A bonder and a method for bonding corrugated sidewalls to a thermoplastic belt at a splice joint. Two heating jaw assemblies with complementary and confronting corrugated vertical faces clamp a thermoplastic belt to a base of the bonder with a corrugated sidewall section separated from the belt across a splice joint received in a corrugated slot formed between the confronting vertical faces. Corrugated bonding strips at the bottoms of the corrugated vertical faces apply heat to melt the bottom of the sidewall section on opposite sides to bond the corrugated sidewall section to the base.

A container of a fluid including a collar having a passage and a pair of laminated film sheets heat-welded along perimetral welding lines so as to form a bag, the pair of sheets also being heat-welded to the collar so that the passage in the collar provides access to interior of the bag; the outer surface of the collar, in a zone in which the collar is welded to the pair of sheets has, seen in section, an oblong shape with two tapered ends aligned along at least one axis along which the pair of sheets are welded.

A glue filling method for a multilayer thin film sensor structure is disclosed herein. Two outer layers of a composite heat-resistant membrane are carved to have desired patterned holes; an inner layer is interposed between two outer layers to form a layered structure. The composite heat-resistant membrane is stuck onto the multilayer thin film sensor structure with the patterned holes aligned to an electric-conduction through-hole of the multilayer thin film sensor structure to form a filling region. A conductive glue is filled into the filling region. Sustained by the inner-layer heat-resistant membrane, the conductive glue protrudes from the patterned hole to cover a portion of the conductive metals on the surface of the multilayer thin film sensor structure. Thereby are simultaneously achieved a water-proof effect, an airtight effect and a fine interface compatibility.

The present invention relates to a method of manufacturing a plurality of wind turbine blades. The method comprises first, second and third stationary moulds (64a, 64b, 64c), moulding respective first upper and lower shell halves (74a, 76a), removing and turning the first upper shell half (74a), and positioning and bonding it on the first lower shell half (76a) to form a closed wind turbine blade shell. This is repeated for continuously manufacturing a plurality of wind turbine blades.

An aerosol container suitable for use as an aerosol dispenser. The aerosol container includes at least a valve and product delivery device joined to an outer container. The valve and product delivery device have respective annular welds or other seals joining the valve and product delivery to the outer container. The welds, or other seals may be concentric, with one circumscribing the other, in the same plane or different planes. Suitable product delivery devices include bags and dip tubes.

Disclosed is a molded container having multiple storage spaces, which includes: a molded body having at least two storage spaces and a connection groove to connect the adjacent spaces to each other; a valve unit seated and fixed in the connection groove to allow the adjacent spaces to communicate with each other or to prevent communication therebetween; and a cover member fixed on the molded body to cover and finish the valve unit coupled to the storage spaces and the connection groove. The valve body of the valve unit is coupled on top of the molded body, thereby enabling easy and quick assembly of a final product and enhancing productivity.

The invention relates to a method for assembling a first and a second part of a lighting device for a vehicle by mirror welding, including a step of supplying the parts wherein each part comprises, in the interface area thereof for contact with the other part, a weld bead intended to come into contact against the weld bead of the other part during the mirror welding, the weld bead of at least one of the parts is provided with a plurality of expander ribs (N) spread out along the weld bead, in such a way as to locally expand the width of the weld bead.

A joining element has an anchoring portion for in-depth anchoring in the object and a head portion arranged proximally of the anchoring portion with respect to an insertion axis. The head portion has a lateral outer surface that has a structure that is well-defined, especially within tight tolerances. The joining element is positioned relative to an object of a non-liquefiable material such that the anchoring portion reaches into an opening of the object or is placed adjacent a mouth thereof. Then, the joining element is pressed towards a distal direction, to press the anchoring portion into the opening, while mechanical vibration energy is coupled into the joining element by a tool, in an amount and for a time sufficient for liquefaction of a portion of the thermoplastic material to cause interpenetration of the thermoplastic material into structures of the object.

The invention relates to a sonotrode for an ultrasound welding system for welding workpieces (20, 30), comprising a pressure element (2) which has a contact surface, which pressure element can be applied to carry out the welding process with said contact surface on one of the workpieces (20) to be welded to each other, wherein the contact surface has an annular design. A centering pin axially projecting over the contact surface is arranged inside the annular contact surface. The invention also relates to a method for welding a connection element (20), in particular an adapter for a PDC sensor, to a component (30), in particular an exterior add-on part of a motor vehicle.

A first object is anchored in a second object. The first object has a material with thermoplastic properties, and the second material has a material that is solid and is penetrable by the first material when in a liquefied state. The second object has an insertion face with an opening having a mouth in the insertion face, and the first object has an insert portion that for anchoring is placed in the opening or about the mouth thereof. For anchoring, energy suitable for liquefaction of the first material impinges in an amount and for a time sufficient for at least partial liquefaction of the first material and interpenetration of the first and second materials. The second object, around the opening, has an anisotropic strength with respect to forces perpendicular to the opening axis.
