Abstract
A seam is set by pressing while the seam allowances are folded to lie flat against the fabric reverse sides while the fabric face sides are facing each other by running the fabric through a seam allowance separator and folder with the seam constrained against lateral displacement. The constraint may comprise the needle, presser foot and feeder of a sewing machine producing the seam.
Claims18
A method for setting a seam joining, along a seam line, two plies of fabric having face sides and reverse sides similarly orientated with respect to the seam, and further having seam allowances, so that when the plies are separated the seam allowances will tend to remain in contact each with the reverse side of its own ply, comprising the steps of:
- a. feeding the plies together along the seam line;
- b. separating and folding back the seam allowances;
- c. setting the fabric during the said separating and folding step;
- and
- d. constraining the seam against lateral displacement during said separating and folding step.
Apparatus for setting a seam joining, along a seam line, two plies of fabric having face sides and reverse sides similarly orientated with respect to the seam and further having seam allowances, so that when the plies are separated the seam allowances will tend to remain in contact each with the reverse side of its own ply, comprising
- a fabric edge folder comprising tongue means adapted to divide adjacent edges of the two plies of fabric fed thereto, guide means adapted to turn said edges so that said edges lie against the outwardly facing reverse sides of the plies, and pressing means adapted to press the thus turned edges together;
- setting means adapted to set the fabric edges in said turned back condition;
- and seam constraining means adapted to locate the seam against lateral displacement in said setting means.
