摘要:
A method and mechanism for free form sewing in which the workpiece is being sewn on a sewing machine having a plastic sheet or panel secured to the sewing machine work surface which has a coefficient of friction in any of several ranges which are all considered to be low friction coefficients. Depending upon the plastic material used, the coefficient of friction of any particular material may be in the range of 0.02 to 0.20, or in smaller ranges of coefficients of friction. The objective in using the method or mechanism is to permit the workpiece being sewn by free form sewing to be moved more easily with less frictional resistance by the hands of the sewing machine operator. Various plastics usable include various types of Teflon.

A bobbin basket for use with a lock-stitch sewing machine. The bobbin basket defines a receptacle for a thread-carrying bobbin case. The bobbin basket has a wall extending around a central axis and a rib projecting radially from the wall for reception in a raceway of a rotary loop taker, to which the bobbin basket can be operably connected. The bobbin basket is molded from a TORLONnull-based material commercially sold under the designation PXM01017.
