Abstract
A bobbin basket for use with a rotary loop-taker in a lock-stitch sewing machine is disclosed. The basket is integrally formed of plastic, with damage resistant members for reducing wear and impact damage at specified locations. The extent of each such location may be only a small fraction of the potential area of wear and damage. Inserts are disclosed for the needle thread stop, the needle thread pick-up notch, the upstream side wall of a rotation-restraining notch, the bearing rib, and the downstream side wall of the rotation-restraining notch.
