Apparatus and method for making inflated articles

A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.

Human tissue isolation pouch for use with pouch sealer
10752393 · 2020-08-25 ·

A human tissue isolation pouch for use with a sealer machine to indirectly seal human tissue medical pouches while avoiding cross contamination is herein disclosed. The human tissue isolation pouch comprises a rigid frame supporting a high temperature material and having one or more magnets for removably attaching the human tissue isolation pouch to a sealer machine. During use a medical pouch, which may contain a human tissue sample, is inserted within the human tissue isolation pouch. The jaws of the sealer machine clamp down directly on the high temperature material, thus indirectly heating and sealing the medical pouch inside the human tissue isolation pouch. The sealing machine jaws do not physically contact the medical pouch at any time during the sealing process, and in this way contamination of the sealer machine (and cross contamination of medical pouches from distinct donor cases) is avoided. The rigid frame of the human tissue isolation pouch may be sterilized after each donor event. And the containment bag formed of a high temperature material may be disposed of after each donor event.

INTERMEDIATE TRANSFER MEMBER
20200171813 · 2020-06-04 ·

A heat-curable tape, a kit, and a method for connecting ends of an elongate belt to form an intermediate transfer members suitable for use with indirect printing systems. The kit includes an elongate belt and the heat-curable tape. The kit can include a crimping pin. The method includes using the heat curable tape to join ends of the elongate belt at a seam. A heater is used, in a printing system, for heat-curing the heat-curable tape onto the free ends of the elongate belt so as to form the intermediate transfer member.

AN INDUCTION SEALING DEVICE

An induction sealing device for heat sealing packaging material for producing sealed packages of pourable food products, said sealing device comprising: an inductor configured to induce a current in the packaging material, the inductor comprising conductor elements; a polymer insert holding said conductor elements; and a supporting body holding said polymer insert; wherein the polymer insert comprises a polymer matrix into which boron nitride particles are dispersed.

Bulk Factor Compensated Tool for Fabrication of a Composite Part
20200130291 · 2020-04-30 ·

An example apparatus for fabrication of a co-cured composite assembly includes a layup tool body with a cavity, a thermal expansion insert inserted into the cavity of the layup tool body and a first uncured composite part of the composite assembly is positioned onto the thermal expansion insert, and a solid internal mandrel configured for insertion onto the first uncured composite part. During curing, the first uncured composite part compacts and reduces in thickness while the solid internal mandrel and the thermal expansion insert each increase in size to apply pressure to the first uncured composite part.

Low mass staking module
10625474 · 2020-04-21 · ·

A low mass staking module includes a punch having a cavity on a first side, a contact surface on the second side opposite the first side, and a circular flange extending about an outer edge thereof, the punch formed of a thermally-conductive material, an annular housing engaged with the punch about the circular flange at a first end, and a heating element located inside the annular housing. The heating element has an output side in contact with the contact surface of the punch, the contact surface having a shape conforming to a shape of the output side of the heating element. The punch is desirably a low thermal mass punch, while the heating element may be a high power (watt) density, solid state, ceramic, resistant heating element (e.g., aluminum nitride or boron nitride heaters).

Infrared welded exterior panel assembly and process of making same

An exterior body panel assembly having a Class A painted surface, mold-in color or non-Class A surface, and process of infrared welding components of the assembly. Panels of the assembly are placed on a nesting structure and the inside half of the structures are brought together with the other for a fit check. Panels are separated and an infrared heating fixture then heats the various areas to be heated on the panels. The areas on the panels are heated depending on the thicknesses of the parts at each area and surface geometries to be welded. The parts are immediately clamped back together under pressure for joining and cooling of the joined surfaces in the clamped arrangement.

Pulse Welding Method and Welding Tool for Pulse Welding for a Medical Pack Formed As a Bag
20200009800 · 2020-01-09 ·

The invention relates to a welding tool and a method for pulse welding films of plastic for medical packs formed as bags. The invention generally provides for the film material that has been plastified during welding, and is consequently free-flowing, to be specifically displaced by increasing the sealing surface area. The displaced film material can for instance compensate for dimensional and form tolerances. At the same time, however, the strength of the welded seam region, which adjoins the interior space of the bag, is not reduced.

Metal-resin joining device
10518482 · 2019-12-31 · ·

A metal-resin joining device joins a thermoplastic resin plate (12) to a metal plate (13) by melting the resin plate (12) in contact with the metal plate (13) through heating an exposed face of the metal plate (13) by one-sided resistive heating. The metal-resin joining device has a center electrode (24a) that is brought in contact with the metal plate (13) and a peripheral electrode (24b) that is brought in contact with the metal plate (13) to annularly surround the center electrode (24a) and to which a current flows from the center electrode (24a) via the metal plate (13), wherein the peripheral electrode (24b) is made of a metal material having a higher electrical resistance than the center electrode (24a).
