Pressing device for material to be sewn



PURPOSE: To provide a material pressing device which can suppress generation of puckering as much as practicable. CONSTITUTION: This pressing device for material to be sewn is composed of a throat plate and a cloth holder A having an aux. holder 3 energized in such a way as protruding slightly into a feed cog groove in the throat plate from the undersurface of a holder foot 1. For sewing a thicker material, a chamfer is formed on both sides of the upper part of the feed cog groove of throat plate confronting the aux. holder 3. A part of foot 1 at least farther than the needle drop position is warped upward so that the cloth feeding motions are made the most of.
