Computer-controlled, High-speed, Bartacking Machine for Eyelet Buttonholes
The machine is provided with a material-drawing mechanism which draws the right and left parallel portions of an eyelet buttonhole near to one another. The machine performs bartacking with the right and left parallel portions of the eyelet buttonhole drawn near to one another after the buttonhole is clamped under the work clamp foot, thereby finishing highly durable and well-tensed eyelet buttonholes.
