`machines can be divided into models for knitting stitch-shaped garment-
`length pieces and models for knitting fabric in the roll as yard goods.

`
`Small-diameter circular machines having a single cylinder and one set
`of latch needles are usually used for knitting fine-gauge ladies‘
`legwear or, when equipped with two superimposed cylinders and one set
`of double-headed latch needles, for knitting socks,
`three-quarter hose
`and half-hose. Fine-gauge automatic single-cylinder machines in this
`range are able to knit complete ladies’ tights, often with a toe closed
`on the knitting machine and with elasticated threads knitted into the
`waist section of the garment. After such tights have left the knitting
`machine,
`they are merely dyed and heat-set, when they are ready for
`packaging and sale. Double-cylinder legwear machines,
`too, are able,
`in some instances,
`to produce garments with the toe closed on the
`double-cylinder machine.

`
`Large-diameter circular knitting machines are used for producing fabric
`as yard goods for outerwear, sportswear and so on, and also for producing
`body-width garment
`lengths for, for instance, underwear garments without
`side seams. Large-diameter circular knitting machines with jacquard
`installations use a variety of jacquard mechanisms such as pattern
`levers, pattern wheels and pattern discs, steel tapes and drums, and
`such electronic pattern installations as film strips, magnetic tapes
`and magnetic plates for carrying the patterning data.
`The electronic
`patterning facilities frequently permit
`the production of almost
`unlimited pattern areas right up to the full circumference of the
`needle cylinder (about 1.5 m fabric width) and extending over the full
`length, of, for instance, a lady's dress. Connected to these electronic
`patterning installations are electronically operating pattern-preparation
`units where the design can be projected on a television screen and
`transferred very quickly to the knitting machine either manually or
`automatically.
`By exchanging yarn colours and cancelling a particular
`colour without having to change yarn packages, it is possible to develop
`mirror effects, extensions in the height and width of the pattern and
`other variations of the design, by just pressing a button.

`This includes a large-diameter circular knitting machine for producing
`imitation-fur fabrics.
`The machine has attachments for feeding slivers
`of fibres to the needles.
`The latest machines in this range are fitted
`with electronically operating needle-selection units,
`thus making it
`possible to produce complete imitation animal pelts.
`
`Another machine in this group, which has a special inlay installation
`and makes economic use of pile yarn, can be used to produce floorcover-

`Automatic cylinder and dial machines for knitting rib fabrics and super-
`imposed double-cylinder machines for knitting purl fabrics are available
`both in body-width diameters and in 33-inch diameters for knitting
`stitch-shaped garment
`lengths for ladies‘ underwear, pullovers and
`shirts with a firm non-roving rib bottom or tubular welt.

`These are special machines where knitting takes place only round roughly
`four-fifths of the circumference of the needle cylinder. This produces
`flat pieces of fabric, which are knitted both with regard to length and
`width in accordance with pre-determined dimensions.
`These semi-fashioned
`pieces of fabric resemble the product of the flat knitting machine.

`Only a few of these machines are in existence at the present time.
`threads for forming the fabric are supplied from two concentrically
`arranged sets of sectional warp beams, with each circle of warp beams
`moving in opposite direction to the other. This arrangment of warp-beam
`movement produces thread-crossing over the latch needles in the machine
`for a milanese fabric with open laps (double atlas fabric without
`turn-
`round courses).

`The long frame of the machine is sub-divided into sections by a number
`of dividing walls.
`The two outer sections of the machine, and on
`machines which have many knitting heads,
`the centre section,

`accommodate the central control installation of the machine.
