Abstract
Weft yarn is inserted into the weaving rotor of a series shed weaving machine. Four weft yarns (7; 71, 72, 73, 74) are conveyed into the weft yarn distribution apparatus (9) from four supply units (2a-2d) and four metering apparatuses (1a-1d). The weft yarn distribution apparatus (9) distributes the weft yarns (71-74) delivered to it to the sheds of the weaving rotor (100) which are currently open, with the weft yarns being inserted through stationary fluid nozzles (91, 92, 93, 94) into the rotating weaving rotor (100). During normal operation of the series shed weaving machine, the weft yarn (71-74) is continuously pulled from the weft yarn supply (2a-2d) by the metering apparatuses (1a-1d) and conveyed to the weft yarn distribution apparatus (9) which conducts the weft yarn (71-74) into an opened shed (103a-103d). The speed of conveyance of the weft yarn (71-74) during insertion into the shed (103a-103d) is thus determined by the metering apparatus (1a-1d).
