A method for connecting at least two structural parts of an orthopedic component, wherein the structural parts are retained in an orienting device while oriented in relation to each other, and an intermediate space thus being formed between the structural parts. The orienting device and the structural parts together form a cavity, which has a flow connection to at least one feed connection, via which an adhesive for adhesively bonding the structural parts is introduced into the cavity.

During a formation method, a first component and a second component are provided. The first component is configured from or otherwise includes a first fiber-reinforced thermoplastic composite. The first component also includes a base and a material buildup on a portion of the base. The second component is configured from or otherwise includes a second fiber-reinforced thermoplastic composite. The second component is arranged with the first component. The second component abuts the material buildup. The second component is vibration welded to the first component to provide a weld joint between the first component and the second component. At least a portion of the material buildup is displaced during the vibration welding.

A laminate tube with an invisible longitudinal overlapped side seam formed from overlap welding an edge of one margin of a laminate sheet comprising an outer plastic layer (A), a barrier layer (B), and an inner plastic layer (C) of the same material type as the outer plastic layer (A) to the other edge of the opposite margin of the laminate sheet, such that an inner surface of the laminate tube has a hump in a overlapped region, while an outer surface of the laminate tube is smooth without a hump in the overlapped region; and a process for manufacturing the laminate tube by a laminate tube manufacturing machine. The laminate permits fracture-proof welding of longitudinal margins of said laminate to give a continuous tube which is suitable for manufacturing of high-quality plastic tubes, high-quality plastic bags and the like.

A method for watertight welding, and components formed using that welding method, wherein the welding method includes providing a first component half with a groove and a protruding ridge located therein, providing a second component half with a tenon shaped to match the profile of the groove, disposing the tenon inside the groove such that the tenon contacts the protruding ridge, applying an ultrasonic power source near the groove to melt the protruding ridge, and applying opposing vertical force to the first component half relative to the second component half, such that the protruding ridge wedges in a bonding seam between an outside surface of the tenon and an inside surface of the groove.

The present invention relates to a method for producing a container which consists of a thermoplastic at least to some extent and comprises at least a first compartment element and at least a second compartment element joined to the first compartment element in a joining region by thermoplastic welding. The invention also relates to a plastic container which can be, and preferably is, produced according to said method.

A catheter drainage member (112) configured to be attached to a catheter tube (116), the drainage member comprising: body (115) having an inner surface (114); a well (120) defined by the inner surface of the body, the well configured to receive the catheter tube and an adhesive (122); and wherein the well is configured to selectively distribute the adhesive between the inner surface and the tube.

A method of manufacturing a wind turbine blade is described, the blade being formed from at least a pair of blade shells being joined together. For at least a portion of the wind turbine blade, the blade shells are joined by an overlamination applied between the edges of the blade shells, thereby substantially reducing or eliminating the need for a structural adhesive to join the blade shells, particularly in the area of the leading edge of the blade or the root region of the blade trailing edge. The overlamination can be formed from the same material as the blade shells themselves, thereby minimising the possibility of structural faults or cracks due to differences in materials or stiffness levels at the interface between the blade shells.

A process for continuous welding of a sheet of plastic material for manufacturing flexible packages, comprising a step of positioning the sheet relative to the welding device, putting ends of the sheet into contact, forming a weld by heating, pressing and cooling the ends of the sheet that are in contact, acquiring a primary temporal signal with a sensor, the primary temporal signal proportional to a thickness of the weld, transforming the primary temporal signal into a primary frequency signal and defining a low-frequency spectrum, a medium-frequency spectrum, and a high-frequency spectrum from the primary frequency signal, reconstructing a secondary low-frequency signal from the low-frequency spectrum, and determining the thickness of the weld based on the secondary low-frequency signal.

The invention relates to a tube head (1, 2) intended to form a packaging, the head (3, 6) being intended to be welded to a tubular skirt (8, 9) in order to form the said packaging, and the tube head (1 2) being thermoformed from a sheet (20, 21). The invention also relates to a method for manufacturing such a tube head (1, 2) and a tube with said head (3, 6).
