A composite wingbox structure formed of reinforced thermoplastic. The composite includes carbon fiber reinforcement and a plurality of insulation elements to localize the heat formed during the process of manufacturing the structure. The process of manufacturing the wingbox includes the steps of interleaving a series of insulations elements within a plurality of laminae and consolidating the insulation elements and laminae to form a laminate. The laminate is then aligned with a support structure such that the insulation elements overlie the supports structure. The laminate is then fused to the support structure using a non-contact heating process, such as inductive welding.

In a packaging machine, a work station has an interior, which is surrounded by a wall and which has arranged therein a tool with at least one heating element or actor. The invention is characterized by a bus node assembly that is attached to the outside of the wall facing away from the interior and which comprises a housing cap, a circuit board and an interface connected to the circuit board and used for connection to a communication bus.

A material welder for welding at least two portions of a weldable material together, including: a top bar assembly and a bottom bar assembly, a portion of the top bar assembly directly above a portion of the bottom bar assembly, the top bar assembly including a first and second heating element substantially in the same plane and the bottom bar assembly including a first and second heating element substantially in the same plane, at least one heating device adapted to selectively heat the first heating elements and/or second heating elements, an actuator device adapted to move the top bar assembly towards the bottom bar assembly and/or the bottom bar assembly towards the top bar assembly, such that the first heating element of the top bar assembly aligns with the first heating element of the bottom bar assembly and the second heating element of the top bar assembly aligns with the second heating element of the bottom bar assembly; a contact surface of the top bar assembly and a contact surface of the bottom bar assembly adapted to contact the material during a welding process.

The present disclosure relates to corner profiles and/or corner reinforcement for liners and linings that are suitable for use with tanks and other storage/containment vessels, such as process tanks, immersion tanks, indoor or outdoor containment pits, gravity feed conduits (e.g., concrete trench, canal, or drain, etc.) for transferring or conveying liquid, grain storage tanks or containers (e.g., dielectric or electrically non-conductive liners for grain storage, etc.), etc. The present disclosure also relates to tanks and other storage/containment vessels including liners and linings with corner profiles and/or corner reinforcement. Additionally, the present disclosure relates to methods, systems, and apparatus for providing corner profiles and/or corner reinforcement for liners and linings.

A cup sealing apparatus with a shaft, a heating element, an alignment plate, and a spring biasing the alignment plate into engagement with the alignment cone. The shaft extends has an alignment cone at an end thereof, the alignment cone having a modified cone taper surface centered about a longitudinal axis. The heating element includes a heating surface operable to adhere a seal to a cup presented to the heating surface. The alignment plate is spaced from the opposite axial surface, and has a profile corresponding with the taper surface so that the profile and the taper surface form a non-circular interface between the alignment cone and the alignment plate. With deflection of the spring, the alignment plate and the heating element are free to deviate from a prescribed orientation and out of coaxial alignment to match a cup axis of a cup presented to the heating surface.

A welding station for producing a wrapping has a support wheel and a welding device housed on the support wheel and having a head assembly that has a welding member, a support body, and a rod axially movable between a retracted position and a forward position. The support body is integral with an axial end of the rod. The welding device has an abutment assembly having an abutment member and a base assembly engaged to the support wheel. The welding device is configurable in an open configuration where the head assembly and the abutment assembly are mutually spaced, the rod is axially retracted, and the abutment member allows the wrapping to be loaded onto and removed from the head assembly, and a welding configuration where the head assembly and the abutment assembly are mutually engaged, the rod is axially forward and the abutment is engaged by the welding member.

A heat-sealing apparatus for forming a composite heat seal structure, includes a belt conveying, heating and press bonding portion configured to convey and heat a heat seal material to form a band-shaped peelable seal, and a die roll press bonding portion configured to add a linear peelable seal to the band-shaped peelable seal in a longitudinal direction of the band-shaped peelable seal for forming the composite heat seal structure.

A head for a horizontal flow wrapper packaging machine for forming a bandolier of product packages. The head includes a rotatable first shaft having a plurality of knife elements each including a blade and first and second upper crimping elements. The head also includes a rotatable second shaft having a plurality of anvil elements. A rotation speed of the second shaft is independent of the rotation speed of the first shaft. Each anvil element includes perforation and cutting surfaces and first and second lower crimping elements. A rotation speed of either the first shaft or second shaft is changed to move either a knife element or an anvil element, respectively, between a perforation position and a cutting position. The first upper and first lower crimping elements and the second upper and second lower crimping elements also mate to crimp the packaging material in either the perforating or cutting positions.
