ABSTRACT:
A stop control for a sewing machine having an attachment for the making of spaghetti-like tubes, without visible stitching, and with or without a core filler, from a supplied bias binding material, the binding material being comprised of elongate strips joined in end-to-end relation by end connecting seams in which the connected free ends of the strips are disposed on the same side. The strip is fed to the attachment through a switching device in an electric control circuit which is energizable by contacts of the switching device and operable to terminate the operation of the sewing machine upon the occurance of a predetermined condition with respect to the binding strip material, such as: (1) a binding strip connecting end seam is too thick, (2) the binding strip becomes knotted or twisted, and, (3) the supplied binding strip material breaks or runs out.
