Filed:

Nov 26, 1975

Appl. No.:

5/635568

Inventors:

Richard Russell - Tappan NY

Assignee:

U.S. Blind Stitch Machine Corporation - Plainview NY

International Classification:

D05B 3508

US Classification:

112135

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.

Abstract:

A stitch shortening and tacking assembly for use in a sewing machine is provided. The shortening and tacking assembly is particularly suited for use with a sewing machine wherein a fabric is advanced between a presser foot and a platen disposed in a first feeding position by a reciprocating feeder that is synchronized with respect to a rib and sewing needle. The sewing needle is synchronized with respect to the feeder and rib to stitch the fabric after the web has been advanced by the feeder. The platen is adapted to be displaced from the feed position to a stitch shortening position whereby the web is advanced through a shorter interval between sewing operations to thereby shorten the length of each stitch effected thereby. The platen is further adapted to be displaced from the stitch shortening position to a stitch tacking position whereby a portion of the platen is biased against the presser foot to thereby prevent the fabric from being advanced between sewing operations.
