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. A folded insert 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.

A machine comprising: a flexible band (1) unwinding unit (11), a flexible band (1) folding unit (14), a drive unit (31) for moving the flexible band (1) in a forward movement direction (DA), a welding unit (16) and a laser beam cutting unit (53) for separating each individual flexible package from the flexible band (1) and for providing a fill opening in each flexible package by at least one fill opening cut, the laser beam cutting unit (53) having associated therewith a separator device, movable in a vertical direction and including an insertable separator element (41), interposed between the opposite faces of the folded flexible band (1), in an area adjacent to the fill opening (3), for separating the opposite faces of the flexible band (1) during cutting operations to prevent the fusion thereof.

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.

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 of sealing a first component to a second component comprising the steps of locating at least one fiber reinforced polyimide resin layer against a first sealing surface on a first component and against a second sealing surface on a second component. At least one fiber reinforced polyimide resin layer is compressed against the first sealing surface and the second sealing surface prior to curing at least one fiber reinforced polyimide resin layer. At least one fiber reinforced polyimide resin layer is heated to promote flow and conformation to the first sealing surface and the second sealing surface. At least one fiber reinforced polyimide resin layer is cured to provide a fluid tight seal between the first component and the second component.

A multi-layer bladder includes: a first bladder layer; a mask including a plurality of apertures; a second bladder layer bonded to the first bladder layer within the apertures in the mask and where the mask is not present between the first and second bladder layers, where the mask is configured to prevent bonding of the second bladder layer to the first bladder layer where the mask is present; and a fluid channel that is located between the first and second bladder layers and that extends to the mask from an outer edge of the multi-layer bladder.

A conduit embedded in thermoplastic and adhered to a pipeline with a porous material assisting in the adhesion. The porous material is adhered to the pipeline, the porous material having at least some pores occupied by the thermoplastic. The porous material may be a sleeve of fibrous material. The adhesion may be accomplished by positioning a sleeve of fibrous material around a guide, bringing the thermoplastic into contact with the sleeve and heating the thermoplastic to cause the thermoplastic to enter pores of the sleeve. The guide forms a barrier preventing the thermoplastic from reaching a portion of the sleeve, and that portion is adhered to the object. This method may also be applied to adhere a thermoplastic, with or without a conduit, to any object.

An attachment part (10) for connecting to a structural part (30). The attachment part (10) has an attachment part longitudinal axis (A), and a weld portion (11) to be welded to the structural part (30) by torsional ultrasonic welding. The weld portion (11) has a contact surface for contact with a torsion sonotrode (70), and a weld surface (13) for connecting to the structural part (30). The weld portion (11) is delimited, at least portionally, by an inner vibration decoupling zone (14). The inner vibration decoupling zone (14), at least portionally, surrounds an inner portion of the attachment part (10).

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.

A system and method for forming a seam between at least first and possibly second pieces of material used to form an inflatable product utilizes at least a first and potentially a second seam forming members that are attached to an inside wall of a piece of product material that comprises the inflatable product proximate each end. The inflatable product is comprised of one or more pieces of product material and one or more seam forming members located at any location where a seam is necessary. A first portion of the seam forming member attaches to a first edge of a first piece of product material and a second portion of the seam forming member attaches proximate a second edge of the first piece of product material. The seal forming can be accomplished by radio frequency, ultrasonic, heat or other types of welding, and adhesive or chemical based bonding.
