ABSTRACT:
This invention concerns a sewing machine of the kind in which a main base and a supplemental base are provided. The supplemental base is connected to the main base through link mechanisms so as to be either contiguously positioned with respect to the main base or spaced therefrom so as to present a narrower support surface conducive to supporting a tubular fabric.
