Laser Part Retention System and Method

A system for laser processing includes a plate assembly having a first plate, a second plate secured to the first plate, and a pressure chamber located between the plates, a connector extending into and in fluid communication with the pressure chamber, and a fixture having a first end attached to the second plate of the plate assembly, a second end having surface having at least one opening and shaped to fit a part to be retained and laser processed, and a conduit extending therethrough in fluid communication with the pressure chamber and the at least one opening. During use, a pressure generated by a pump may be communicated to the conduit of the fixture through the pressure chamber to provide pressure (e.g., a suction effect) at the opening(s) to secure the part in place, e.g., with respect to another part, so they can be laser processed.

Sealing supported by pressurized air

A method of closing a packaging tray comprises arranging a packaging tray between a lower tool and an upper tool of a sealing station, positioning a cover film above the packaging tray between the lower tool and the upper tool, and pressing together the cover film and the packaging tray by a lower sealing surface of the lower tool and an upper sealing surface of the upper tool cooperating with the lower sealing surface. During the pressing together, a connection is established between the cover film and the packaging tray along a sealing seam. While the cover film and the packaging tray are being pressed together, an overpressure is locally generated by supplying pressurized gas from a pressurized-gas source, the overpressure cooperating as a counterpressure with the lower sealing surface or with the upper sealing surface so as to press the cover film and the packaging tray together.

METHOD FOR MAKING A GAS-TIGHT CONTAINER IN ELASTOMERIC MATERIAL

A method for making a gas-tight container (1) in elastomeric material comprises: providing two or more separate elastomeric portions (2, 3), cleaning and/or roughening the gluing surfaces (6) of the gluing edges (5), applying an adhesive (7) onto the previously cleaned, degreased and/or roughened gluing surfaces (6), assembling the portions (2, 3) to form the container (1) and inserting between the gluing surfaces (6) a raw elastomeric tape (8) not yet cured, applying a cold pressure on the overlapped gluing edges (5), heating the overlapped gluing edges (5) to thermally activate the curing of the raw tape (8), cooling the gluing areas.

METHODS FOR JOINING A FIRST THERMOPLASTIC SUBSTRATE WITH A SECOND THERMOPLASTIC SUBSTRATE

A method for joining a first thermoplastic substrate and a second thermoplastic substrate, each including a polyaryletherketone material having a first melting temperature. The method includes co-consolidating a first semicrystalline thermoplastic film with the first thermoplastic substrate to yield a first co-consolidated structure. The first semicrystalline thermoplastic film defines a first bonding surface of the first co-consolidated structure and includes a polyaryletherketone material having a second melting temperature that is less than the first melting temperature. The method further includes co-consolidating a second semicrystalline thermoplastic film with the second thermoplastic substrate to yield a second co-consolidated structure. The second semicrystalline thermoplastic film defines a second bonding surface of the second co-consolidated structure and includes a polyaryletherketone material having a third melting temperature that is less than the first melting temperature. The method further includes fusing the first bonding surface to the second bonding surface. The method yields a stacked structure.

SEALING SUPPORTED BY PRESSURIZED AIR

A method of closing a packaging tray comprises arranging a packaging tray between a lower tool and an upper tool of a sealing station, positioning a cover film above the packaging tray between the lower tool and the upper tool, and pressing together the cover film and the packaging tray by a lower sealing surface of the lower tool and an upper sealing surface of the upper tool cooperating with the lower sealing surface. During the pressing together, a connection is established between the cover film and the packaging tray along a sealing seam. While the cover film and the packaging tray are being pressed together, an overpressure is locally generated by supplying pressurized gas from a pressurized-gas source, the overpressure cooperating as a counterpressure with the lower sealing surface or with the upper sealing surface so as to press the cover film and the packaging tray together.

20210380297 · 2021-12-09 ·

A system for manufacturing tamper evident packaging, for example a bag with a tamper evident seal, includes a noncontact sealing device, a manufacturing conveyor, and in some implementations, a tensioning device and a closure device. The manufacturing conveyor conveys the bag to opposing pairs of in-feed belts of the non-contact sealing device, wherein the belts hold opposing sides of the bag together and a laser with an outlet positioned between a first pair of the belts spot welds the bag along a specified line to fuse the opposing sides of the bag together proximate an opening of the bag. In implementations including the tensioning device and the closure device, the tensioning device draws the opposing sides of the bag together prior to the bag entering the noncontact sealing device, and the closure device applies a removably coupleable closure to the bag after the bag exits the non-contact sealing device.

Process for thermo-adhesive bonding of semi-finished products

A process for thermo-adhesive bonding of semi-finished products includes preparing an inner sock, an outer sock and an impermeable membrane provided with a thermo-adhesive disposed on an inner surface and/or an outer surface of the membrane; fitting the inner sock onto a rigid reference shape; fitting the membrane over the inner sock; fitting the outer sock over the membrane; heating the outer sock, the membrane and the inner sock arranged on the rigid reference shape in an oven until at least partial melting of the thermo-adhesive; cooling the outer sock, the membrane and the inner sock arranged on the rigid reference shape until cross-linking of the thermo-adhesive and stable bonding of the membrane to the outer sock and/or the inner sock. Also, exerting a substantially uniform pressure on the outer sock, the membrane and the inner sock disposed on the rigid reference shape during cooling, so as to compact them.

Flexible pipe and coupling therefor

Construction of a sealed connection between an elastomeric or synthetic polymer flexible pipe or hose and a metallic coupling member. The coupling member surrounds an armor layer at a free end of the flexible pipe or hose. A sealing area is defined by a recessed portion of the pipe coupling into which a sealing material is introduced. An inner liner layer of the flexible pipe or hose may extend into the sealing area where it is bonded to the sealing material. The sealing material and the inner liner layer may each be comprised of a semi-crystalline thermoplastic material. Furthermore, a reinforcement material may be provided in the inner liner layer.

An automobile interior trim has a resin core material and a skin material that is joined on a surface of the resin core material. The automobile interior trim has stitches that are formed on the skin material by sewing the skin material with threads. The skin material and the stitches are cut by a laser beam to generate a cut section. The vicinity of the cut section has a structure in which threads of the stitches and the raw material of the skin material are melted by heat of the laser beam, mixed together, and solidified.
