A process of constructing an air tight and water tight seam, comprising cutting a sheet of selected material into two or more panels, sealing the panels at respective selected edges using an ultrasonic machine to form a seam, overlaying the seam with a tape made of the same selected material, and sealing the tape and seam using a radio frequency (RF) welding machine.

Water-soluble films, water-soluble unit dose articles, and related methods of making and using the same.

A method of bonding a first object to a second object, including the steps of: providing a profile body having a first profile body portion; providing the first object, wherein the first object has thermoplastic material; providing the second object, wherein the profile body is separate from and attachable to the second object or wherein the second object includes the profile body; embedding the profile body in the first object such that the first profile body portion is within the thermoplastic material of the first object. Embedding the profile body in the first object is caused by mechanical energy impinging on the first object and/or on the second object while the first object and the second object are pressed against each other.

A tape layup apparatus whereby the tape layup performance on a surface to be laid up can be enhanced is provided, the tape layup apparatus being an ATL apparatus 10 having an ATL head 20 for laying up with pressing a tape 1 on a laid-up surface 2a, the ATL head 20 equipped with a pressing part 30 to press the tape 1 on the laid-up surface 2a and a parallel linkage 40 to operate in a manner that allows a pressing position and/or a pressing attitude of the pressing part 30 to follow a form of the laid-up surface 2a.

A manufacturing apparatus of a metal-composite patch part and a manufacturing method thereof include: a laser oscillator oscillating a laser; a first laser irradiator used to perform pattern processing on one surface of a metal with a laser by receiving the laser from the laser oscillator; and a metal-composite bonding apparatus for bonding a composite tape to the one surface of the pattern-processed metal. The apparatus includes a feeder roller supplying a composite tape to the one surface of the pattern processed metal and a pressing roller pressing the composite tape to the one surface of the metal. The bonding performance between the metal and the composite and productivity may be improved because the number of the processes related to the metal-composite patch part manufacturing process may be significantly reduced.

A device for joining a lens with a housing of a lighting device of a motor vehicle, having a receiver for receiving and securing the housing and a pre-centering device for positioning the lens on the housing, wherein the pre-centering device includes a frame element and a plurality of positioning elements that are attached to the frame element for receiving the lens, wherein during a pre-centering process, the frame element of the pre-centering device is movable together with the joined lens relative to the receiver in such a way that the lens is aligned on the housing, which is received in the receiver.

An insulating device including an outer shell, an inner liner forming a storage compartment, an insulating layer positioned in between the outer shell and the inner liner, wherein the insulating layer provides insulation for the storage compartment, and an opening configured to allow access to the storage compartment.

A system and method for welding thermoplastic components by positioning and moving a heated plate between the components to melt their respective faying surfaces, and as the plate moves, pressing the components together so that the melted faying surfaces bond together as they cool and re-solidify, thereby creating a composite structure. The plate has a heated portion which is positioned between and heated to melt a portion of the first and second faying surfaces. A manipulator mechanism moves the plate along an interface from between the portion to between a series of subsequent portions of the first and second faying surfaces, thereby welding the thermoplastic components along the entire interface to create the composite structure. An injection device may also move behind the plate and reciprocally inject a polymer between the first and second faying surfaces to provide toughness and crack arresting properties.

Provided is a composite material bonding apparatus that can reduce a cycle time when composite material members are bonded to each other. The composite material bonding apparatus includes a sheet-heater moving device that places a graphite heater at an insertion position between a first bonded surface of a first composite material member and a second bonded surface of a second composite material member such that the graphite heater is parallel to the first bonded surface and the second bonded surface facing the first bonded surface, and retracts the graphite heater to a retraction position from the insertion position. The first bonded surface and the second bonded surface are heated at the insertion position by the graphite heater, and then the graphite heater is moved to the retraction position by the sheet-heater moving device.

A method of joining a non-metallic pipe to a metallic pipe. The pipe may be wrapped with one or more sheets of reinforcement material (e.g., pre-impregnated fiberglass, carbon fiber, or aramid fiber) and then fitted with an adapter or fitting that is connectable to a metallic pipe. The reinforcement material may be heated using a heating apparatus which allows the material to bond to the pipe to strengthen the joint.
