Apparatus and methods of cleaning a sealing head (23) of a capsule filling line, comprising operating an ablation unit (10) to irradiate the sealing head (23) to ablate a residue off the sealing head (23).

The present invention is provided with: an insulation holder formed of a thermoplastic resin material and having a first opening; a wire connection ring formed of a thermoplastic resin material and having a second opening; and a joining component inserted astride in the first opening and the second opening, the joining component being formed of a metal material having a higher melting point than those of the thermoplastic resin materials, the joining component having a higher stiffness than those of the insulation holder and the wire connection ring, wherein a welded part is formed by welding in at least a part of an area where each of the insulation holder and the wire connection ring has contact with the joining component.

There is provided container sealing apparatuses and methods for sealing openings of containers with film. The apparatuses comprise: a pressing member configured to press a film into contact with a container; and a sealing beam source configured to emit one or more sealing beams, each of said sealing beams being incident on the container and/or the film, each of said sealing beams being incident local to a respective part of the pressing member which engages the container so as to join the film to the container; the container sealing apparatus being configured to move the container relative to the pressing member, such that a region of the container which is engaged by the pressing member changes.

The present disclosure relates to a recyclable, padded paper mailer that is water resistant, heat sealable, and provides padded protection. The mailers in accordance with this disclosure find utility as padded mailing envelopes such as e-commerce mailers, bubble packaging pillows, or any other protective shipping packaging.

A process for producing a polymeric stiffened sheet-like component, for example a panel, for aircraft construction. Production includes integration of hollow stiffening profiles, for example closed omega stringers, onto a sheet-like component, for example an external skin, where the stringers and external skin are produced from thermoplastic composite material. The stringers are integrated onto the external skin by establishing contact between the stringers and the external skin and melting thermoplastic composite material with exposure to heat and pressure at the areas of contact between external skin and stringers. Melting of the other sections of the stringers is avoided with a pressurized cooling fluid with a temperature significantly below the melting point of thermoplastic composite material, the fluid flowing through the airtight enclosed space in the stringers. Use of closed airtight thermoplastic omega stringers allows integration of the stringers onto the external skin in absence of any flexible tube within the stringers.

Disclosed is a method of resistance welding between composite articles. A conductive element is provided between faying surfaces, having a plurality of lower resistivity electrode portions spaced apart along the length of the contact area between the composite articles. The electrode portions can be used to spot weld across the electrode portions, and along a longitudinal portion of the conductive element between the electrode portions by application of an electrical current. Also disclosed are apparatus for use in the resistance welding methods and composite articles and structures and elements incorporating the conductive element.

A blister pack includes a housing having a plurality of cavities and a cover sealed to the housing and enclosing the cavities. The cover includes a base layer, at least one security element, and a heat protection layer. The heat protection layer includes one of an amorphous polymer and a semi-crystalline polymer.

The invention relates to a method for checking, prior to welding, two components made of polymer material, the method comprising a step of determining respective values relating to the roughness of the components, a step of determining respective values relating to the cleanliness of the components, a step of determining respective values relating to the temperature of the components and automated means for halting progression to a subsequent method step should the predetermined conditions not be met.

The invention relates to a device (1) for measuring the surface condition of a component (4, 5, 6). Said device (1) comprises a measurement member (2) comprising at least one sensor (21, 22, 23) capable of measuring at least one datum relating to the surface condition of the component (4, 5, 6) and at least one transmitter (24) capable of transmitting the datum from the sensor (21, 22, 23). The measurement device (1) also comprises a support (3) for the measurement member (2), the support comprising means for connecting same to the component (4, 5, 6).
