摘要： To blow a yarn toward the needles and release it from the gripping device upon yarn feeding in a circular knitting machine, in particular a double cylinder one, a device is provided which is synchronized with each yarn feeding finger regardless of the number of feeds. The device comprises a control cam provided with a boss and rotated synchronically with the needle cylinder(s), an actuating cam provided with two oppositely located notches and connected to the control cam through a normally disengaged coupling controlled by the machine program, and an actuating lever which follows the profile of the actuating cam and controls a valve to cause it to engage with the control cam and be operated by the boss thereof to deliver pressurized air to the yarn feeding area. The valve can be moved into the operative position by means of each yarn feeding finger associated with one feed.

摘要： A circular knitting machine in which for switching from continuous rotary motion to reciprocating motion and vice versa there is provided a coupling member rotatively rigid with a shaft and axially displaceable between two pinions, idly arranged on the shaft. One pinion is constantly reciprocated by a reciprocable toothed sector, while the other pinion is constantly rotated. The coupling member is alternately engageable with a respective one of the pinions, so as to cause the shaft, which is operatively connected to the needle cylinder(s), to reciprocate or rotate. A control lever is pivoted to the stationary structure of the machine and has one end slideably engaging the coupling member and the other end slideably engaging two rotatable cams, which provide angular displacement of the control lever to cause axial displacement of the coupling member. The cams can be uncoupled from a cam driving shaft rotated by the main drive of the machine.

摘要： A double-cylinder circular knitting machine with latch needles and a device for automatically causing the latches of the needles operating in the upper needle cylinder to open before knitting. The device comprises cams defining a path for the needle-free sliders of the lower needle cylinder which lies constantly all around the cam box at a level corresponding to that at which the tips of the sliders engage the latches of the rib needles to open them. The needle-free sliders are selectively passed into this path and are subsequently returned into the normal knitting path when knitting plain fabric. The arrangement of the continuous path at a constant level all around the needle cylinder allows a more simple configuration of the latchguard cams and less wear and stresses in the needle latches.

摘要： 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.

摘要： A turning device for knitted tubular articles, particularly for turning inside-out tubular articles with pockets that protrude from the lateral surface thereof. The turning device in question comprises a main supporting structure which supports a tubular body arranged with its axis substantially vertical. The tubular body has its upper axial end beveled along a plane that is inclined with respect to its axis. The turning device comprises first actuation means which can be activated to perform a translation of the tubular body along its axis with respect to the main supporting structure. The tubular body is insertable, with its upper axial end, through an axial end of a tubular article in order to turn it inside out. The turning device comprises second actuation means which can be activated to rotate the tubular body about its own axis, through an angle of preset breadth, with respect to the main supporting structure.

摘要： A method for closing automatically an axial end of a tubular manufacture and for unloading it in inside-out configuration comprising a step of positioning the manufacture, in a right-way-out configuration, at a sewing or linking station, arranged so that its axis is substantially vertical and so that it hangs, by means of a first axial end to be closed by sewing or linking, from an annular handling device. Then a step is performed for inserting the manufacture, retained by the handling device, into an upper reversing tube that is or can be positioned, with its lower axial end, above the handling device. A step of closing the first axial end of the manufacture by sewing or linking is then performed. Then a step of disengaging the manufacture from the handling device and a step of removing the manufacture through the upper axial end of the upper reversing tube are performed.
