Abstract
The present invention is generally directed to a method of making a lined fabric product having an open hem construction. An open hem construction refers to a lined fabric product in which a liner fabric is hemmed separately from a cover fabric. In this configuration, the liner fabric is allowed to drape independently from the cover fabric. In the past, fabric articles, such as curtains and draperies, having an open hem construction were primarily made exclusively by hand. The process of the present invention, on the other hand, allows some automation, improving the speed and cost at which the products are made.
Claims21
A method of making a lined fabric product in which, at one end of said product, a liner fabric is hemmed separately from a cover fabric, said method comprising the following steps:
- providing a cover fabric and a superimposed liner fabric, each of said cover fabric and said liner fabric including corresponding top edges, bottom edges and a pair of opposing side edges, said cover fabric being attached to said liner fabric along each of said opposing side edges to form a first vertical hem and a second vertical hem;
- detaching a portion of said first vertical hem and a portion of said second vertical hem adjacent said bottom edges of said liner fabric and said cover fabric;
- forming a hem along said bottom edge of said liner fabric and a separate hem along said bottom edge of said cover fabric;
- and
- reattaching said detached portions of said first vertical hem and said second vertical hem.
A method of making a lined fabric product in which, at one end of said product, a liner fabric is hemmed separately from a cover fabric, said method comprising the following steps:
- providing a cover fabric and a liner fabric, said liner fabric being superimposed on said cover fabric, said fabrics each including a top edge, a pair of opposing side edges, and a bottom edge;
- attaching said cover fabric to said liner fabric along each of said opposing side edges to form a first vertical hem and a second vertical hem, said side edges being attached together by a column of stitches;
- unraveling a portion of said first vertical hem and said second vertical hem adjacent to said bottom edges of said liner fabric and said cover fabric;
- forming a hem along said bottom edge of said liner fabric and a separate hem along said bottom edge of said cover fabric;
- and
- reattaching said unraveled portions of said first vertical hem and said second vertical hem.
A method of making a lined fabric product in which, at one end of said product, a liner fabric is hemmed separately from a cover fabric, said method comprising the following steps:
- feeding a cover fabric and a liner fabric simultaneously into a folding and sewing device, said device folding over and sewing together corresponding side edges of said cover fabric and said liner fabric, said device forming a first vertical hem and a second vertical hem along said side edges, each of said hems including a stitch line where said cover fabric and said liner fabric have been sewn together;
- unraveling a portion of said stitch line of said first vertical hem and a portion of said stitch line of said second vertical hem adjacent to a bottom edge of said cover fabric and said liner fabric;
- forming a hem along said bottom edge of said liner fabric and a separate hem along said bottom edge of said cover fabric;
- and
- restitching said unraveled portions of said stitch lines of said first vertical hem and said second vertical hem.
A lined fabric product comprising:
- a face fabric having a first vertical hem located along a first vertical edge and a second vertical hem located along a second and opposite vertical edge, said hems being created by folding said vertical edges at least once thereby creating vertical fold lines at said respective edges;
- said sewn product further comprising a liner fabric, said liner fabric being superimposed on said face fabric and being sewn to said face fabric at least at said vertical hems, said liner fabric having a width that is narrower than the width of said face fabric, said width being about the distance between the innermost and opposite fold lines for decreasing the thickness of said vertical hems.
