Connection method for chassis sealing elements

A method for connecting the joint of two ends of at least one chassis sealing element. In order to allow a secure and quick connection of the ends and allow an additional unhindered passage of air and moisture between hollow chambers within the chassis sealing element via the joint when using a profiled hollow chamber, the ends are first arranged at a distance to each other, and a shapeless bonding agent is applied to at least one end. The bonding agent is then heated, and the ends are brought into mutual contact, whereby the ends are bonded at the joint by way of the heated bonding agent.

11697251 · 2023-07-11 · ·

A joining method and assembly for an aircraft. To improve the characteristics or permit hitherto impossible connections between thermoplastic and thermoset components, a multi-material joining method is disclosed in which a thermoplastic connecting region is formed on the thermoplastic component. The connecting region is connected to the thermoset component by interdiffusion. For this purpose, the uncured second component is brought into contact with the connecting region and heat is supplied. An interdiffusion layer is formed which fixedly connects the second component and the connecting region to one another and thus joins the first component to the second component.

Edge attached film-foam sheet

The present disclosure generally relates to devices and methods for furniture protection. More particularly, the present disclosure relates to foam-film sheets configured to protect furniture from damage. An exemplary foam-film sheet as disclosed herein includes a sheet of foam material having a first lateral edge and a second lateral edge; a sheet of film material having a first lateral edge and a second lateral edge; a first seal between a portion of the foam material proximate its first lateral edge and a portion of the film material proximate its first lateral edge; and a second seal between a portion of the foam material proximate its second lateral edge and a portion of the film material proximate its second lateral edge, wherein the film and foam are substantially unsealed along the entire transverse width between the first and second sealed portions near the lateral edges of the foam material.

Adhesive application apparatus

There is provided an adhesive application apparatus capable of efficiently applying an adhesive without inhibiting curing of the adhesive. An adhesive application apparatus of the present invention includes a mounting table 10, an adhesive dosing unit 20, and an ultraviolet irradiation unit 30, and it applies a delayed-ultraviolet-curable adhesive 200 to a surface of a panel 100. The panel 100 is mounted on a mounting surface S10 of the mounting table 10. The adhesive dosing unit 20 applies the adhesive 200 to the surface of the panel 100 mounted on the mounting table 10 by discharging the adhesive 200 from an adhesive dosing port H20. The ultraviolet irradiation unit 30 irradiates the adhesive 200 dosed from the adhesive dosing port H20 with ultraviolet light L. Here, the ultraviolet irradiation unit 30 irradiates the adhesive 200 with the ultraviolet light L along the mounting surface S10 before the adhesive 200 dosed from the adhesive dosing port H20 is applied to the surface of the panel 100.
