A carrier for seam formation and sealing comprising a roller assembly having at least one roller; a housing for holding the roller assembly; a fastening member for mounting the roller to the housing; and the fastening member is an interchangeable mechanism.

A joined body includes: a thin plate including through holes; first members each including: a base portion and a protruding portion inserted into one of the through holes; and a second member placed oppositely to the base portion via the thin plate and made of a material that is of a same kind as a material of the first members. The thin plate is made of a material having a specific gravity smaller than the materials of the first and the second members. The second member and an end portion of the protruding portion are connected together by melt-solidification. A post-joining hardness difference in a range of 30% along a direction orthogonal to a joint interface between the second member and the protruding portion, the range being centered on the joint interface, is equal to or less than 90% of a pre-joining hardness difference.

A joint structure comprises a first panel and a second panel joined together by mechanical clinching. The joint structure includes a join region that is formed so as to extend in an elongated shape by forming plural clinched portions in a given arrangement by mechanical clinching. At least one clinched portion of the plural clinched portions is clinched from an opposite panel side from other clinched portions of the plurality of clinched portions.

To reduce concern of separation due to a user's unintended application of a load.

A joined body of a first structure member having a frame-like structure and a second structure member joined to an inside of the first structure member, wherein the first structure member has a protruding portion in which an anchor shape is formed, the second structure member has a hole portion that comes into contact with the protruding portion of the first structure member, and the protruding portion has a stress concentration portion on which stress concentrates when a load is applied to the second structure member.

A panel assembly including a main panel, a first side panel, a second side panel, a first tab, a second tab, and an extension. The first tab defines a planar notch into which the extension is positioned to restrict movement of the first side panel and the second side panel.

A profile assembly produced from a first profile and a second profile connected longitudinally by cold joining. Both profiles bear complementary clamping structures on long sides thereof facing toward one another for cold joining together. The clamping structure of the first profile comprises a clamping head formed on a web and forming an undercut on each side of the web by way of a greater extension in the profile transverse direction in relation to that of the web. The clamping structure of the second profile comprises a clamping head receptacle for accommodating a section of the clamping head and a clinching leg, formed on a profile-exterior leg of the clamping head receptacle, having a first profile arm protruding before cold joining and a second profile arm formed at an angle thereon, the free end of which engages behind the clamping head and, before cold joining, faces toward a clamping pocket of the first profile. The clamping head receptacle is tapered with respect to its open width and/or the clamping head is tapered with respect to its material thickness of the section to be inserted into the clamping head receptacle, wherein the section of the clamping head pressed into the clamping head receptacle is connected to the clamping head receptacle in a metallically sealed manner.

A local connection of contact surfaces of top and bottom sheets is formed in a defined connection zone. The zone is polygonal and the top and bottom sheets jointly form within the periphery of this zone a connecting lip with their first side faces located opposite one another cut obliquely through their sheet thickness. These first side faces of the sheets and their adjacent obliquely-oriented second side faces in the zone are complementarily beveled in the form of a conical wall running downwards and inwards, so that in the vicinity of these second neighboring side faces the underside of the bottom sheet protrudes inwards past the top surface of the connecting lip at the location of the top outside edges of its first side faces. A method and an apparatus are arranged to implement the local connection.

In the present invention, a through-hole (2) and a compression periphery part (3a) at which the core of the resin foam (1c) is compressed are provided in a fastening part of a resin-foam core composite plate (1). A cylindrical part (11a) of a metallic fastening member (11) is inserted into the through-hole (2) from the proximal end side of a wall part (4). The fastening member (11) is crimped to the distal end of the wall part (4) via an eyelet member (12) placed on the outside of the wall part (4) so as to forcibly spread the cylindrical part (11a). The fastening member (11) and a counterpart member (A) are fastened together by tightening a nut (14) onto a bolt (13) inserted into the cylindrical part (11a).

Provided is a junction. In one aspect, the junction includes a first member, the first member formed of a first material, and a second member overlapping with the first member, the second member formed of a second material, the first and second members defining an overlapping space. In accordance with this aspect, the junction additionally includes an expanded metal joint located in at least a portion of the overlapping space, the expanded metal joint comprising a metal that has expanded in response to hydrolysis.

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.
