A method of making a folded micro-wire substrate structure includes providing a flexible substrate and first, second, and third portions. One or more electrical conductors are formed on or in the flexible substrate. The flexible substrate is folded with a first fold between the first and second portions so that the first portion is located adjacent to the second portion in a perpendicular direction. The flexible substrate is folded with at least a second fold between the second and third portions so that the second side is between the second portion and the third portion in the perpendicular direction. The folded flexible substrate is secured to form the folded micro-wire substrate structure.

The present invention provides a production method for an underpants-type disposable diaper in space-saving and simple facilities while reducing the risk of occurrence of wrinkles, including: supplying a continuous sheet material in the continuous direction thereof; disposing resilient and elastic members for imparting elasticity to a ventral side outer body and a dorsal side outer body at a CD direction intermediate portion of the sheet material; folding CD direction one side and other side parts across the CD direction intermediate portion toward the side of the CD direction intermediate portion with the resilient and elastic members, sandwiching and fixing the resilient and elastic members in the folded sheet material, and joining together the folded parts and the CD direction intermediate portion to form a continuous elastic belt; cutting the elastic belt at a CD direction intermediate position to obtain a dorsal side elastic belt and a ventral side elastic belt, and then assembling an inner body to the dorsal side elastic belt and the ventral side elastic belt.

A method for manufacturing an absorbent article including a topsheet, a backsheet, a core, a discrete barrier member, a first cuff, and a second cuff. A barrier substrate may be cut into a discrete barrier member including a leading edge portion, an opposing trailing edge portion, and a central portion therebetween. The discrete barrier substrate may be transferred onto a folding roll. A first cuff substrate and a second cuff substrate may be advanced onto the folding roll such that the discrete barrier substrate may be disposed on at least a portion of the first cuff substrate and the second cuff substrate. The discrete barrier member may include a fold between the leading edge portion and the trailing edge portion. A topsheet substrate may associate with at least a portion of the discrete barrier member, the first cuff substrate, and the second cuff substrate.

A fabric containing carbon fibers impregnated with a silicone, polyurethane or acrylic emulsion which is then dried together with the fabric is disclosed. A protective layer containing a film, a woven or non-woven fabric is applied onto one side of the fabric.

An elongate flattened thermoplastic tube has an inflation edge and an opposite edge. The tube includes spaced transverse seals that define sides of pouches. The tube includes lines of weakness that allow adjacent dunnage units to be separated. A frangible line of connection is disposed in one two superposed layers of the tube proximate to the inflation edge. This frangible connection may be broken to permit inflation of the inflatable pouches.
