PURPOSE:To eliminating necessity for replacement of holder when bobbins with different taper are to be used, by making the fixing position for a bobbin supporting member of a bobbin holder device possible with rotary adjustment in correspondence with inclination of the bobbin holder on the basis of change of the taper of bobbins. CONSTITUTION:A bobbin supporting member 67 to support a bobbin 8 exhausted from a bobbin outlet at the outside surface is mounted adjustably with respect to the mounting surface 66 through a mount piece 68 projecting at the rear surface. In case bobbins 8 with different taper are to be used, a bobbin holder 9 is rotated on the mounting surface 9a and fixed in the specified position. Then screws 71 fastening the mount piece 68 of the bobbin supporting member 67 to a mount bracket 61 are loosened, and the mount piece 68 is turned round a through hole 70 along a long hole 69 till a position, in which inclination of the bobbin supporting member 67 is in correspondence to that of the bobbin holder 9, and fixed there by the screws 71. According to this arrangement, there is no need to replace the holder part even though bobbins with different taper are to be used. |
