Patent number: 5562790Abstract: An apparatus and method for bonding at least two continuously moving substrate webs together is disclosed. The apparatus comprises a rotatable bonding roll which is located adjacent the substrate webs and configured to rotate about a bonding axis. A rotatable anvil roll has an anvil surface and is configured to rotate about an anvil axis to press the substrate webs against an outer peripheral bonding surface of the bonding roll thereby bonding the substrate webs together. The anvil roll is pivotally connected to a pivotal support mechanism which is configured to maintain the anvil surface in a substantially parallel relationship with the bonding surface. The pivotal support mechanism is configured to allow the anvil roll to pivot such that the anvil roll maintains a substantially constant force on the bonding surface of the bonding roll across the width of the anvil roll.Type: GrantFiled: May 18, 1995Date of Patent: October 8, 1996Assignee: Kimberly-Clark CorporationInventors: Thomas D. Ehlert, Norman R. Stegelmann

Patent number: 5096532Abstract: An ultrasonic rotary horn intended to be excited at a frequency of from about 18 to about 60 kHz, which horn is a shaped, solid metal object having a rotational axis and a radial surface terminated by a first end and a second end. The diameter of the horn can vary from about 4 cm to about 19 cm. The width of the horn at the radial surface is in the range of from about 0.6 cm to about 13 cm. The thickness of the horn at its rotational axis is from about 0.6 cm to about 15 cm and is independent of the width of the horn at the radial surface. The horn has a mass in the range of from about 0.06 kg to about 30 kg.Type: GrantFiled: May 18, 1990Date of Patent: March 17, 1992Assignee: Kimberly-Clark CorporationInventors: Joseph G.
