Patent number: 11123229Abstract: 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.Type: GrantFiled: December 16, 2019Date of Patent: September 21, 2021Assignee: The Procter & Gamble CompanyInventors: Joseph Allen Eckstein, Hailing Bao, Robert Charles Dreisig, Howard Jay Kalnitz, Uwe Schneider

Patent number: 8905821Abstract: A rotary cutting apparatus comprises a frame and a die roll defining a first longitudinal axis and comprising a cutting member. The die roll is rotatably connected with the frame and configured to rotate about the first longitudinal axis. The rotary cutting apparatus further comprises a bearer ring connected with the die roll and an anvil roll defining a second longitudinal axis and comprising an outer radial surface. The anvil roll is rotatably connected with the frame and is configured to rotate about the second longitudinal axis. The bearer ring of the die roll is in contact with the outer radial surface. The rotary cutting apparatus further comprises a reconditioning member comprising an abrasive surface engaged with the outer radial surface of the anvil roll. The outer radial surface of the anvil roll moves relative to the abrasive surface.Type: GrantFiled: September 20, 2012Date of Patent: December 9, 2014Assignee: The Procter & Gamble CompanyInventors: Uwe Schneider, Robert Charles Dreisig

Patent number: 6105276Abstract: A limiting orifice through-air-drying medium for papermaking or other absorbent embryonic webs. The medium may be used in an apparatus which can be embodied in a cover and a roll. The medium has the unique combination of a relatively high bending fatigue strength and relatively low pressure drop. The medium may comprise a laminate of a plurality of plies. The intermediate plies of the laminate may be woven with a square weave. The medium may also be used for other types of drying.Type: GrantFiled: June 19, 1997Date of Patent: August 22, 2000Assignee: The Procter & Gamble CompanyInventors: Donald Eugene Ensign, Robert Charles Dreisig, Michael Gomer Stelljes, Jr., Wilbur Russell Knight
