Claims8
In a travelling wave shedding loom, a plurality of shuttles, and a device for winding and loading shuttle bobbins of the loom, said device comprising a movable support member associated with each shuttle and movable with the shuttle, chain carriages with selection means and wrap control cams, said carriages advancing with the shuttles, said movable support members being supported by the carriages a winding-loading mechanism and means for mounting a storage spool carried by each support member, means for withdrawing metered quantities of weft yarn from each storage spool and for forming one respective bobbin per shuttle on the respective winding-loading mechanism during delivery of successive wefts from a preceding bobbin, and means for effecting transfer of the bobbin from the mechanism to the respective shuttle.
