ABSTRACT:
An apparatus for entwining the fibers of slivers of stretch break-conversion machines, cut-conversion machines, carding operations, drawing operations, etc., with the slivers including individual fibers that are initially disposed essentially parallel to one another. To improve the cohesion of the fiber slivers, and to make it possible to transport and further process the slivers without difficulty, and without limiting the range of application of the previously advantageous conventional processes, it is proposed to convert the fiber sliver into a sliver having an essentially flat shape, to deflect a portion of the fibers of the sliver from their parallel orientation, and to further deflect the already deflected fibers in the direction that is essentially perpendicular to these fibers, with this further deflecting step effecting entwining of the deflected fibers with those fibers that are still disposed in the parallel orientation.
