Abstract: The invention concerns a knitted-fabric garment in the shape of underpants, in which the crutch area is made up by a knitted-fabric prolongation without interruption with the rear part and folded up in order to be placed upon the front part of the garment body, forming there a front central panel. This front panel is fixed only at the outer points of a free end of the front part and at level with the waist-encircling edge, defining with the front part two side symmetrical openings, both communicating with a horizontal opening that comes out between the panel itself and the front-part free end. The invention concerns also a manufacturing method of the said garment.

Abstract: The invention concerns a method for manufacturing on circular knitting machines briefs without seams and having a front and rear parts joined by a infra-leg crutch area and shaped to define two side openings for legs and an opening at level with the waist-encircling portion The garment is manufactured starting from a first circular flat edge that defines a first opening for one leg, knitting a fabric in continuous tubular shape that defines contemporaneously the front part, the rear part and the crutch area of the garment, and finishing to a second circular flat edge that defines a second side opening for the other leg.

Abstract: The invention concerns a device for varying the length of stitches on circular hosiery and knitting machines, which includes means for rigidly anchoring the cylinder to the cylinder support, vertical guide means of the sinker bed with respect to the cylinder, and means for changing the height of the sinker bed to several positions between the two lowered and raised limit positions, in order to vary the level of the stitch formation plane defined by the sinkers in relation to the needles on the cylinder that remain in a fixed position. The invention involves also a circular knitting machine incorporating such a device.

Abstract: The invention concerns a method and a circular machine for manufacturing socks with closed toes with the use of picking-up means placed on several linked sectors, which are movable between an annular position corresponding to the cylinder with needles of the machine and a linear position on two parallel touching lines. The sock is picked-up from the cylinder by the pick-up means in the first position and transferred away from the machine, and while the machine can be restarted, the sock is turned upside down, the linked sectors supporting the pick-up means closed to form to parallel rows and the ends of the sock joined so as to close the toe.

Abstract: The invention concerns knitting and hosiery machines and in particular a system for detecting the presence of yarn being fed to the needles on the cylinder of such machines. Each yarn is fed to the needles through a yarn guide moving between an out of work to a work position and is associated with a sensor capable of detecting movement/presence of the yarn and to stop the machine when the yarn guide moves from the out of work to the work position and there is no movement/presence of the yarn.

Abstract: The invention concerns a method of producing a knit fabric which is patterned and at least partially plated, on a circular machine equipped with a cylinder with needles (12) and sinkers (14), comprising the use of a first strand and a second strand (A, B) which are different at least in colour and which are fed to the needles through the sinkers, and the positioning of the strands through selection and a programmed longitudinal movement of the sinkers in such a way as to arrange alternately, one or other of the two strands on the reverse side and face side of the resulting knit fabric, without cutting the strands, creating patterns which are different in colour at least, in the fabric areas in which there is, on the face side or in view, one or other of the strands. This method can be used both for the production of smooth plated fabric and for the production of fabric which is part terry and part plated.

Abstract: The invention relates to a double cylinder circular knitting machine which comprises at least one nozzle (18) providing a blast of air close to a yarn cutting-and-locking unit (13) to divert the ends of yarns cut and held by the said unit towards the interior of the cylinder, that is towards the reverse side of the item being manufactured. At the same time each cam (14, 21) for moving the needles where the yarns are picked up from the yarn guides is located and configured to move the needles at a predetermined distance from the yarn cutting-and-locking unit so as to leave a space for diverting the end (20) of the cut yarn towards the interior of the cylinder.

Abstract: The invention concerns a circular hosiery machine with vertical needles on the cylinder and horizontal needles in the bed plate for knitting terry fabric. Mono sinkers are inserted between the vertical needles on the cylinder, each having a hook for forming terry fabric stitches. The external diameter of the bed plate is noticeably reduced, at least in the area on a level with said hook of the sinkers to enable radial work movements of said sinkers without interference either with the bed plate or with the horizontal needles it carries.

Abstract: A method for selecting the needles in the production of a held stitch and a dropped stitch on circular stocking knitting machines, knitting machines and the like with one or more feed stations and selection units which operate the needles by use of jacks. The method includes prearranging two consecutive selection units (15, 16) in the feed station or in each feed station and using, starting from a condition of preventive extraction of all jacks with the respective needles lowered, one selection unit to control the needles that must knit the held stitch and the other selection unit to control the needles that must knit the dropped stitch.

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. The pipe with the summit bell is raised from the lowered position by dedicated control structure to raise the item, especially at areas closest to the needles.

Abstract: A method for making sponge-effect knitted fabric using needles on the roll of a circular machine for hosiery or knitwear which uses a skipped needle knitted fabric making procedure to selectively work an elastic or stretch thread and a non-elastic thread together or the one separately from the other. A manufactured product is also obtained with one or more designed parts made up of sponge-effect fabric of piles or loops in relief formed by selectively working one or the other of the two starting threads.

Abstract: The invention concerns an automatic and continuous measurement and control method of the tension and/or running of the yarns fed into knitting machines. It consists of permanently placing, along the route of each yarn towards the machine a device 15 for measuring the tension and/or running of the yarn, of connecting the devices to a management computer 16, programmed to recognise, display and process the reading data coming from each device and of the issuing by the computer of correction signals for the tension and/or running values of every yarn at every machine supply station and/or of the knitting in progress, when these values go beyond the prefixed limits.

Abstract: A method for making knitted articles incorporating parts similar to lace in a knitted article. Using the method the parts similar to lace are made directly on a knitwear or hosiery machine so they are integral and united with the remaining parts of the article. The method includes knitting selectively a first elastic or stretch thread and at least a second non-elastic thread wherein the position of the second non-elastic thread is reversed with respect to the needles fed according to a program.
