Abstract (en)
[origin: DE10251727A1] In a process to prepare slubbing for a textile ring spinning machine, a drawing frame sliver is fed to drafting rollers and then twisted before it is wound onto a spool prior to use. The fiber (F) discharged from the drafting rollers is fed to a first pneumatic twist chamber (1) with a passage (11) in which the air rotates in the opposite direction to that in a second pneumatic twist chamber (2). Prior to its surrender to the first twist chamber (1) the fibers (F) are separated into peripheral fibers (FR) with loose ends and twisted fibers (FD). In the first chamber the loose ends of the peripheral fibers (FR) are twisted in the opposite direction to those of the twisted fibers (FD). Also claimed is a commensurate twisting assembly and a take-up reel and winder for the finished slubbing fiber. The drawing frame esp. has no fiber compressor located prior to the drawing frame outlet. The drawing frame discharges esp. to first and second twist chambers.
