Abstract
In the threading of roving coming from a roving bobbin into a running set of drafting rolls of a work station of a spinning machine, the beginning end of the roving coming from the roving bobbin is grasped and brought into the set of drafting rolls bypassing at least the first (upstream-most) pair of rolls and is delivered to the drafting rolls downstream thereof. Only then is the roving fed into the set of drafting rolls bypassing at least the first pair of rolls inserted laterally in the preceding (bypassed) roll pair or pairs from a side of the free or unjournaled end of the upper roll.
