In wet-drafting an assembly of staple fibers, said assembly is drafted directly after wetting in at least two coupled drafting zones, producing together at least a 100-fold elongation. The drafting system is provided with compensating means (belt, guide and air blower) to prevent sticking of the fibers to the rollers of the drafting system and with means to control the amount of liquid between the staple fibers.
