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.

An article of manufacture comprises a strip that extends along and is centered on a virtual curvilinear path, comprising an arc, having an arc length and a radius. A ratio of the strip-width to the radius is greater than or equal to 0.003. The arc length is equal to or greater than a product of the radius and /64. Within each of discrete strip-regions of the strip, one of the unidirectional reinforcement fibers that is closest to the first longitudinal strip-edge is more buckled than another one of the unidirectional reinforcement fibers that is closest to the second longitudinal strip-edge. Ones of the unidirectional reinforcement fibers that are buckled are parallel to a smallest one of virtual surfaces, joining the first longitudinal strip-edge and the second longitudinal strip-edge.

A packaging container for holding contents such as fresh food. The container comprises a tray having a flange, a pre-formed scaling ring and a flexible film for sealing in the contents of the tray. The sealing ring is made from fiber, filament or tape (FFT) that is shaped into a shape that matches the shape of the tray flange. The sealing ring is adhered to the tray flange by heat welding or other means and the flexible film is adhered to the sealing ring.

Methods for ultrasonic welding of thermoplastic polymer workpieces and assemblies made therefrom are provided. The method may comprise disposing a first region of a first thermoplastic polymer workpiece and a second region of a second thermoplastic polymer workpiece between an ultrasonic horn and an anvil of an ultrasonic welding device. The first workpiece has a preformed deformation and at least one of the first and/or second workpieces has an adhesive precursor applied thereto. The ultrasonic horn or anvil seats within the preformed deformation. Ultrasonic energy is applied from the ultrasonic horn to create a weld nugget between the first and second workpieces. The assembly thus formed has a green strength sufficient to be further processed immediately. The methods provide a robust weld joint with controlled adhesive bondline thickness.

A deflection member that includes a reinforcing member and a plurality of tiles fastened to the reinforcing member.

A narrow waveguide homogenizes laser light traveling from a laser light source of a laser bank through a plurality of laser delivery bundles that include at least a fiber optic bundle leg to weld a plurality of work pieces along a weld line that is narrower than the width of the fiber optic bundle leg. The narrow waveguide has a portion associated with each fiber optic bundle leg that is narrower than the fiber optic bundle leg with which that portion of the waveguide is associated. A reflective bounce plane diverts laser light of the fiber optic bundle leg that does not travel through the narrow waveguide.

A profile body of a not liquefiable material is used as a connecting element between a first object and a second object. The profile body may especially be metallic and/or may be bendable. The profile body, in contrast to a conventional wire, however, has a shape defining a first and a second undercut. The method includes embedding the profile body in the second object so that the second undercut is within material of the second object, and embedding the profile body within material of the first object so that the first undercut is within the first object, and wherein at least embedding of 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.

The invention relates to a device for a vacuum cleaner filter bag comprising a holding device with a passage opening and a closure device for closing the passage opening of the holding device, wherein the closure device comprises a closure flap and an elastic element made of a cross-linked silicone elastomer, and the elastic element is pretensioned in a state in which the closure flap closes the passage opening of the holding device.

Multifunction end effector apparatus and methods for assembling thermoplastic composite articles are disclosed. An example apparatus for assembling a thermoplastic composite article includes a robot and an end effector coupled to the robot. The end effector includes a cutting head, a vacuum head, and a welding head.

A method may comprise applying a first adhesive to a cavity of a bond panel, the cavity defined by a raised body portion of the bond panel, inserting an acoustic insert assembly in the cavity, the acoustic insert assembly being secured in the cavity by the first adhesive, and securing edges of the acoustic insert assembly to the raised body portion of the bond panel with a second adhesive to create a seamless interface between the edges and the raised body portion.
