Abstract
In an apparatus for selecting and feeding wefts to an insertion device of a weaving machine, the feeders are directly connected to eccentric drives which have an excursion corresponding at least to the paths covered by the feeders between their rest and feed positions, and each feeder is associated with a guide and arranged to compensate for transverse displacements of the eccentric drives which deviate from the reciprocating motions of the feeders. The feeders have an excursion corresponding to at least the distance between the rest and feed positions of the feeder, with each feeder together with a drive motor, the eccentric drive, and the guide forming a module to simplify matching of yarn feeders to the requirements of a specific fabric and exchange of units in case of a defect. Advantageously, the modules of neighboring feeders may be mounted in mirror-symmetric manner relative to a common plane in which all of the feeders are mounted. The drive motor is preferably connected to a control unit arranged to control the drive motor to position the feeder at a position intermediate between the rest and the feed positions and selected in such a manner that the weft is deflected as little as possible by the feeder when being inserted.
