ABSTRACT:
A ruffler attachment for a sewing machine, the operation of which is synchronized with the main sewing machine driving mechanisms, and facilitates adjustment of the size of the ruffle, and the number of ruffles to be formed, is provided. The ruffler attachment is characterized by a stiffener blade disposed to permit a body material to be introduced thereunder into the sewing displacement position of the needle to effect sewing of the body material. A feeder is provided for feeding and guiding a trim material to be ruffled into contact with the stiffener blade. A ruffler blade is coordinately displaceable from a first position wherein the ruffler blade is in contact with the stiffener blade to a ruffle forming position proximate the needle sewing position. The ruffler blade effects a sandwiching of the trim material between the ruffler blade and stiffener blade at the first contact position of the ruffler blade and folds a portion of the trim material between the first contact position of the ruffler blade and the sewing position of the needle under the remaining portion of the trim material between the first contact position and the sewing position of the needle.
