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.

Abstract: A device for lifting a knitted item made on a circular knitting machine for knitwear and hosiery. The device includes a lifting pipe 15 coaxial inside the cylinder, rotating with this, moveable in height between a lowered position and a raised position, and one bearing a summit bell 16 with a flared lip 19, which extends above the internal sinker crown to the close vicinity of the needs and which has radial slits 20 in line with the sinkers 12.

Abstract: 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.

Abstract: A method for creating an opening in tubular knitted fabric articles on a machine including a needle cam mounted for reciprocal movement between first and second vertically-spaced positions. In the first position the needle cam lowers successive needles to a position where the loop of yarn is released from a selected loop-forming needle and transferred to a transfer needle. In the second position the needle cam lowers successive needles to a position where the loop of yarn is transferred to a transfer needle adjacent the selected loop forming needle without being released from the selected loop-forming needle to thereby form a no-run stitch in the knitted fabric. A needle is selected from which a loop is to be transferred and the loop is enlarged on the selected needle by deflecting the loop out of the vertical plane of the selected needle laterally into the vertical plane of an adjacent needle while the adjacent needle is in a lowered, non-interfering position relative to the deflected loop.

Abstract: 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.

Abstract: A method for producing tubular items, such as hosiery items and the like, which are closed at an axial end, using a single-cylinder circular knitting machine provided with a half-dial which faces, in an upward region, a first half of the needle cylinder and has hooks which can move in a radial direction with respect to the axis of the needle cylinder, each hook being arranged between two contiguous needles of the half of the needle cylinder that it faces. The half-dial can turn over about a diametrical axis of the needle cylinder so that its hooks face the needles of the second half of the needle cylinder. The hooks can move in a radial direction with respect to the axis of the needle cylinder in order to engage portions of loops of knitting formed by the needles of the first half of the needle cylinder before the half-dial turns over and in order to release the portions of loops of knitting to the needles of the second half of the needle cylinder after the half-dial has turned over.

Abstract: A single-cylinder circular knitting machine, including a needle cylinder and a circular plate that is arranged above the needle cylinder and coaxially thereto. The circular plate is constituted by two portions, one of which can rotate with respect to the other about a diametrical axis of the circular plate. An actuation device is also provided which acts on command on the portion of the circular plate that can rotate with respect to the other one, in order to move it from a first position, in which it is co-planar with respect to the other portion, to a second position, in which it is arranged so as to face the other portion from below, or vice versa.

Abstract: In a first step of the method for manufacturing socks with a single-cylinder circular knitting machine a needle cylinder is oscillated about its own axis with an oscillation angle of about 180.degree. to move half of the needle cylinder that faces a half-platen such that it passes in front of a feed of the machine. During these oscillations, engagement elements are extracted radially from the half-platen towards the needles of the machine, at least one thread dispensed at the feed, and lifting to the knitting position, at each oscillation, 1/n uniformly spaced needles of the mentioned half of the needle cylinder, varying the needles that are moved into the knitting position in the subsequent oscillation or oscillations, and lowering the needles after engaging the thread or threads, which rests on the engagement elements. A second step is then performed, during which the engagement elements are retracted towards the half-platen, retaining the thread or threads that rest thereon.

Abstract: Method and means for transferring knit loops from single-hook needles on one cylinder to single-hook needles on the other cylinder of a double cylinder circular knitting machine. In the method and needles are displaced at an inclination outwardly of their cylinders to allow axial sliding of the opposing needles behind the inclined needles and into the loops held on the inclined needles; the inclined needles are then withdrawn to shed the hooks, which are then received on the hooks of the other needles. The means includes radial pins slidably carried in the cylinders for engagement and operation by stationary radial cams located within the cylinders, the pins extending through the cylinders and into engagement with the stems of the needles for radially displacing the needles outwardly to the inclined positions required by the described method.
