VERSIONS OF CARBON FIBRE PACKAGE AND VERSIONS OF METHODS OF WINDING SAID PACKAGE Russian patent published in 2011 - IPC B65H55/04 

FIELD: chemistry.

SUBSTANCE: package is obtained by winding a bundle of carbon fibre on a holder. The carbon fibre for versions of the package and for versions of the method has fineness between 25000 denier and 35000 denier. The width per unit fineness of the bundle of carbon fibre in the holder for versions of the package and versions of the method lies between 0.30×10^-3 mm/denier and 0.63×10^-3 mm/denier. The winding angle at the beginning of winding for versions of the package and versions of the method ranges from 13° to 14° and from 10° to 11°. The winding angle at the end of winding for versions of the package and versions of the method is equal to 3° or more, 2° of more and 5° or more. The fraction W0 of the winding pitch W for versions of the package and versions of the method ranges from 0.07 to 0.08, from 0.90 to 0.91, from 0.09 to 0.10 and from 0.92 to 0.93.

EFFECT: obtaining package with improved winding density owing to selection of an optimum range of width per unit fineness of the bundle of carbon fibre and an optimum winding angle at the beginning and end of winding.
