A method and device for connecting and repairing a shear web includes the method steps of dry-fitting a shear web insert in a rotor blade assembly to establish a perimeter gap at an angled perimeter interface between the shear web insert and the rotor blade assembly, the angled perimeter interface positioned between the shear web insert and at least one adjacent surface of a first shear web, a second shear web, a first side of the rotor blade assembly, and a second side of the rotor blade assembly, and then injecting a bonding paste into the perimeter gap. The rotor blade assembly can include a connecting device having at least one pre-fabricated clip.

A connection method and a connectable system to enable the connection of three components with simpler means. To this end, the components are positioned in such a way that connection surfaces of the first and second component and engaging elements of the first or second component and the third component face each other; and the first component is bonded to the second component by means of the connection surfaces, and the first or second component is positively connected to the third component by means of the engaging elements during the movement of the components in relation to each other along the common joining axis, the third component being fixed parallel and transversely to the joining axis after the connection by means of the first and the second component.

The present invention relates to a method for manufacturing a flexible skin which has at least one insert adhered thereto. In a first step, the skin is molded on a mold surface. In order to adhere the insert to the skin, an opening is first made in the skin giving access to the back face of the insert. The insert is positioned with its back face against the front face of the skin and an adhering layer is provided which is adhesively connected to the back face of the skin layer which surrounds the opening in the skin layer and, through this opening, to the back face of the insert. The adhering layer is preferably produced by applying a layer of a hardenable material, in particular a curable polyurethane composition. Since the back face of the insert engages the front side of the skin penetration of hardenable material to the front face of the insert is avoided.

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.

Butt welding machine (2) adjusting the ends of plastic pipes and welding them to each other, which comprises a cutter (1) having a driving element (16) for moving the trimmer (13) by being driven, at least one movable claw (24, 32, 33) moving depending on a connector to hold pipes which are positioned, a motor (21) which does not have direct connection with the cutter (1) and transfers power to the cutter (1) and to the movable claw (24, 32, 33) via one connector for each, a drive gear unit (22) which provides driving energy from one point to the cutter (1) and the movable claw (24, 32, 33) which wherein the cutter (1) and the movable claw (24, 32, 33) needs to be had two different driving motions performed via two different connectors, a drive gear unit (22) providing driving energy to the movable claw (24, 32, 33) from one point.

Methods for joining a first blade component and a second blade component of a rotor blade together includes printing and depositing, via a computer numeric control (CNC) device, at least one three-dimensional (3-D) grid structure at a first joint area of the rotor blade. The first joint area contains the first blade component interfacing with the second blade component. The method also includes providing an adhesive at the first joint area to at least partially fill the grid structure. Further, the method includes securing the first blade component and the second blade component together at the first joint area via the adhesive.

A film pasting tool is used to paste one surface of a film on a member-to-be-pasted at a predetermined position. The tool comprises a flexible tabular body, a first adhesive part, a front surface thereof being adhesive, provided on one surface of the body, and a second adhesive part, a front surface thereof being adhesive, provided on a part of a region other than a region where the first adhesive part is provided out of one surface of the body. An other surface of the film is pastable on the front surface of the second adhesive part, and when the other surface of the film is pasted on the front surface of the second adhesive part, the front surface of the first adhesive part is exposed in such a manner that the front surface of the first adhesive part is pastable on the member-to-be-pasted.

A method and apparatus are presented. The apparatus comprises a first unitary structure, a second unitary structure, and a number of joints between the first unitary structure and the second unitary structure. The first unitary structure has a plurality of T-shaped cross-sections. The second unitary structure has a plurality of T-shaped cross-sections.
