A barn curtain having a transparent panel and a non-transparent panel is prepared by a welding machine. The welding machine has an inner heater assembly including a first roller wheel, an inner plate assembly having a lower inner plate and an upper inner plate spaced apart from the lower inner plate in a vertical direction, and a heater, and a first roller assembly including a second roller wheel aligned with the first roller wheel. A side of a transparent panel is fed through the lower inner plate and a side of a non-transparent panel is fed through the upper inner plate. The plates are heated with the heater to partially melt the side of the transparent panel and the side of the non-transparent panel. The side of the transparent panel and the side of the non-transparent panel are pressed between the roller wheels and joined.

A method of manufacturing an armour layer of a flexible pipe for transporting fluid from a subsea location and apparatus are provided. The method comprises winding a first length of composite tape to form a first section of the armour layer and positioning an end region of the first length of composite tape over an end region of a second length of composite tape to form an overlapping tape section. Heat and pressure is applied to the overlapping tape section to form a joined overlapping tape section in which the first length of tape is joined to the second length of tape such that the joined overlapping tape section has a lap shear strength of at least 11 MPa. The joined overlapping tape section and the second length of composite tape are wound to form a second section of the armour layer.

The joiner for preparing the barn curtain further comprising a transparent panel feeder feeding transparent panel material to the welding machine. The joiner for preparing the barn curtain further comprising a support roller supporting the feeding of the non-transparent panel feeder and the transparent panel feeder. The joiner for preparing the barn curtain further comprising a barn curtain spooler receiving the barn curtain output from the welding machine.

In certain examples, a machine that forms a web into bags or pouches includes a sealing section through which the web is conveyed in a machine direction. The sealing section is configured to form a lap seal in the web and has an input end configured to receive the web which has a first web section and a second web section. An ultrasonic sealer with a horn and an anvil defines a nip therebetween through which the first web section passes. The ultrasonic sealer is configured to form the lap seal in the first web section. The anvil is positioned between the first web section and the second web section. An output end is configured to dispense the web with the lap seal formed therein.

A manufacturing method and an apparatus enable high productivity. A method for manufacturing an oxidized fiber bundle includes joining an upstream precursor fiber bundle and a downstream precursor fiber bundle together with a joining fiber bundle, and oxidizing the joined precursor fiber bundles by feeding the joined precursor fiber bundles through an oxidization furnace. The joining includes applying an oiling agent to a joint area of a joining target precursor fiber bundle before joining the joining target precursor fiber bundle and the joining fiber bundle together. A quantity of the oiling agent adhering to the joint area is 0.15 to 0.85 wt %.

Disclosed is a welding machine for synthetic resins. The welding machine for synthetic resins performs welding of fabrics using ultrasonic waves and through preheating sufficient not to burn off a coating solution on the surfaces of the fabrics using hot air so as to achieve rapid and firm welding due to concentrated molecular decomposition and melting on the bonding surface between the fabrics, allows both an ultrasonic horn and a welding wheel to be rotated vertically so as to achieve rapid and stable entry of the fabrics and welding of the fabrics while preventing the fabrics from slipping, and achieves stable welding of various fabrics through adjustment of pressing force of the welding wheel depending on the thickness or the material of the fabrics, etc.

A method of constructing an inflatable fluidic actuator that includes generating a tube configuration with one or more shapes of fluid-impermeable membrane material, the tube configuration having a first tube end and a second tube end and an internal tube face and an external tube face. The method also includes coupling a first and second interface to the tube configuration at the first and second tube ends by respectively coupling each interface to the tube configuration at a respective tube end by generating at least one of: a first circumferential bond between the fluid-impermeable membrane material and one or more sidewalls of the interface; and an external face bond between fluid-impermeable membrane material at the tube end onto an external face of the interface.
