  • Patent number: 10647079
    Abstract: In a method of ultrasonically bonding paperboard, first and second pieces of paperboard are supplied, with at least one of the first and second pieces of paperboard being provided with a clay coating. The first and second pieces of paperboard are moistened and positioned in a gap between a sonotrode and an anvil of an ultrasonic welding unit. The ultrasonic welding unit is activated and the first and second pieces of paperboard are compressed between 30-70%, more preferably between 40-60%, to cause the clay coating to mobilize and force the clay coating material into fiber matrixes of the first and second pieces of paperboard, followed by cooling of the first and second pieces of paperboard, to bond the first and second pieces of paperboard.

  • Patent number: 10443496
    Abstract: Systems and methods are provided for acoustic paneling. One embodiment is a method for fabricating an acoustic panel. The method includes receiving a sheet of thermoplastic paper, stamping/conforming the sheet into rows that each comprise a three dimensional shape, and transforming the sheet into a multi-celled core. Transforming the sheet includes identifying fold lines separating the rows, folding the sheet at the fold lines in a pleat fold, thereby uniting upper surfaces of adjacent rows and uniting lower surfaces of adjacent rows; and compressing the rows of the folded sheet together in the presence of heat, causing adjacent rows to fuse together into cells. The method further includes applying a backing sheet to the core, and applying a facesheet to a surface of the core that includes openings which direct a portion of airflow across the facesheet into the cells, resulting in acoustic control.

    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.

    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.

  • Patent number: 8357256
    Abstract: The present invention relates to a process for the manufacture of a three-dimensional nonwoven, a manufacturing line for implementing this process and the resulting three-dimensional nonwoven product. Process characterized in that it consists in using a folding element (5) to apply, to an incoming web containing a proportion of thermoplastic fibers and/or filaments or fixing material, an initial fixing of the fold of the incoming web in the form of peaks and troughs, brought about by blades extending radially on ends of the folding element (5), this initial fixing being applied either by maintaining the folding element (5) itself at a set temperature, or by heating the incoming web. The invention is more particularly applicable to the textile industry, especially the manufacture of nonwovens.

  • Publication number: 20120244311
    Abstract: A nonwoven industrial fabric, and a method of constructing the fabric. The fabric comprises at least one layer of a polymeric film having a plurality of apertures extending from an upper surface through to a lower surface. Adjacent pairs of the apertures define land areas therebetween, and selected land areas comprise protrusions extending from at least one of the upper surface and the lower surface of the layer to form a profile to the respective surface. The method comprises optionally pre-embossing the film, cutting the film to provide the plurality of apertures, applying pressure to selected land areas to form the protrusions to create a contoured profile, and treating the film to set the contoured profile. Additional surface treatment can be provided, and two or more layers can be secured over each other for multilayer fabrics. The invention provides a simplified and economical construction, while maintaining stability and strength.

  • Patent number: 8241454
    Abstract: In a corrugating machine and a method of producing corrugated cardboard, provision is made for a marking device by means of which a color mark is applied by rubbing off a solid coloring agent, the color mark being detected by means of a detection device in order to easily and precisely mark and cut out joining points. The applied and detected color mark enables a web length of a web of single-faced corrugated cardboard in a storage device to be determined, thus allowing an electronic control device to operate a cross-cutting device in an easy and precise manner.

    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 mattress, partition panels, other furniture and construction products.

  • Patent number: 8057621
    Abstract: A method and apparatus are useful to produce a corrugated product. They can be used to produce a corrugated product at low temperature, such as room temperature. A zero-contact roll is used to support a web of medium material on a cushion of air at a location prior to the web entering the corrugating labyrinth. The web is free to move toward or away from the surface of the zero-contact roll, on the cushion of air, in response to small oscillatory changes in downstream tension demand based on the fluting frequency in the corrugating labyrinth. A mechanism is also provided to precisely control the mean tension in the web prior to entering the corrugating labyrinth at a low value. Thus, mean web tension is precisely controlled and is low, tension oscillations can be damped, and low temperature corrugating can be achieved without significant fracturing in the corrugated web. A single-facer useful to apply a high-solids content adhesive, also desirable for low-temperature corrugating, is also provided.
