IPC: B65H65/00
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To inexpensively make a device into an equipment and to suppress failure frequencies of the whole of the device to a small degree by supporting a plurality of filament yarn packages so that each center shaft may be substantially parallel and fixing filament yarn tip parts on the side of an external layer and on the side of an internal layer of filament yarn packages to prescribed locations. SOLUTION: Filament yarn tip parts on the sides of external layers and the sides of internal layers of filament yarn packages 2 supported so that center shafts may be substantially parallel are fixed to prescribed locations by fixing means 5. Because the fixing means 5 are required to only move to locations of desired filament yarn packages to be treated 2, complicated moving control mechanisms are unnecessary. Because it is allowable that the number of fixing means 5 is smaller than the total number of the filament yarn packages to be treated 2 and the number of the fixing means 5 can be remarkably reduced, the whole of a device can be inexpensively constituted. Failure frequencies caused by these fixing means 5 can be remarkably reduced by a small number of the fixing means 5 and stable working for a long period is made possible.
