Abstract
An axis of a needle is inclined with respect to an imaginary plane perpendicular to an axis of a lower shaft. The lowermost position of the needle where it comes closest to a loop taker is spaced from the loop taker in the axial direction thereof in proportion to the degree of inclination of the axis of the needle. As a result, the length of a bobbin accommodated in the loop taker can be extended along the axis thereof, thereby permitting the amount of thread loaded on the bobbin to be increased. The amount of thread drawn by a needle thread take-up may remain the same and need not be changed.
