Sewing machine - has equipment adapted to control supply of endless cord or wire which is stitched into position

摘要

A sewing machine has a supply of material in string form fed to the stitch position from a revolving swift. An arm attached to the machine has a bar suspended in the manner of a pendulum. A spindle protrudes through the bar to support a swift on each side. Against the rim of the swift a pad presses towards cross- bars fixed in a support bracket which act as material guides. ADVANTAGE - The material fed to the sewing machine may be cord or copper wire cable, applied by zig-zag stitch to technical cloths. The regulation enables straight sides to be machined rapidly, with slower movement on curves, etc. releasing the cord evenly
