A device for manufacturing a pleated curtain includes elongate pleating means for forming a first fold in the curtain by folding the curtain around a long side of the pleating means along a fold line, clamping means for clamping a pleat portion of the curtain on either side of the first fold along a clamping line parallel to the fold line such that the pleat portion forms a loop, and control means for controlling the pleating means and the clamping means. The control means move the pleating means and/or clamping means such that the pleating means are arranged from a position inside the loop to a position adjacent the loop, while the clamping means clamp the pleat portion, such that a remaining portion of the curtain is folded round an outer end of the clamping means and a second fold is formed adjacently of and parallel to the first fold.

A fitted sheet (800) includes a first side margin (106) and the second side margin (107) folded about a first fold line (104) and a second fold line (105), respectively, toward a central panel (108) such that sides of the first side margin and the second side margin are separated by a separation (208). A first edge (209) and a second edge (211) occur where the first side margin and the central panel abut, while a third edge (210) and a fourth edge (212) occur where the second side margin and the central panel abut. The first edge includes a first seam (405), while the second edge includes a second seam (406). The third edge includes a third seam (407), while the fourth edge includes a fourth seam (408). Each seam is applied by a different sewing operation. At least two seams are different in color.

A decorative engineered self-hem and a method to prepare the decorative engineered self-hem in a single fabric is disclosed herein. It is prepared without having any additional cut and sew, with various weave patterns designed in a design area 10-20 inches from a selvedge area and the rest of the fabric is woven in conventional weave pattern such as satin/twill. The method of preparation includes cutting the fabric parallel to a selvedge area; folding the fabric overlapping the selvedge area; and folding the full fabric horizontally and, at the same time, hemming of edge of the selvedge area to finish.

A creasing apparatus includes a top plate having an upper surface supporting a fabric, a robot manipulator, a folding assembly mounted on the robot manipulator and configured to make a crease on the fabric by pinching the fabric from above, and a control device configured to control the robot manipulator and the folding assembly.

A sewing system can include a sewing machine; a vacuum pump; and a polymer bag configured to hold a fiber preform and to connect to the vacuum pump so that gas inside the polymer bag is removable by the vacuum pump to thereby reduce a pressure inside the polymer bag to less than an ambient pressure of an outside of the polymer bag, and to compress the fiber preform to a compressed thickness thereby forming a compressed fiber preform, so that a pattern of stitches of a filament are stitchable through the polymer bag and the compressed fiber preform by the sewing machine while the pressure inside the polymer bag is less than the ambient pressure.

A sewing system includes: a robot manipulator; a plurality of assemblies attached to and detached from the robot manipulator and each configured to perform predetermined work on cloth; a server stores process data indicating a relationship between a plurality of processes for manufacturing a sewn product from the cloth and the assembly used in each of the plurality of processes; and a control device configured to select an assembly to be mounted to the robot manipulator based on the process data.
