Abstract (en)
[origin: EP0375242A2] A process and apparatus for the production of roving uses vacuum spinning techniques. Specifically, a fibre mass, or sliver (S), is drafted through a drafting zone (14) and passed into a hollow, rotatable shaft (26), the shaft having a central through passageway (31) and a plurality of radially oriented orifices (38). The shaft (26) is mounted in a housing (24) to which a vacuum is applied as the fibre mass passes through the rotating shaft. Trailing free ends of a minor portion of the fibres are pulled into the orifices (38) and, as the linear movement of the fibres continues, are pulled back out of the orifices and are wrapped about the remaining core fibres to form a roving.
