Abstract:
A pre-spooling device for temporarily storing a weft thread for an air jet loom, said device comprising:a weft thread storage drum, which comprises a plurality of drum segments that are each movably adjustable in a radial direction relative to a center axis of said drum, and which has an upstream end and opposite thereto a downstream end; a rotationally drivable drive shaft; a thread winding guide which is arranged adjacent to said upstream end of said drum, connected to said drive shaft so as to rotate therewith, and adapted and arranged to wind the weft thread onto said drum segments of said drum; a drawing-off eyelet arranged adjacent to said downstream end of said drum and adapted to have the weft thread drawn-off from said drum segments through said eyelet and to the loom; and a protective disk, which is arranged between said downstream end of said drum and said drawing-off eyelet, and is so configured and adapted so that the weft thread is drawn over a circumferential edge of said protective disk when the weft thread is drawn-off from said drum segments to said drawing-off eyelet; wherein said pre-spooling device has plural non-rotating components, including said drum which is a non-rotating drum; and wherein said protective disk is rotatably connected to at least one of said non-rotating components so as to be rotatable about a disk axis coincident with said center axis of said drum.
