ABSTRACT OF THE DISCLOSURE An improved spinning method and its apparatus utilizing pneumatics and centrifugal force. The bundle of fibers delivered from a supply source is shredded in a supply conduit of the feeding means by a fluid stream caused by compressed air, and the shredded fibers are deposited continuously on a rotating receiving surface of a rotor and cohered on the receiving surface, then the cohered fibers in a circular bundle form are displaced to a collecting surface having larger radius than the receiving surface by the centrifugal force caused by the high speed rotation of the rotor and a continuous bundle of fibers is taken off from the collecting surface and drawn out from the outlet of the rotor while turning the bundle of fibers by the twisting action of the rotor, and thereafter the twisted bundle of fibers, that is the produced yarn, is packaged by a suitable winding mechanism. To control the above-mentioned twisting, certain twist control means attached to the rotor are provided.
The present invention relates to an improved spinning method and apparatus for manufacturing yarn from textile fibers, more particularly relates to a practical spinning method and apparatus utilizing pneumatics and centrifugal force suitable for mass-production.
Many proposals have been made on the open-end type spinning system. As it has been clearly shown by the process of open-end spinning system as disclosed in Czechoslovakian Pat. No. 91,208 issued in 1958, that generally the system is characterized by separating the twisting and the taking-up operations. Aftershredding the continuous structure composed of numerous fibrous materials, they are bundled again to form a new continuous structure by means of a rotating member for accumulating the individual fibers and twisting this structure.
Among these prior open-end spinning systems, a spinning method, wherein the shredded individual fibers of the bundle of fibers are conveyed onto the inside wall of the spinning rotor by utilizing suction air, and taken out through an aperture disposed to the central bottom portion of the spinning rotor, while providing twisting operation, is well known. But this method has many drawbacks such as large power consumption, inferior quality of the yarn produced, limitation in spinning speed caused by the mechanical features of this spinning system, high degree of twisting required for preventing yarn breakage and the difiiculty in manual operation required at the time of starting the machine. Consequently, it is still difficult to utilize the prior type of open-end spinning method in a practical production process.
The principal object of the present invention is to provide an improved spinning method and apparatus utiliz- 29 Claims ice ing pneumatics and centrifugal force which are accompanied by high production speed and stable spinning condition for eliminating the above-mentioned drawbacks of the prior open-end spinning methods.
Another object of the present invention is to provide an improved spinning method and apparatus which can produce improved quality of yarns at high production speed and stable spinning condition by controlling the tension and the twist of the spinning yarns.
Still another object of the present invention is to provide a spinning rotor which can produce yarns having superior properties, beautiful appearance and high bundling property in the spinning method and apparatus wherein pneumatics and centrifugal force are utilized.
A further object of the present invention is to provide a method of yarns which can produce yarns of superior qualities under a wide range of spinning conditions with simple mechanisms and small power consumption in the spinning method and apparatus wherein pneumatics and centrifugal force are utilized.
Further features and advantages of the present invention will be apparent from the ensuing description with reference to the accompanying drawings to which however the scope of the invention is no way limited.
