elements.

A system is disclosed for closing the point of a stitch circular product, and particularly of a stocking, without a significant interruption of the sewing operation. In one embodiment, circular device is inserted inside the cylinder used for producing the stocking, which, appropriately programmed, catches the stitch from under the needles and carries it to the sewing machine.
摘要:
A method for transferring a portion of knitting produced by a group of needles to another group of needles of a bed in circular hosiery knitting machines with two beds or the like, in which the two beds are coaxial and face each other. At least one first bed (1) is provided with needles (11,12,13) for forming knitting, and a second bed (4) is provided with knitting engagement elements (41,42,43), which can be actuated in order to retain or pick up loops of knitting (60) formed by the needles of the first bed or to release loops of knitting, retained or picked up previously, to the needles of the first bed. The method comprises a step, performed by means of the engagement elements (41,42,43) arranged in a first sector (D) of the second bed (4), for engaging a row of knitting formed by the needles (11,12,13) arranged in a first sector (A) of the first bed (1) and a step for the angular offset of the second bed (4) with respect to the first bed (1) around the common axis (1a), in order to move the first sector (D) of the second bed (4) closer to a second sector (B) of the first bed (1); a step for releasing the row of knitting (60) previously engaged by the engagement elements (41,42,43) arranged in the first sector (D) of the second bed (4), to the needles (14,15,16) arranged in the second sector (B) of the first bed (1) and, during the engagement step or the release step, a reversal of the orientation of the row of knitting affected by the transfer.
摘要:
New stitches on knitting machines are formed by producing two stitches from one stitch suspended on a knitting needle, in that the stitch suspended on the knitting needle is transferred by a transfer element associated with the knitting needle and subsequently a new stitch loop is pulled from the knitting needle through the stitch suspended on the transfer element.
