A method of welding a gasket to a spigot portion of a pipe section is described. The method includes supporting the gasket in a recess on the spigot portion of the pipe section. The gasket includes a seating portion and a sealing portion. The sealing portion includes a first shoulder portion and a second shoulder portion. A first bonding portion extends from the first shoulder portion and a second bonding portion extends from the second shoulder portion. The first bonding portion and the second bonding portion are provided to bond the gasket to the spigot portion. The method further includes heating a portion of the gasket and an adjacent surface of the spigot portion and applying a force onto the portion of the gasket following the application of heat to fuse the gasket onto the spigot portion.

Aspects of the present disclosure are directed to a three-dimensional joint and/or formation thereof, such as by 3D-printing the joint. The joint is provided with an interface region having a curable material in a curable state. The joint is positioned with the interface region in contact with a joinable member, and the interface region is cured to form a bond between the joint and the joinable member. Such an approach may, for example, involve forming a mechanical and/or chemical bond with the joint. Further, by utilizing such a joint (e.g., in a 3D-printed form), complex structural components can be formed from a curable material that can be partially cured with structures formed therein, and cured further to create the bond.

A method and an annular integral gasket are provided for forming a sealing connection between a first tubular member and a second tubular member. The integral gasket comprises at least one flexible sealing portion adapted to form a sealing connection between a first tubular member and a second tubular member. The integral gasket further comprises a bonding layer adapted to be fixedly attached to a tubular member by a joining process. The integral gasket also comprises a body region adapted for supporting the flexible sealing portion and the bonding layer.

In order to provide a bonded part capable of reducing deformation caused by injection pressure of bonding resin and preventing an increase in cost, the bonded part includes a first part, a second part, and a third part, wherein the first part includes a wall portion and a hollow portion surrounded by the wall portion, wherein a first shape portion formed of bonding resin is arranged at a position between the second part and the wall portion, wherein a second shape portion formed of the bonding resin is arranged at a position between the wall portion and the third part, and wherein a third shape portion formed of the bonding resin which connects the first shape portion and the second shape portion is arranged on the wall portion.

A method and a device (10) for welding at least two profiled sections (1) for window or door frames or leaves uses a heating unit (4) introduced between the profiled sections (2, 3) to be joined. At least two heating elements (5, 6) of the heating unit melt the profiled section ends (2, 3) at the end surfaces to be joined. In order to chamfer, in particular remove, a profiled section edge layer (20) of the profiled section ends (2, 3) along the layer surfaces (12, 13) thereof, at least one tool, in particular at least one cutting blade (7, 8), is arranged on the heating elements (5, 6) and is moved such that the material (9) to be melted is displaced into the profiled section interior (11) or into the interior (12) of the profiled section chambers (13). A compression device compresses the profiled section ends (2, 3).

A structural member (10) comprising: (i) a first carrier (12A) and a second carrier (12B), each carrier including a plurality of interconnecting ribs (16), each carrier further including one or more projections (28) extending from exterior walls (30) of each carrier; (ii) one or more secondary members (14) secured to one or more surfaces of each carrier; and (iii) an adhesive material (32) disposed on the first carrier (12A), the second carrier (12B), or both, wherein the first carrier (12A) and the second carrier (12B) are bonded to each other via the adhesive material (32).

A compression device compresses the profiled section ends (2, 3).

A nonwoven industrial fabric comprising a first layer secured to a second layer, with each layer comprising a plurality of flow-through apertures and profiling protrusions, wherein: a) at least a portion of the flow-through apertures of the first layer is aligned with at least a portion of the flow-through apertures of the second layer; b) the first layer comprises a plurality of securing protrusions integral to the first layer; c) the second layer comprises a plurality of detents integral to the second layer; and d) the first layer is secured to the second layer by a plurality of locking pairs, each locking pair comprising a securing protrusion lockably engaged with a detent. A method of making the nonwoven industrial fabric is also described.

A reusable plastic container is provided. The container includes a plastic container body having opposing side panels and opposing end panels. The container body also includes top side panel flaps attached to a top portion of each side panel, and bottom side panel flaps attached to a bottom portion of each side panel. The container body has top end panel flaps attached to a top portion of each end panel, and bottom end panel flaps attached to a bottom portion of each end panel. The top and bottom side panel flaps are each defined with respect to the side panels by a fold line. The fold lines including at least one scored portion and at least one welded portion.

A structural member comprising: (i) a first carrier and a second carrier, each carrier including a plurality of interconnecting ribs, each carrier further including one or more projections extending from exterior walls of each carrier; (ii) one or more secondary members secured to one or more surfaces of each carrier; and (iii) an adhesive material disposed on the first carrier, the second carrier, or both, wherein the first carrier and the second carrier are bonded to each other via the adhesive material.
