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 fastening structure comprises a first plate, a second plate, and a sheet member. The first plate has a first passageway with a first diameter. The second plate has a protrusion with a second diameter smaller than the first diameter. The sheet member is disposed on the first plate such that a second passageway of the sheet member communicates with the first passageway of the first plate and the first plate is interposed between the sheet member and the second plate. A portion of the protrusion extends through the first passageway and the second passageway. The first plate is fastened to the second plate by thermal deformation of the portion of the protrusion extending through the first passageway and the second passageway or by overmolding to the portion of the protrusion extending through the first passageway and the second passageway.

A vacuum adiabatic body, a method for fabricating a vacuum adiabatic body, a porous substance package, and a refrigerator including a vacuum adiabatic body and a porous substance package are provided. The vacuum adiabatic body may include a first plate, a second plate, a seal, a support, a heat resistance device, and an exhaust port. The support may include a porous substance and a film made of a resin material, the film configured to accommodate the porous substance therein. Accordingly, it may be possible to provide a vacuum adiabatic body through an inexpensive process.

Liner having an induction heat sealable layer for sealing to a rim of a container, and a pull tab for ease of removal of the liner from the container rim. An insert is disposed between multilayer upper and lower components, has a heat bondable polyolefin layer that is thermally laminated to polyolefin layers of the upper and lower components, forming a pull tab between the integrated polyolefin layers. The resulting composite resists delamination and can be formed in a single thermal lamination step, avoiding the multiple lamination steps, associated high equipment costs, and complex layer constructions of the prior art.

The present disclosure encompasses three-dimensional articles comprising flexible-composite materials and methods of manufacturing said three-dimensional articles. More particularly, the present system relates to methods for manufacturing seamless three-dimensional-shaped articles usable for such finished products as airbags/inflatable structures, bags, shoes, and similar three-dimensional products. A preferred manufacturing process combines composite molding methods with specific precursor materials to form fiber-reinforced continuous shaped articles that are flexible and collapsible.

An apparatus 10) and a method for manufacturing plastic bags (20) from at least two layers of plastic film (30, 40). The apparatus (10) comprises a lower tool plate (300) and an upper tool plate (400); the lower tool plate (300) is driven by a crank (650) on a servomotor (675). The servomotor (675) is connected to a measuring device (680) for measuring the power consumption.

A device for cardboard storage and removal for a bridge in a corrugated cardboard production line includes a bridge over which a conveyor system for conveying the single-sided laminated corrugated cardboard web is arranged. The exit end of the conveyor system for conveying the single-sided laminated corrugated cardboard web is provided with a clamping and cutting unit and a movable cardboard storage carriage unit is provided under the conveyor system for conveying the single-sided laminated corrugated cardboard web, under which conveyor system a conveyor belt system is provided in the bridge, and in the bridge an opening is provided, under which a waste cardboard collecting carriage is provided. The movable cardboard storage carriage unit stores the cardboard by means of cardboard storage rolls, which retain the single-sided laminated corrugated cardboard web flat on the bridge. In the event that a splicing defect is detected, the defective piece is cut out by the clamping and cutting unit and ejected by the conveyor belt system to the waste cardboard collecting carriage through the opening. Hence, it follows that productivity is improved.

A method of adhesively bonding a first substrate on a second substrate in an adhesive bonding zone by an adhesive joint integrating a support mesh, wherein surplus adhesive joint is folded over onto one or the other of the first or second substrates so that the support mesh is present over the entire adhesively bonded zone after curing.

The present disclosure provides a process. In an embodiment, the process includes A. providing a fitment with a base, the base comprising an ethylene/-olefin multi-block copolymer; B. placing the base between two opposing multilayer films, each multilayer film having a respective seal layer comprising an olefin-based polymer; C. flat sealing the base to each multilayer film with opposing heated flat seal bars, the flat sealing forming opposing seal joints at the flattened base ends; and D. point sealing the opposing seal joints with opposing curved seal bars.

The invention relates to a method for producing a test body (30) for mechanically destructively testing a materially bonded joining connection, wherein the method comprises the following steps: providing an areal fiber composite substrate formed from a fiber composite material which has a fiber material and matrix material in which the fiber material is embedded, applying at least one test fabric and an adhesive to a substrate surface of the areal fiber composite substrate, and curing the adhesive, and therefore a materially bonded joining connection is produced between the test fabric and the substrate surface by way of the cured adhesive,
wherein a Dutch-weave fabric and/or a square-mesh fabric is provided as the test fabric.
