Loom weft insertion - shuttle has recess for single pick weft, inlet guide has barb

In a shuttle in which a single pick is wound on to a bobbin rotatably mounted in a recess, for paying out as the shuttle passes through the shed, a guide member for guiding the yarn on to the bobbon during winding before the shuttle is travelled comprises a groove in a plane perpendicular to the disc-like bobbin axis, connected to an inlet groove, perpendicular and opening into the face of the shuttle, there being a barb-like member between the two grooves to prevent the thread passing back into the inlet groove.
