  • Patent number: 12121100
    Abstract: An article of footwear has a sole structure that includes a bladder having stacked polymeric sheet secured to one another at a peripheral bond and defining a first sealed chamber between the first and second polymeric sheets, a second sealed chamber between the second and third polymeric sheets, and a third sealed chamber between the third and fourth polymeric sheets, each of the first, second, and third sealed chambers retaining fluid in isolation from one another. Different patterns of bonds secure adjacent ones of the polymeric sheets to one another, resulting in different geometries of the sealed chambers. The sealed chambers are configured (e.g., by pressure, shape, position, and/or size) to elastically deform to provide a desirable cushioning experience.

  • Patent number: 11370159
    Abstract: A flexible punch and die are used to form a flat composite laminate charge into a stiffener having a desired cross sectional shape. A desired contour is formed in the stiffener by bending the punch and die. Ply wrinkling is avoided during contouring by maintaining those portions of the stiffener subject to wrinkling in tension as the contouring is being performed. Bridging of the plies during the contouring process is avoided by first contouring those sections of the stiffener that are subject to wrinkling, and then contouring the remaining sections of the stiffener.

  • Patent number: 11298768
    Abstract: A method of preparing a surface for diffusion bonding comprises contacting a binder material with a discontinuous surface comprising surface regions separated by gaps. The binder material is selectively deposited onto the surface regions and has a sufficient viscosity to form a self-supporting layer without flowing into the gaps. The self-supporting layer of binder material comprises a mass density in a range from about 0.001 g/in2 to about 0.050 g/in2. A braze powder is distributed over the self-supporting layer of binder material, and a predetermined amount of the braze powder is attached to the binder material. The discontinuous surface is then heated to remove the binder material and adhere the braze powder to the discontinuous surface. Thus, a prewet surface with a braze deposit thereon is formed.

    Abstract: The present disclosure relates to methods and apparatuses for mechanically bonding substrates together. The apparatuses may include a pattern roll including a pattern element protruding radially outward. The pattern element includes a pattern surface and includes one or more channels adjacent the pattern surface. The pattern roll may be positioned adjacent an anvil roll to define a nip between the pattern surface and the anvil roll, wherein the pattern roll is biased toward the anvil roll to define a nip pressure between pattern surface and the anvil roll. As substrates advance between the pattern roll and anvil roll, the substrates are compressed between the anvil roll and the pattern surface to form a discrete bond region between the first and second substrates. As such, during the bonding process, some yielded substrate material flows from under the pattern surface and into the channel to form a channel grommet region.

  • Publication number: 20140138018
    Abstract: A film material formed of thermoplastic polymer material is processed so as to have linearly extending regions (A) linked together by linearly extending webs (B), regions (A) and webs (B) each being oriented, the dominant direction of orientation in regions (A) forming an angle (V) to the direction on which (A) extends and webs (B) comprising arrays of linear furrows of thinner material or splits forming angles (U) higher than (V) to the direction in which (A) extends. The method of producing the new film involves passing an orientated film through a pair of intermeshing grooved rollers to cold-stretch the film in a direction at an angle to the predominant original orientation, at least one of the grooved rollers having crests with sharp edges to form the division between regions A and webs B and to stretch the material to form webs B while stretching the material less or not at all to form regions A. Preferably at least one of the grooved rollers has crests with a waved surface shape.

    Abstract: The invention describes a device and method for making corrugated products. The device can be used with any substrate and includes, at least, first and second drive rollers for driving a middle substrate and a single wall corrugated product. In other embodiments the invention includes upper drive rollers, lower drive rollers and middle drive rollers for driving an upper substrate, a lower substrate and a middle substrate. The middle substrate is driven between the upper and lower substrates at a higher velocity to form flutes that are anchored between the upper an lower substrates thereby forming a corrugated product. The invention also provides for customized corrugated products having multiple fluted substrates in various desirable arrangements. Examples of such products include mattresses, partition panels, other furniture, construction products such as tubes or pipes previously made from metals or concrete.

  • Patent number: 8714223
    Abstract: The machine for producing a corrugated board includes a first corrugating roller (3) and a second corrugating roller (5) defining a corrugating nip (7) through which a first web material (N1) passes. A gluing unit (9) applies a glue on crests of the first web material (N1) formed in the corrugating nip (7). A pressing member (11) cooperates with the second corrugating roller (5) to press a second web material (N2) against the crests of the first web material (N1). A pressure regulating system adjusts the pressure of the pressing member (11) against the second corrugating roller (5). At least a first pressure chamber (27C), which contains a pressure liquid and a pressure transducer, is associated with a first abutment (33) for said pressing member (11). A control unit (69) opens a stop valve (39) when the pressure detected by the pressure transducer (37) is outside a tolerance range.

  • Patent number: 8574383
    Abstract: A corrugator includes a separation sensor for sensing separation of a corrugated medium and liner of a corrugated paperboard. Sensing the separation, also known as blowout or fluff out, allows the corrugator to be controlled to prevent problems which arise when corrugated paperboard having such a separation continues downstream along the corrugator. Typically, the corrugator is operated to cease downstream movement of the paperboard while a faulty segment which includes the separation is removed and the problem causing the separation is fixed, thereby providing for subsequent production of corrugated paperboard which is properly glued.
