Abstract
According to the method, an end part of a roving is first introduced into the main drafting zone of a drafting frame of a textile machine after a reference point at a clamping device. Thereafter, a middle part of the roving is drawn laterally into the preliminary drafting zone solely by the tension of the main drafting zone. The apparatus comprises a gripper which is connected via a pivotable arm or a telescopic arm to a mobile or stationary robot which can cooperate either with a pusher, a spacer or a fixed slider.
