Abstract
A device for weft insertion has a weft guide channel defined by a number of reed teeth or weft yarn guide members arranged in juxtaposition to the reed, and at least two main nozzles that are used selectively for weft insertion. At least one weft-inserting main nozzle adapted to project the weft yarn towards the weft yarn guide channel has its fluid jet opening directed parallel to the longitudinal axis of the weft guide channel, the other weft-inserting main nozzles having their jet axes inclined with respect to the longitudinal axis of the weft yarn guide channel and directed both downstream of the channel and towards the recessed wall surface opposite to the open side of the channel.
