Cloth edge curl correction device

A cloth edge curl correction device that is equipped in a sewing machine provided with a turn-back guide device arranged in front of a needle location position on a sewing machine bed, then folding up and down over a given width an edge part of a cloth to be fed to the needle location position, and then feeding the cloth to the needle location position and that corrects a curl generated in the edge of the cloth to be fed into the turn-back guide device, comprising:

• a support plate extending along a direction of feed of the cloth at a front position of the turn-back guide device;
• a cloth support provided near the support plate and supporting the cloth from the under;
• and
• an air ejection nozzle ejecting air toward a base part of the cloth support;
• wherein ejected air from the air ejection nozzle is applied to the edge of the cloth on the cloth support so that a curl generated in the edge is smoothed and corrected and then the cloth is fed in a manner that the edge goes along the support plate, and
• the support plate is attached in a manner of permitting position adjustment in the right and left directions at a front position of the sewing machine bed,
• further comprising:
• a support rod adjusting a position of the support plate in the right and left directions.

• further comprising:
• a second air ejection nozzle arranged in front of the air ejection nozzle and ejecting air toward the edge of the cloth prior to reaching the support plate so as to preparatorily correct a curl generated in the edge;
• and
• a turn-up member arranged at a front position of the cloth support in a manner of permitting position adjustment in the right and left directions and turning up the edge of the cloth extended by the ejected air from the second air ejection nozzle.
