A thermoplastic pipe and a method for producing it are described. The thermoplastic pipe includes a hollow inner liner layer, a semi-consolidated core comprising commingled fibers, and a shrink wrap outer layer. The commingled fibers comprise at least one thermoplastic fiber and at least one reinforcing fiber. The semi-consolidated core layer comprises a thermoplastic polymer matrix that is organized along the at least one reinforcing fiber. The method includes winding commingled fibers over the hollow inner liner layer at a designated angle to produce a core layer, covering the core layer in a heat shrinkable wrap, and heating to produce a semi-consolidated core layer. The semi-consolidated core layer comprises a thermoplastic polymer matrix that is organized along the at least one reinforcing fiber.

Articles, for example multi-ply fibrous structure-containing articles such as multi-ply sanitary tissue products, containing two or more fibrous structure plies, and more particularly to multi-ply articles containing two or more fibrous structure plies having a plurality of fibrous elements wherein the articles exhibit improved bulk and absorbent properties compared to known articles and methods for making same, are provided.

Methods, apparatuses, devices, and substrates are described. Multiple layers of a substrate may be bonded using a laser beam that is rotating about an axis and while the substrate is laterally translated with respect to the laser beam. Further, a direction of the laser beam may be modified such that the laser beam is incident on a surface of a layer of the substrate at an acute angle with respect to the surface. In such cases, the respective layers of the substrate may be bonded by irradiating the surface with the rotating laser beam, thereby resulting in spiral-shaped bonding lines between the layers. The layers may be bonded when one of the layers is coupled with an element (e.g., a blocking element), and the acute angle of the laser beam may enable irradiation an area that is below the element while leaving the element unaffected by the laser beam.

A method for manufacturing a sandwich panel as a semi-finished product where at least one layer of a non-metallic material is positioned between at least two metallic layers. At least one of the metal layers is shaped into a three dimensional layer and the metal layers are material closured to each other by a tack weld on the metallic contacts between the metallic layers to enable resistance weldability of the semi-finished product in order to connect the semi-finished product to a desired combination of solutions.

A method for ultrasonically bonding elastic laminates is provided. The method includes attaching a removable shell layer to at least a portion of an exterior surface of a rotating roll, advancing at least a laminate material assembly along a machine direction to dispose the laminate material assembly on the removable shell layer, applying a vacuum pressure to the laminate material assembly, ultrasonically bonding the laminate material assembly, and advancing the elastic laminate including the laminate pattern along the machine direction.

A vacuum insulation panel manufacturing method that makes it possible to manufacture low-cost, high-performance vacuum insulation panels, and a vacuum insulation panel are provided. This method of manufacturing a vacuum insulation panel (1) involves: a stacking step in which a first metal plate (20) is overlaid on one side of a thermally insulating core material (10), and in which a backing member (50) having an opening (51) and a second metal plate (30) having an exhaust port (32) are placed, with the opening (51) and the exhaust port (32) overlapping, overlaid on each other on the other surface of the core member (10) in the order of backing member (50) and second metal plate (30) from the core member (10) side; a first welding step for welding outwards of where the core member (10) is disposed in the first metal plate (20) and the second metal plate (30); a vacuum creating step for evacuating air from the exhaust pert (32) to create a vacuum in an inner area which is held between the first metal plate (20) and the second metal plate (30) and in which the core member (10) is arranged; and a laser welding step in which, in a state in which the inner area is made into a vacuum by the vacuum creating step, the exhaust port (32) is sealed by means of a sealing material (60) and the sealing material (60), the second metal plate (30) and the backing member (50) are laser welded.

The present disclosure is directed to an apparatus including a first laminating component configured to laminate a dry film onto a substrate using heat, and a focused cure module configured to selectively cure a first portion of the dry film without curing a second portion of the dry film. The first portion forms a perimeter that surrounds the second portion.

A multi-layered laminate is described along with methods of making and/or using the same. The laminate may be thermally or ultrasonically laminated and have a bond pattern including a plurality of bond points having an area of about 0.5 mm.sup.2 to about 2.5 mm.sup.2 (e.g., about 1 or 1.6 mm.sup.2) and at least a portion of the bond points in the plurality are separated from each other (in the horizontal and/or vertical direction) by 6 mm to about 25 mm. The laminate may be useful in medical applications.

The present invention relates to a surface-modifying layer including a polymeric component having a hydroxyl group and an unsaturated hydrocarbon group, in which a molar ratio of the unsaturated hydrocarbon group to the hydroxyl group is 0.01 or more and less than 1, a surface-modifying sheet including the surface-modifying layer and a release sheet, a laminate, a surface-modified member and a coated article, in which the surface-modifying sheet is used, a method for producing a surface-modified member, and a method for producing a coated article.
