The film sealing and wrapping machine with a rotary cut and seal jaw is provided. The rotary cut and seal jaw has an internal sliding mechanism which provides for smooth and quiet operation. The rotational speed of the jaw may be varied to increase through put and to provide for a title bag around products. The rotary cut and seal jaw may comprise a seal bar and pressure pad may both be spring loaded to self align the seal bar and pressure pad during the sealing and cutting process. Lastly, a gap defined by a belt disposed upstream and downstream of the seal bar and pressure pad may be mechanically linked to the pressure pad through a control carriage.

A riveting system, for use in mechanically linking adjacent workpieces, including a rivet having a height greater than a sum of thicknesses, measured along a line of riveting, of the workpieces being linked, so that the rivet can pass fully through the workpieces. The system also includes a riveting die, which may be a separate product. The die includes a protrusion extending from a peak toward a transition point; and a trough having a trough surface. The trough surface includes a trough inner wall, extending from the transition point to a trough bottom, and a trough outer wall, extending from the trough bottom to a trough outer edge. The technology also includes computerized systems for comparing a load-displacement profile of riveting to a pre-set profile to determine whether the riveting was performed properly.

A method of fastening at least one second object to at least one first object, wherein mechanical vibration acts from a sonotrode on the second object to fasten the second object to the first object. Between the sonotrode and the second object, an auxiliary sheet is placed, for example of paper. After the vibration stops, the auxiliary sheet is displaced relative to the sonotrode for a next fastening step.

A system and process for bonding involves a pocket made into one article is used to secure that article to another using a flowable, curable material (e.g., resin) which during saturation enters through a passageway and at least partially fills the void. When the article is cured, the article is bonded to another article to which resin has also been applied since the void (now containing cured material) is larger than the passageway.

A flexible sealing tube is described that is adapted to be installed in and extend along a bore in the ground for use in a system for exchanging of energy with the ground. The flexible sealing tube has a first tube end to be installed at an inner part of said bore, and the flexible sealing tube is closed in the first tube end. The flexible sealing tube also has a first channel and a second channel extending in a longitudinal direction (L) of the flexible sealing tube, the first and second channels being in fluid connection with each other. The first and second channels are formed by the flexible sealing tube.

There is described a method for forming a tube (3) of a web (4, 4) of packaging material comprising the steps of advancing the web (4) of packaging material along a web advancement path (P), overlapping a first lateral edge (19) of the web (4, 4′) of packaging material with a second lateral edge (20) of the web (4, 4) of packaging material for obtaining a longitudinal seam portion of the tube (3) and fusing at least an internal outer surface (34) of the first lateral edge (19) and an external outer surface (37) of the second lateral edge (20) with one another for longitudinally sealing the seam portion of the tube (3). The step of fusing comprises at least the substeps of directly heating the external outer surface (37) of the second lateral edge (20) and heating by contact the internal outer surface (34) by establishing contact between the internal outer surface (34) and the directly heated external outer surface (37).

A method for producing a frame component for a door frame structure of an aircraft. A connecting zone is generated on a first and a second assembly surface of a connecting component in each case by generating a surface texture on the assembly surfaces, wherein the connecting component is formed from a metal material. The assembly surfaces of the connecting component are placed against a door frame member and against an attachment member, wherein the door frame member and the attachment member are each formed from a fiber-reinforced thermoplastics material. Furthermore, the connecting component and the door frame member are welded, and the connecting component and the attachment member are welded. A frame component and a door frame structure are also described.

An assembly is provided for induction welding. This assembly utilizes a heat shield (e.g., a mica heat shield) with a recess. An induction welding coil may be disposed within this heat shield recess during induction welding operations. The wall thickness of the heat shield within the recess may be reduced to enhance heat transfer to a workpiece during induction welding operations. Members may engage the heat shield on opposite sides of the recess (and that have an increased wall thickness) to support both the heat shield and the workpiece during induction welding operations, during which a biasing force may be exerted on both the heat shield and workpiece.

During a manufacturing method, an induction welder is provided that includes a concentrator and a coil. The concentrator includes a receptacle and a face surface. The receptacle projects vertically into the concentrator from the face surface to an end of the receptacle. The receptacle extends laterally within the concentrator between opposing sides of the receptacle. The receptacle extends longitudinally within the concentrator along a centerline. The coil is seated and extends longitudinally along the centerline within the receptacle. A first thermoplastic body arranged with a second thermoplastic body are provided. The first thermoplastic body is located vertically next to the face surface. The first thermoplastic body is induction welded to the second thermoplastic body. The induction welding includes: generating an electromagnetic field with the coil; and concentrating the electromagnetic field with the concentrator onto a region of the first thermoplastic body.

During a manufacturing method, an induction welder is provided that includes a concentrator and a coil extending through a receptacle in the concentrator. The receptacle projects into the concentrator from a face surface of the concentrator. A first thermoplastic body arranged with a second thermoplastic body are provided. The first thermoplastic body is located next to the face surface. The first thermoplastic body is induction welded to the second thermoplastic body to provide a weld seam between the first thermoplastic body and the second thermoplastic body. The concentrator extends along a portion of the weld seam. The induction welding includes: generating an electromagnetic field with the coil; and concentrating a portion of the electromagnetic field with the concentrator onto a region of the first thermoplastic body.
