ABSTRACT:
The device for increasing the cohesion length of the slivers is embodied by a pair of calendar rollers. Each calendar roller has a plurality of transversely disposed protuberances of rounded shape for interengaging in spaced relation with each other in order to slightly crimp a sliver passing through the gap between the rollers. The protuberances are adapted to one another in gear-like manner.
