A hybrid mold includes (a) an Invar® eggcrate structure, (b) an Invar® interim working surface and (c) a CF composite material overlay. The eggcrate and interim working surface are welded or otherwise connected together to form a unitary base mold. The CF overlay is bonded to the interim working surface. The CF overlay is easily reconfigurable and can be replaced without destroying the integrity of the base mold.

A respiratory apparatus may employ ultrasonic welds (410). The ultrasonic welding may be used to join a variety of headgear, mask and accessory components. This process may enhance comfort, fit and/or performance of the joined components and/or overall mask assembly. A component may be a single layer component such as a textile or fabric, or a composite or multiple layer component such as fabric and foam composites, or outer fabric layers (402-1) and inner spacer fabrics (402-3). Further, a component may be a strap, some other headgear component, a mask component, an accessory component or the like.
摘要:
A method for joining two objects by anchoring an insert portion provided on one of the objects in an opening provided on the other one of the objects. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. Before such liquefaction and interpenetration, an interference fit is established in which such opposite surfaces are pressed against each other, and, for the anchoring, mechanical vibration energy and possibly a shearing force are applied, wherein the shearing force puts a shear stress on the interference fit.

A cloth bonding apparatus (1) includes a base portion (2), a feed mechanism (17, 90), a nozzle (51), a nozzle support mechanism (41), and a guide member (70, 170, 270). The feed mechanism (17, 90) is adapted to feed, in a feed direction, an upper cloth (C2) and a lower cloth (C1) that are disposed on the base portion (2) while pressing the cloths (C2, C1). The nozzle (51) extends in an extending direction and is adapted to discharge adhesive, on an upstream side of the feed mechanism (17, 90) in the feed direction (C), between the upper cloth (C2) and the lower cloth (C1). The extending direction intersects the feed direction (C). The nozzle support mechanism (41) is adapted to support one end of the nozzle (51) in the extending direction. The guide member (70, 170, 270) includes a placement portion (71, 171, 271). The placement portion (71, 171, 271) is disposed above a top face of the base portion (2) and faces the nozzle (51) on a side of the other end of the nozzle (51) in the extending direction.
摘要:
Herein are disclosed apparatus and methods for impinging fluids, e.g. heated fluids, onto the surface of moving substrates and then locally removing the impinged fluid. The apparatus may comprise at least first and second fluid delivery outlets that are in diverging relation to each other. A long axis of the first fluid delivery outlet may be oriented obliquely to the path of the first moving substrate, and a long axis of the second fluid delivery outlet may be oriented obliquely to the path of the second moving substrate. The apparatus may comprise at least first and second fluid capture inlets that are locally positioned relative to the first and second fluid delivery outlets, respectively.

The present invention relates to a method and an apparatus for welding a 3D bellows, and a bellows, which is provided by: repeatedly laminating a unit cell material, a second adhesion-preventing film, a different unit cell material, and a first adhesion-preventing film, corresponding to the number of unit cells to be manufactured; forming ventilation holes on the unit cell materials by pressing a hole-processing cutter on which a hole-circumference welding heater is installed onto the laminated unit cell materials and the first adhesion-preventing films, and then heating the circumference of the ventilation holes, so that the surrounding area around the ventilation holes of two neighboring unit cell materials that are not blocked by the first adhesion-preventing film are mutually welded, finishing two sides of the unit cells by positioning, on two outermost surfaces of the laminated unit cell materials, a fist finishing unit cell material and a second finishing unit cell material provided with an air injection port; and cutting the first finishing unit cell material, the unit cell materials, and the second finishing unit cell material and heating the periphery of the cut area by pressing a contour-processing cutter, so that the surrounding area around the contours of two neighboring unit cell materials that are not blocked by the second adhesion-preventing film are mutually welded. Accordingly, a plurality of unit cells can be manufactured with two rounds of punching work, the unit cells can be conjoined, and the inside of the unit cells can be connected, thereby enabling mass production and significant reduction of manufacturing cost.
摘要:
The present invention is an absorbent structure comprising a fibrous matrix (110), meltfusionable material and superabsorbent polymer particles (140). The absorbent structure is bonded by a meltfusion bond point (200) pattern, which is preferably created by ultrasonic welding.
摘要:
A method for manufacturing a cushioning element (200) may include utilizing a die with a plurality of die elements positioned in a particular arrangement. A polymer material, which may be a polymer foam material, is located between the die and an extractor. The polymer material is compressed between the die and the extractor, and the die elements cut the polymer material to form a plurality of pad components (230), which are arranged like the die elements. The die and the extractor are separated, and the pad components are secured to the extractor in the arrangement of the die elements. Additionally, the pad components are bonded to at least one material layer (210, 220) such that the pad components remain in the arrangement of the die elements.
