This single chain stitch sewing device is provided with a sewing mechanism provided on a front end arm of a delivery robot. The sewing mechanism comprises a sewing motor for supplying power to sewing needles and loopers. When the sewing motor is energized, power is transmitted to the sewing needles via a first power transmission mechanism, this causing the sewing needles to move reciprocally. At the same time, power is transmitted to the loopers via a second power transmission mechanism to rotate the loopers. Accordingly, sewing is performed. The loopers are provided at an end of a post bed on the side closer to the sewing needles.

An item may be formed from structures that include holes. Stitching may be used to form a seam that joins the structures. The stitching may be formed from a chain stitch that passes through the holes. The holes may be formed from loops of knit fabric or other holes. Leather layers, polymer layers, fabric layers, and other structures with holes may be joined using the stitching. During fabrication, a layer of material with holes may be placed on an adjustable-shape fixture having a bed of needles. The shape of the bed of nails in the adjustable-shape fixture may then be changed. After the fixture has been used to transform the shape of one or more of the structures, the structures may be placed on needles in an assembly fixture and the stitching between the structures may be formed. The item may be an electronic device cover or other item.

Garment and manufacturing method, describes a one size garment (1) for different sizes of women or men, made of a fabric comprising at least a natural non-elastic fiber material, a first synthetic fiber material and a second elastic synthetic fiber material, these synthetic fibers being covered by polyurethane and polyethylene, having chain stitch seams (3) using 100% polyester thread (4) in which are also stretchy, which join together the different pieces (2) to form the garment; and in that said garment (1) has a distressed look in certain areas of the material. The manufacture thereof comprises making, by hand or machine, using round point needles and a subsequent wash process in two phases, in which an emulsion to protect the elastic fibers is added.
