ABSTRACT:
A method and apparatus for disposing an end of roving of a roving bobbin at a disposing location adjacent the drafting device of a spinning station of a textile spinning machine The roving end disposing apparatus, which is preferably mounted on a traveling service unit which travels to the spinning stations of the textile spinning machine to perform roving feed start operations thereat in which the feed of roving from a roving bobbin through a drafting device is started, includes a roving end support assembly for supporting a roving end for movement between a receipt location at which the assembly receives the roving end and the disposing location adjacent the drafting device at which the supported roving end is released either for engagement by the drafting device or piecing of the roving end with roving extending from another roving bobbin through the drafting device. The roving end disposing apparatus also includes a component for directing air against the roving end in correspondence with its release from the support assembly to facilitate movement of the roving end at an inclined direction into position for engagement by the drafting device or piecing with another roving. The air directing component preferably includes an air jet and an air source reversibly operable to apply suction through the air jet to secure the roving end during movement between the receipt location and the disposing location and to supply pressurized air against the roving end.
