A display protector attachment apparatus for a foldable electronic device according to the present disclosure includes: a frame unit including a frame-first end member at one end and a frame-second end member at another end and configured to support and accommodate the foldable electronic device between the frame-first end member and the frame-second end member; and an inclination-forming fixing unit connected to the frame-second end member and configured to align a protector film assembly to be arranged inclinedly with respect to the foldable display unit of the foldable electronic device by varying mounting heights for both ends of the protector film assembly including a display protector that is to be attached to the foldable electronic device.

A system and a method for securing a panel insert to a panel include a main housing, a heater within the main housing, a coupling rod extending from the main housing, and a clamp assembly coupled to the coupling rod. The clamp assembly is configured to clamp the panel insert to the panel. The heater is configured to cure an adhesive applied to the panel insert to bond the panel insert to the panel.

Proposed is lower rollers of a hot air welder, and more particularly, to a lower roller structure of a hot air welder, which includes a first lower roller unit installed on a worktable to be pivoted vertically and a second lower roller unit installed on a main body to be slidably moved in front and rear, such that a welding operation of flat fabric and a welding operation of a cylindrical shape can be performed in a single hot air welder through alternate use of the first and second lower roller units.

A joining method is provided during which a first thermoplastic component joint section and a second thermoplastic component joint section are arranged between first tooling and second tooling. The second thermoplastic component joint section is abutted against the first thermoplastic component joint section at a joint area. The first thermoplastic component joint section is joined to the second thermoplastic component joint section to provide a unitized thermoplastic structure. The joining includes: pressing the first thermoplastic component joint section against the second thermoplastic component joint section at the joint area between the first tooling and the second tooling using a pressure device; and heating the first thermoplastic component joint section and the second thermoplastic component joint section at the joint area using a first heater configured with the first tooling. The unitized thermoplastic structure is cooled at the joint area using a first cooler configured with the first tooling.

A composite assembly with a laminate of fibre plies impregnated with a laminate matrix material is disclosed having pad of fibre plies impregnated with a pad matrix material, and a part with a body with protrusions which extend from the body and penetrate at least some of the fibre plies of the pad. The pad is bonded to the laminate by a stepped lap joint or a scarf joint. The assembly is manufactured by pressing the protrusions into the pad, and after the protrusions have been pressed into the pad, curing a pad matrix material impregnating the pad, and bonding the pad to the laminate.

A prepreg fabrication system provided with an impregnation zone, which includes: (i) a movable support surface for supporting a continuous web material during impregnation; (ii) an endless roller chain carrying a plurality of linking, rotatable idler rollers, a portion of the roller chain facing the movable support surface; and (iii) pressure applicators for pressing at least some of the idler rollers facing the support surface against the support surface to form pressure nips. The movable support surface is configured to move at a first velocity during operation and the roller chain is configured to revolve at a second velocity different from the first velocity so as to establish a relative velocity between the revolving roller chain and the moving support surface, and wherein the relative movements of the support surface and the roller chain create pressure nips that are moving in the same direction as the moving direction of the support surface.

A seal device includes a medium passage that sends a heating medium to a sealing units, the medium passage includes a heating medium passage portion for sending a heating medium to said communication part so as to heat the pressing part, a cooling medium passage portion for sending a cooling medium to the communication part so as to cool the pressing part, and a passage switch unit that switches between a state in which the heating medium passage portion and the communication part are connected, and a state in which the cooling medium passage portion and the communication part are connected.

An automatic welding machine for lap welding the edges of plastic webs, comprising a movable supporting frame, a heating device for partially melting the plastic webs, at least two opposing, counter-rotating pressing rollers and/or advancing rollers, at least one of which being driven, and at least one driving device comprising a drive motor and at least one gearbox for driving the pressing and/or advancing rollers, wherein the pressing rollers and/or advancing rollers are driven by the driving device by way of at least one flexible shaft. Furthermore, the gearbox can be implemented as a worm gear mechanism comprising a worm that is seated directly on a motor shaft of the drive motor and two counter-rotating worm gears driven by the worm.

An automatic welding machine, comprising a supporting frame and a tensioning device for reversibly joining at least two opposing booms to one another and applying a tension force between these, having an open position in which the opposing booms are separated from one another by a gap and a closed position in which the opposing booms are joined to one another and braced with respect to one another. One boom is mounted in a torsion-proof manner on the tensioning device and is pivotable in relation to the other boom and can be moved out of the open position into the closed position by the pivoting of the tensioning device. The tension force is generated by way of a spring-loaded element disposed on the tensioning device, wherein the spring-loaded element, at one end, is rigidly connected to a supporting element of the tensioning device and, at the other end, is pivotably mounted on the supporting frame by way of a double swivel joint, and the spring-loaded element is tensioned by the pivoting of the double swivel joint out of the open position into the closed position, whereby a torque is applied onto the pivotable boom.

A prepreg fabrication system provided with an impregnation zone, which includes: (i) a movable support surface for supporting a continuous web material during impregnation; (ii) an endless roller chain carrying a plurality of linking, rotatable idler rollers, a portion of the roller chain facing the movable support surface; and (iii) pressure applicators for pressing at least some of the idler rollers facing the support surface against the support surface to form pressure nips. The movable support surface is configured to move at a first velocity during operation and the roller chain is configured to revolve at a second velocity different from the first velocity so as to establish a relative velocity between the revolving roller chain and the moving support surface, and wherein the relative movements of the support surface and the roller chain create pressure nips that are moving in the same direction as the moving direction of the support surface.
