A welding process of an inflatable product is provided that includes using isolating members between first and second portions of weldable tensioning members to resist the first and second portions of the weldable tensioning structures being welded together during welding of the first portions to a first sheet of weldable material and welding of the second portions to a second sheet of weldable material.

A method for producing composite profiles comprises providing a first profile part extending in a longitudinal direction, made from a first plastics material, with a profile region produced from a second plastics material thermally plasticizable at a first temperature, providing a second profile part extending in a longitudinal direction, made from a material not thermally plasticizable at the first temperature, and with a receiving structure formed along the longitudinal direction of the second profile part, with which the profile region of the first profile part is connectible, bringing the profile region of the first profile part into contact with the receiving structure of the second profile part, plasticizing the second plastics material of the profile region by heating to the first temperature and deforming the plasticized profile region while forming a positive engagement between the profile region and the receiving structure while maintaining the geometry of the receiving structure.

Aspects of the disclosure relate to manufacturing a balloon envelope for use in a stratospheric balloon system. For instance, a stream of polyethylene mixture us extruded through an extruder in order to orient molecules of polymer chains of polyethylene and to provide an oriented film. The oriented film is passed through an electron beam and thereby crosslinking the polymer chains to provide a cross-linked film. The cross-linked film is heat sealed to form the balloon envelope.

A manufacturing apparatus of a display device includes a first jig configured to hold a first member; a second jig located under the first jig and coupled to or separated from the first jig such that the first member is locatable between the first jig and the second jig; fixing parts located at both ends of the second jig and configured to hold a second member between the first member and the second jig, the second jig including a pad; and a stage located under the pad and provided with a groove formed therethrough and having an area smaller than an area of the pad when viewed in a plan view, wherein one portion of the pad, which faces the stage, is configured to be within the groove.

A system for treating a deep abdominal wound. The system includes a wound dressing. The wound dressing includes a visceral-protective layer, a compressive layer, and a sealing layer. The visceral-protective layer is configured to be positioned in an open abdomen. The compressive layer is configured to be disposed proximate to the visceral-protective layer. The compressive layer includes a pattern of voids configured for anisotropic collapse of the compressive layer when under negative pressure. The sealing layer is configured to form a sealed space in the open abdomen. A negative pressure source configured to provide negative pressure to the compressive layer.

A method and system for fabricating an article using a first bonding module having a first bonding module face and a second bonding module having a second bonding module face include supplying a first non-woven fabric to at least one of the first bonding module face and the second bonding module face, and supplying a plurality of elastic strands to a surface of the first non-woven fabric. The method and system further include entrapping a first elastic strand between a first pair of adjacent bonds in a first row in the first non-woven fabric, entrapping a second elastic strand between a second pair of adjacent bonds in the first row, and creating a third pair of adjacent bonds in the first row free of elastic bands therebetween. The third pair of adjacent bonds is located between the first pair of adjacent bonds and the second pair of adjacent bonds.

Polytetrafluoroethylene (PTFE) composite articles that have a macro textured surface. The composite articles include at least two different PTFE membranes in a layered or stacked configuration. The composite article has a macro textured surface characterized by a plurality of strands raised from the surface of the PTFE membrane. The strands may be formed of either interconnected nodes of PTFE or of at least one nodal mass of PTFE and have a length equal to or greater than about 1.5 mm. The macro textured surface provides a topography to the first PTFE membrane. The composite articles have a bubble point from about 3.0 psi to about 200 psi, a thickness from about 0.01 to about 3.0 mm, and a bulk density from about 0.01 g/cm.sup.3 to about 1.0 g/cm.sup.3.
