METHOD AND DEVICE TO MANUFACTURE STAPLE FIBRE FROM TWISTED SLIVER Russian patent published in 2011 - IPC D01G1/10 D02G1/20 

FIELD: textile, paper.

SUBSTANCE: separate slivers are laid next to each other to form a processed width of sliver and are jointly processed inside staple device. Prior to processing for giving twist, sliver is reduced from width of processed sliver into narrower width of twisted sliver, and after giving twist it is cut into staple fibres. To provide for the possibility to carry out optimised stages of processing with high volume of yield, according to invention, separate fibres inside width of processed sliver are sent into several partial slivers with equivalent values of partial width or with different values of partial width, which are combined into fibrous sliver with width of twisted sliver in the range from 700 mm to 1200 mm.

EFFECT: even though values of processed sliver width are significant, it is possible to combine separate slivers from only a few layers into a sliver with appropriate insignificant deviation of fibre strands.
