Patent number: 7704341Abstract: In a method and apparatus for forming a bonded web comprised at least in part of a polyester, a first material web and a second material web are arranged in opposed relationship with each other at least along those portions of the first and second material webs to be bonded together. At least one of the first and second material webs is comprised at least in part of the polyester. The opposed webs are transported in a machine direction to the nip of a bonding apparatus comprised of a first bonding member and a second bonding member defining the nip therebetween for passage of the opposed first and second material webs therebetween in the machine direction. A shear force is applied to the webs generally in the machine direction at the nip and the webs are mechanically bonded together at the nip while the shear force is applied to webs.Type: GrantFiled: December 15, 2005Date of Patent: April 27, 2010Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Vasily Aramovich Topolkaraev, Barton Andrew Laughlin, John Ford Condron, Patrick Martin Downey, Thomas David Ehlert, Dennis Y.

Patent number: RE42330Abstract: A laminating apparatus includes a roller, an electro-heating shaft, a power transmitting and resilient member and a power transmitting and securing member. The roller is in contact with a thin film, moves through the thin film to heat and laminate the thin film to a sheet material. The electro-heating shaft is wrapped by the roller, transforms electric energy into thermal energy to heat the thin film, and drives rotation of the roller to move through the thin film. The power transmitting and resilient member is in contact with an axial end surface of the electro-heating shaft in an axial direction of the electro-heating shaft for transmitting electricity from a power source to the electro-heating shaft. The power transmitting and securing member is coupled to the electro-heating shaft for compressing the power transmitting and resilient member therebetween, thereby continuously transmitting the electricity from the power source to the electro-heating shaft via the power transmitting and securing member.Type: GrantFiled: July 10, 2007Date of Patent: May 10, 2011Assignee: Transpacific Plasma, LLCInventor: Shin-Fu Lin
