Bonded polymeric film laminates comprising core polymer film layers individually coated on at least one side with a heat fusible polymer layer and fusion bonded together by the application of heat and pressure at a temperature at which each heat fusible polymer coating bonds together adjacent core polymer film layers, where the melting point or softening temperature of the heat fusible polymer is at least 3 C. below that of the core layer polymer, and the lamination temperature is at or above the melting point or softening temperature of the heat fusible coating polymer, where the heat fusible polymer coating layers are thinner than the core polymer film layers, where the coated core polymer film layers are uniaxially stretched by 2 to 40, and the stretched coated core polymer film layers are cross-plied. Methods for forming the laminates, coated films from which the laminates are formed, and articles formed from the laminates are also disclosed.

A vessel for storing pressurized gas. The storage vessel may be manufactured in a variety of predetermined shapes. Plural frame members are interconnected with each other, collectively forming a lattice frame. A network of internal supports is disposed within the interior of the lattice frame, the internal supports being made of a carbon-reinforced composite material. The storage vessel has an outer shell made up of layers of carbon-reinforced composite material sheets enveloping the exterior of the lattice frame.

High-frequency hot-pressing continuous automatic production lines for dimensional bamboo timbers, and production methods thereof are provided. The production line can include a clip-up store and feeding mechanism fixed with one end of a three-roller type gluing system. An other end of the three-roller type gluing system is fixed with one end of a system for loading, layer up and stacking non-glued bamboo sheets. The outer side edge of the system for loading, layer up and stacking non-glued bamboo sheets is connected to a front inner end of a plate stack conveying system. A high-frequency press and high-frequency generator system is located at a rear inner end of the system for loading, layer up and stacking non-glued bamboo sheets.

Apparatus and method for applying discrete components of a first substrate to a second substrate includes a programmable servo motor having a shaft. The servo motor is programmed to rotate the shaft in a first phase and a second phase at a variable angular velocity in a single direction. The apparatus also includes a crank member connected with the shaft, a connector link connected with the crank member, and a tamper member connected with the connector link. When the shaft rotates in the first phase, the tamper member travels from a first position to a second position to displace a selected portion of the second substrate into contact with the discrete component.

A device for joining multi-layered panels made of individual boards has a height-adjustable workbench. layers of boards arranged at an angle to each other and joined together. A guide for the material is provided at least on one side of the workbench, preferably on two adjoining sides. The device comprises at least one transport device for transporting boards to the processing position.

A method allows for rapid manufacture of relatively thick adhesive coatings using a continuous process, where a single thin coating is continuously converted into a single thicker adhesive laminate. An exemplary process includes the steps of: (1) producing a web having a first surface with an adhesive layer and a second surface with a release liner; (2) slitting the web longitudinally into a first section and a second section; (3) laminating a backing film to the adhesive layer of the first section; (4) removing the release liner of the laminate of step (3) exposing the adhesive layer of the first section; and (5) laminating the second section to the laminate of step (4), wherein the adhesive layer of the laminate of step (4) is combined with the adhesive layer of the second section.

A system for laminating an optical film according to an exemplary embodiment of the present disclosure includes a panel transfer unit to transfer a panel, a first laminating unit installed on a transfer line of the panel to laminate an optical film on a first surface of the panel along a first direction parallel to a transfer direction of the panel, and a second laminating unit installed on the transfer line of the panel to laminate an optical film full-cut into a predetermined length on a second surface of the panel along a direction perpendicular to the first direction.

A helmet shell is formed having an outer section of fibrous layers, a middle section of fibrous layers and an inner section of fibrous layers. The outer section layers contain high tenacity abrasive fibers in a resin matrix. The middle section layers contain high strength polyolefin fibers and are in the form of woven or knitted fabrics with a resin matrix. The inner section layers contain high strength polyolefin fibers and are in the form of non-woven fabrics with a resin matrix. The helmet is lightweight and resists penetration of rifle bullets.

The present specification relates to a display unit manufacturing method and an optical film laminating system.

A method of manufacturing curved composite structural elements can include fabricating a web ply in a flat curve over a removable substrate and laying up the ply on a curved web surface of a manufacturing tool. The method also can include laying up a diagonal ply with fibers oriented at +/45 from the centerline of the web surface. The method further can include cutting a unidirectional composite tape into segments and laying up the tape segments to form a cross ply with a fiber orientation normal to the centerline of the web surface. One or both edges of the diagonal and cross plies may be folded over one or two sides of the manufacturing tool to form one or two flange surfaces. Additionally, a cap ply can be laid up on one or both flange surfaces using composite tape. The structural element layup can then be inspected and any excess composite material can be trimmed away.
