Frame structure for a blindstitch hemming machine

Image Number 3 for United States Patent #4372234.

A machine forming stitches invisible on one work face, with curved needle, looper, work feed, and associated drive mechanisms arranged beneath the work. After convenient assembly of these mechanisms on bosses rising from a frame base, a frame cover is attached carrying a presser and a device for forming a work ridge in the needle path. A compartment extending across this machine front is formed within the frame to accommodate the needle thread supply and controls.
