The method comprises using a set of contiguous needles of the needle cylinder; actuating the needle cylinder with an alternating rotary motion about its own axis, through a rotation angle making the knitting needles to pass in front of n feeds or drops of the machine which are used to form the pouch; gradually decreasing the needles made to knit at least one of the n feeds, excluding every time needles located at the lateral ends of the set in at least one step of the knitting process; and gradually increasing, at the lateral ends of the set, the needles that are made to knit at least one of the n feeds in at least one other step of the knitting process.

Method for forming a pouch in a tubular knitted article with a circular knitting machine

A method and an apparatus for manufacturing tubular items, particularly hosiery items, closed at an axial end. The method consists in forming the tubular item on a circular knitting machine by way of the needles of the needle cylinder, starting from the opposite axial end of the item with respect to the axial end to be closed and retaining on the needles of the needle cylinder the last formed row of knitting. The loops of the last row of knitting are then transferred individually from the needles of the needle cylinder to an auxiliary element provided with elements for individually supporting the loops. The supporting elements of at least one half-row of the last row are suitable to receive two loops and to form knitting. The item is reversed before or after transferring it and the loops of one half-row are transferred from the corresponding supporting elements to the supporting elements engaged with the loops of the other half-row. The supporting elements that support the two half-rows form at least one additional row of knitting, closing the axial end of the item, which is then unloaded from the supporting elements.

The method consists in forming a tubular item on a circular machine by means of the needles of the needle cylinder, starting from the opposite axial end of the item with respect to the axial end to be closed and retaining on the needles of the needle cylinder the last formed row of knitting. The loops of the last row of knitting are then transferred individually to an auxiliary element provided with supporting elements for individually supporting the loops, and the supporting elements of at least one first half-row of the last row are suitable to receive two loops and to pass one of the two loops in the other loop. The item is furthermore reversed before and after the transfer. In a subsequent step, the loops of the second half-row are transferred from the corresponding supporting elements to the supporting elements engaged with the loops of the first half-row, and the loops of the second half-row are knitted in with the loops of the first half-row by passing the loops of the second half-row through the loops of the first half-row, thus closing the axial end of the item. Finally, an additional operation is performed in order to stabilize the closure of the item.

Method for manufacturing closed end tubular items, in particular hosiery, on a circular knitting machine

A needle control device for stocking knitting machines, comprising a connecting element which can engage a needle or sub-needle or slider and can be arranged in the same slot of the needle holder that accommodates a needle, and an actuation element which is connected to the connecting element and can oscillate on command on a plane which is substantially parallel to the sides of the corresponding slot of the needle holder in which it is accommodated. The actuation element is provided with at least one first heel and at least one second heel which are mutually spaced along the side of the actuation element that lies opposite the side meant to be directed toward the bottom of the slot of the needle holder. The actuation element is movable, as a consequence of its oscillation, into three positions, respectively a first position, in which the heels are both inserted in the corresponding slot of the needle holder, a second position, in which the first heel protrudes from the slot of the needle holder while the second heel is inserted in the slot of the needle bolder, and a third position, in which the first heel is inserted in the slot of the needle holder while the second heel protrudes from the slot of the needle holder.
