A method and tooling for manufacturing flexible articles of manufacture such as garments, bags, backpacks and accessories that require hemmed edges. The method and tooling are compatible for use in an automated system and simplify the hemming process by performing the hemming operation on a flat pattern of material before the pattern of material has been joined with other patterns of material to form a finished or intermediate three-dimensional workpiece. This facilitates the formation of the hem by allowing the hem to be formed on a flat material pattern on a flat surface, thereby facilitating the folding, creasing and affixing of the hem without the requirement of human dexterity and labor.

An encased wire for a garment includes a wire with first and second ends and a casing surrounding the wire. The casing includes a first fabric ribbon woven from a polyamide that resists penetration by at least one of the ends of the wire. The casing has a first edge, a second edge, and a first, stitched seam disposed adjacent to the first edge to close the casing, thereby containing the wire. The casing may be a single layer construction or a multi-layer construction. Selected regions of the casing resist penetration by the wire. Other selected regions provide increased comfort to the wearer. A sewing machine and a method of manufacture of the casing also are provided.

A method for seaming cloths of protective clothing includes the steps of: preparing plural cloths for forming protective clothing; having the cloths to form two connecting areas, and then adhering the two connecting areas to form a joint band; utilizing a first auxiliary fixture to fold the joint band to form a folded joint band; utilizing a second auxiliary fixture to fold two lateral sides of a water-resistant cloth into two folded edge areas, and having the two folded edge areas to be adhered respectively onto the folded joint band, such that the water-resistant cloth wraps the folded joint band; and, applying a sewing machine needle to have a water-repellent thread to penetrate repeatedly the two folded edge areas and the folded joint band along a sewing path, so that the water-resistant cloth is fixed to the folded joint band. In addition, another method for seaming cloths is provided.

Various examples are provided related to transporting and sewing material in, e.g., automation of sewing robots. Multiple pieces of layered materials can be transported on a flat planar surface while maintaining the material layer's position and orientation relative to one another during a sewing procedure of these materials along any arbitrary seam shape. In one example, among others, a system includes a sewing machine including a sewing needle, a material holding assembly and a translation system. The material holding assembly can include mechanical fingers that can contact material on a sewing plane adjacent to the sewing needle and a structural grounding system supporting the mechanical fingers. The translation system can reposition the material on the sewing plane via the mechanical fingers. Clearance around the sewing needle can be provided by repositioning individual mechanical fingers around the sewing needle.
