DETAILED DESCRIPTION OF THE INVENTION

(4) In this detailed description, preferred embodiments of the yarn spinning system (50) of the invention are explained for better understanding of the subject and not causing any limiting effect.

(5) The main material used for yarn formation is fed into the system via sliver feeding part (20). The draft area (A) and the suction areas are within the main spinning unit (40). The suction pipes (41) in said main spinning unit (40) enable the intake of waste fiber formed during the spinning. Orderly drawing and smoothing of the main material (fiber) fed into the system is carried out with the draft cylinders (44). Said components constituted the yarn spinning system (50). The injected yarns (13) to be fed into said main spinning unit (40) are wound around the bobbins (12). Tension of said injected yarns (13) is enabled with the yarn feeding bar (31). The injected yarn (13) is conveyed to the draft area (A) through the yarn feeding path (32) on the yarn feeding bar (31). Said yarn spinning system (50) comprises the yarn guide (43) providing the conveyance of the injected yarns (13) to the main spinning unit (40) by being centered on the main material.

(6) Structure Principle is as Follows:

(7) FIG. 1 is perspective view of the empty situation of the air-jet yarn production system (50) of the invention.

(8) Said yarn spinning system (50) consists of the creel (10), the sliver feeding part (20), the yarn feeding part (30), the main spinning unit (40) parts.

(9) Said creel (10) consists of the creel hanger (11), the bobbin (12) and the injected yarns (13). The injected yarns (13) are wound to the bobbins (12), in turn the bobbins (12) are hung on the creel hangers (11). The injected yarns (13) are wound around the bobbins. Said injected yarns (13) are yarn having different features such as color, structure etc. in accordance with the fancy yarn type to be produced.

(10) The main material to be subjected to the spinning procedure is a group of fibers as short fibres. This main material will be turned into yarn via the spinning procedure.

(11) The sliver feeding part (20) is the part into which fibers in sliver form as the main material subjected to the spinning procedure are fed. The fibers here are conveyed into the system by passing through the sliver feeding guides (21) mounted on the sliver feeding bar (22).

(12) The yarn feeding part (30) is the part into which the injected yarns (13) to provide fancy yarn appearance are fed. This part consists of the yarn feeding bar (31) and the yarn feeding path (32).

(13) Lastly, the main spinning unit (40) in which the spinning procedure is performed consists of the suction pipes (41), the cover (42), the yarn guide (43), the draft cylinders (44), the sleeves (45) and upper apron (46) components. Said suction pipe (41) is the component enabling the intake of the waster fiber formed during the spinning.

(14) The cover (42) is used to prevent situations such as impact etc. coming to this section from outside and to provide a cleaning working environment by covering the main spinning unit (40).

(15) The yarn guide (43) is the guide components enabling complete centering of the fed injected yarns (13) on the main material.

(16) The draft cylinders (44) as another component enable drawing, smoothing and thinning of the fiber orderly. The sleeves (45) positioned on said draft cylinders (44) enables a proper fiber draft by putting pressure on the fiber.

(17) There is the upper apron (46) on the last part of the main spinning unit (40). Said upper apron (46) enabled the dispatch to the other parts in which fibers are twisted.

(18) Assembly Principle is as Follows:

(19) The main spinning unit (40) is positioned on upper part of the yarn spinning machine. 4 draft cylinders (44) are lined to the lower portion of the main spinning unit (40) side by side with predetermined intervals. The sleeves (45) are placed on upper portion of each draft cylinder (44). Said draft cylinders (44) and the sleeves (45) constitute the draft area (A). The upper apron (46) is put on the 3.sup.rd draft cylinder (44) from the start and the sleeve (45) thereby enabling orderly dispatch of the fibers.

(20) The cover (42) is positioned on said components, thus enabling the realization of the spinning procedure in a covered environment. The suction pipes (41) are mounted on the cover (42), thereby providing the connection of the cover with the inner portion of the main spinning unit (40).

(21) The creel (10) system is arranged on upper side of the system. The creel (10) system is mounted such that there are two creel hangers (11) on the top of each main spinning unit (40). The bobbins (12) to which the injected yarns (13) are wound are hung to these creel hangers (11). The yarn feeding part (30) is positioned to the front side of the creel (10).

(22) The main spinning unit (40) also comprises the yarn guides (43) by which the injected yarns (13) are to be incorporated to the system. Said yarn guides (43) are placed on the top of the draft cylinders (44). Moreover, sensor (23) is configured in the system, and the injected yarn (13) enabled the controlled feeding of the injected yarn (13) during the spinning by passing through the sensors (23). When the injected yarn (13) breaks and/or no yarn is left on the bobbin, the spinning box is stopped and a light is turned on and thusly, intervention of an operator is enabled.

(23) Working Principle is as Follows:

(24) The main material in sliver form in the yarn spinning system (50) mounted as described above is conveyed to the draft area (40) passing from the sliver feeding guide (21) on the sliver feeding bar (22).

(25) The main material is prepared to enter into the main spinning unit (40) with draft and thinning procedures between the draft cylinders (44) and the sleeves (45).

(26) As the main material is prepared as such, the injected yarns (13) in form of bobbins (12) to be injected (different number, color, material and/or yarns twisted using technologies) are placed on the creel hanger (11). Feeding to the yarn guide (43) is provided passing through the yarn feeding bar (31) and the yarn feeding path (32). The yarn feeding path (32) and the yarn feeding guide (43) are profoundly important in terms of working performance of the yarns and the appearance of the effect. These are crucial parts for the ability to make compatible centering (Compatible centering: feeding of the injected yarn (13) on the main material in accordance with desired effect shape). The injected yarn (13) is sent to the main spinning unit (40) with the main material with the aid of the sleeves (45) and the upper apron (46).

(27) During all these stated processes, air-jet fancy yarns may be produced with the materials prepared by way of the feeding of different materials in desired ratios and desired appearance effects (depending on the efficacy of centering and dispatch guides) into the main material.
