1. Method for automatically producing three-dimensional tubular knitwear items, in circular knitting machines provided with at least a cylindrical needlebed (CYL), characterised in that it comprises the steps of:inactivating and excluding from the knitting process at least a predetermined number of adjacent needles (A) of the needlebed (CYL), chosen in at least a defined knit area of the needlebed (CYL), for a predetermined time interval and producing, with the remaining working needles (A) of the needlebed (CYL) and with the continuous motion of the needlebed (CYL), a first length of tubular knitted fabric (1) having an annular shape and having a plurality of floating yarns (FF) in a zone of the knitted item (1) corresponding to said defined area of the needlebed (CYL), said zone of the knitted item (1) being provided to constitute a zone of the final knitted item (1) characterized by the presence of said floating yarns (FF) having aesthetic and/or functional purposes. 2. Method according to claim 1 characterised in that at least a part of said predetermined number of needles (A) is inactivated automatically and progressively.3. Method according to claim 1 characterised in that it further comprises, before said step of inactivating and excluding from the knitting process at least a predetermined number of adjacent needles (A), the step of producing a second length of tubular knitted fabric (1), said predetermined number of needles (A) completely releasing and discharging the corresponding loops of the knitted fabric (1) during said step of inactivating and excluding from the knitting process said predetermined number of adjacent needles (A), whereby at least an opening (H) is produced between said second length and said first length of the knitted item (1), in a zone corresponding to said defined knit area.4. Method according to claim 1 characterised in that it further comprises the steps of reintroducing said predetermined number of needles (A) in the knitting process after said predetermined time interval corresponding to a plurality of stitch courses, by an automatic and programmed resumption of knitting on said predetermined number of needles (A), and producing, after said first length of knitted fabric (1), a third length of tubular knitted fabric (1).5. Method according to claim 1 characterised in that it further comprises the step of cutting said floating yarns (FF), in a phase subsequent to the knitting process of the knitted item (1), to obtain in said zone of the knitted item an opening (H) with fabric edges provided with fringes of variable length.6. Method according to claim 3 characterised in that it further comprises the steps of:reintroducing said predetermined number of needles (A) in the knitting process immediately after said step of inactivating and excluding from the knitting process at least a predetermined number of adjacent needles (A) of the needlebed (CYL), by an automatic and programmed resumption of knitting on said predetermined number of needles (A), and resuming the knitting process with both the excluded needles (A) and the remaining needles (A) and producing a third length of tubular knitted fabric (1), thus providing at least an opening (H) in the knitted item (1) between said second and said third length of knitted fabric (1), in said defined area of the needlebed (CYL) corresponding to the excluded needles (A), with a controlled partial separation of two theoretically consecutive stitch courses. 7. Method according to claim 6 characterised in that the dimension of said defined knit area is determined in order to obtain an opening (H) defining in said item at least a fabric stripe, loop, shoulder strap or brace.8. Method according to claim 3, further comprising the step of providing said shoulder straps, braces and/or openings (H) with hemmed fabric and with at least a single or double layer welt (BD), said welt being produced with the needles (A) of the cylindrical needlebed (CYL) and by means of a second needlebed or dial.9. Method according to claim 3, further comprising the step of providing said shoulder straps, braces and/or openings (H) with hemmed fabric and with at least a single or double layer welt (BD), said welt being produced with the needles (A) of the cylindrical needlebed (CYL) by producing inner frills (Bi) with a fixed and prolonged selection of alternated needles (A).10. Method according to claim 4 characterised in that at least a part of said predetermined number of needles (A) is reintroduced in the knitting process progressively.11. Method according to claim 1 characterised in that said predetermined number of needles (A) excluded from the knitting process are chosen in at least two defined and separate knit areas of the needlebed (CYL).12. Method according to claim 1 in which said step of inactivating and excluding from the knitting process at least a predetermined number of adjacent needles (A) of the needlebed (CYL) comprises the steps of interrupting the knitting process with all the needles (A) of the needlebed (CYL) in non-working position and all the yarn-feeders excluded and releasing the loops of the knitted fabric (1) engaged to said predetermined number of excluded needles (A), while the remaining needles (A) of the needlebed (CYL) retain their loops of knitted fabric (1).13. Method according to claim 1, comprising providing automatically said items with one or more shoulder straps, loops, braces and/or holes (H), eyelets and/or floating yarns (FF), operating with the continuous motion of the needle cylinder and by the temporary and gradual interruption of the knitting process for a group of preferably adjacent needles (A), in definite fabric areas, less than 360°, followed by the automatic and gradual re-start of the knitting process, preferably with the same needles (A) or in the same definite fabric areas, after the intervention of mechanical or pneumatic elements working as latch-opening devices (AL) for the controlled separation of two knitted courses which are theoretically consecutive and also partially overlapping; said courses being characterised in that one of them represents the last course of knitted fabric (1) and the other one the first course produced after said interruption, said openings (1) and/or loops being obtained without cutting and sewing operations.14. Method according to claim 13 for producing tubular items which can also be shaped or fitted, provided with one or more holes or openings (H) which can also be very broad, automatically produced by the appropriate selection, presence and absence of the elements directly or indirectly involved in the knitting process, such as jacks, needles (A), under-needles (A) and fabric sinkers (PM).15. Method according to claim 1 characterised in that it comprises the steps of providing automatically said tubular items with one or more fabric rings, loops or half-rings at least partially connected with the manufactured item (1), and introducing or connecting at least partially said fabric rings in at least a hole or other opening (H) of the manufactured item (1).16. Method according to claim 1 characterised in that it comprises the steps of providing automatically said tubular items with one or more fabric rings, loops or half-rings at least partially connected with the manufactured item (1), and introducing or connecting at least partially said fabric rings in at least a hole or other opening (H) of another knitted article or textile manufactured item (21).17. Method according to claim 1 comprising producing in said tubular items an anatomically shaped portion and a substantially naked portion having wide apertures alternated to suitable fabric swipes, preferably provided with single or double hems or welts (DB).18. Method according to claim 7 characterised in that at least a portion of said fabric stripes (11,51) is produced with a plurality of floating yarns (FF).19. Method according to claim 7 further comprising the steps of cutting said fabric stripes or loops and preferably subsequently knotting said stripes.20. Method according to claim 1 further comprising the step of producing automatically in said items (1) at least a zone (SA) of lighter and more transparent fabric, by knitting the item (1) with a substantially reduced number of needles (A).21. Method according to claim 1 for producing compound knitted items, further comprising the step of connecting structurally and functionally at least two knitted items (1, 21) one to the other, by means of connection means such as stripes, strings or half-rings.22. Method according to claim 1 characterised in that the knitting process of the excluded needles (A) is preceded by the intervention of latch-opening devices (AL) and starts again only with selected needles (A) always following an alternated order, in at least a feed provided with yarn.23. Method according to claim 3 characterised in that the discharge of the stitches from part of the needles (A) is anticipated by one or more knitted courses, which can also consist of tuck stitches and/or welts, preferably with the introduction of at least a additional yarn, which can also be elastomeric and/or thermo-adhesive.24. Method according to claim 3, characterised in that the discharge of the stitches from part of the needles (A) takes places by totally lowering said needles (A) without the new yarn, under the pulling-down plane of the sinkers (PM), synchronously with the radial removal of the latter.
