A mold, a molding apparatus, and a method for manufacturing articles or components is used to manufacture an article or component of the article that at least partially comprises an ultraviolet (UV) curable material. The mold and apparatus comprise at least one mold wall formed of a cyclic olefin copolymer, which is in contact with UV radiation curable material and allows the article or component of the article to be exposed to UV radiation for a period of time in order to provide for at least partial cure thereof.
METHOD OF MANUFACTURING HYBRID ADDITIVE FABRIC, THE FABRIC, AND TOOLS FOR MANUFACTURING FABRIC
The present invention relates to a method of manufacturing a fabric, and the fabric made by the method. Fabric made from yarn or filament is currently produced by either a knitting process which involves the interloping of yarn, or a weaving process which involves the interlacing of yarn, or the entanglement of fibre on the surface of yarn. These construction methods have a definite look, texture and functionality. The invention seeks to provide an alternative fabric construction especially for yarn, filament, thread and fine wires or such like. A method of manufacturing a fabric by laying a parallel surface of yarn, such as spun yarn, wire, thread or such like, then a second layer of parallel array of filament at an 90-degree angle dispensed from a 3D printer or 3D printer pen. Yarn and filament can be layered in a variety of designs and not limited to a parallel array of yarn to accommodate unlimited design shapes and structures. The method can be repeated to create a fabric surface built by multiple layers upon layer. Alternating one layer of yarn or such like and one layer of 3D printed filament. Each layer offers space to embed components such as semi-conductors. Semi-conductors that are an essential component of electronic devices, enabling advances in communications, computing, healthcare, military systems, transportation, clean energy, and countless other applications. In addition, Drug delivery scaffolds that allow for controlled spatiotemporal releases to active compounds can also be accommodated within the layer of spun yarn and 3D filament. The spun yarn or filament can be embedded with conductive yarns or E-yarns to enhance functionality further. The surface of the spun yarn may be brushed to raise the surface fibres, to increase the entanglement and enhance the blending of spun yarn and the fluid filament dispensed via a 3D printer or 3D pen. The combination of 3D printing and spun yarn or such like provides an additive manufactured hybrid textile. Therefore, the present invention offers numerous advantages over woven, knitted or parallel layered fibre on yarn entangled fabric surfaces.
Process for Manufacturing a Conveyor Belt
Methods of manufacturing a conveyor belt (126) include applying a rubber composition (114) to a first side of fabric reinforcement (112) and scattering productive thermoplastic elastomer pellets (106) onto a second side of the fabric reinforcement to produce an uncured belt structure (120). The uncured belt structure (120) is continuous fed into a double belt press (116) to press the productive thermoplastic elastomer pellets (106) together with the fabric reinforcement (112) to produce an uncured belt (128). Uncured belt (128) is then heated in the double belt press (116) to a temperature of at least 300 F. and maintained in the double belt press (116) under a pressure of at least 12 psi and a temperature of at least 300 C. for a residence time of at least 20 minutes to produce a cured conveyor belt (130), which is continuously withdrawn from the double belt press (116).
Method for manufacturing absorbent article
A method for manufacturing an absorbent article, the method including: while a lower bandlike member is transported in a transport direction, a process in which a cutting position is determined and an adhesion area is formed on each side of the cutting position of the lower bandlike member in the transport direction; a process in which leg elastic members are placed so that a part of each of the leg elastic members overlaps the adhesion area, the leg elastic members being stretched in a direction having a component parallel to the transport direction; a process in which an upper bandlike member is stacked on and adheres to the lower bandlike member and the leg elastic member on the adhesion area; a process in which the lower bandlike member and the upper bandlike member are folded on the center in the intersecting direction; a process in which a welded section on which the lower bandlike member and the upper bandlike member are to be welded to each other is formed on each side of the cutting position in the transport direction; a process in which and the lower bandlike member, the upper bandlike member and the leg elastic members are cut together on the cutting position, a lower exterior member and an upper exterior member which are shaped in the form of underpants are cut and separated, the leg elastic members which are stretched contract towards the adhesion area from positions at which the leg elastic members are cut, the contraction being performed while the leg elastic members shifting relative to the lower exterior member and the upper exterior member.

SEAT FOR VEHICLES
A seat for vehicles including a seat cushion, a seat back, and a head rest has the following arrangement to ensure that a surface member can be relatively easily but positively removed from a urethane pad if a foam molding defect is found in the urethane pad in integral molding of the urethane pad and the surface member. In the seat for vehicles, any one of the seat cushion, seat back, and head rest has a configuration where a surface of the urethane pad is covered with the surface member. The urethane pad and the surface member are partially bonded together by integral molding.
