Publication number: 20220314576Abstract: A composite fabric includes a nonwoven fabric layer having non-bonded areas and a structured film layer discontinuously bonded to the nonwoven fabric layer. The discontinuously bonded nonwoven fabric layer and the structured film layer share an overlapping area with at least one set of coincident bond sites. The discontinuously bonded nonwoven fabric does not have another bonding pattern in the overlapping area distinct from the at least one set of coincident bond sites. A method of forming a composite fabric is also described. The method includes forming a fiber layer including a mat of at least partially unconsolidated fibers, positioning a structured film layer and the fiber layer such that they overlap, and discontinuously bonding the mat into a discontinuously bonded nonwoven fabric while simultaneously bonding the structured film layer to the nonwoven fabric layer. An apparatus for forming a composite fabric is also described.Type: ApplicationFiled: June 14, 2022Publication date: October 6, 2022Inventors: Thomas J. Gilbert, Shou-Lu G. Wang, Neelakandan Chandrasekaran, Todd L. Nelson, Stanley Rendon, Mark A. Peltier, Michael R. Berrigan, Jerald W. Hall, JR., Stephen M. Sanocki, Daniel E. Johnson, Bernard G. Rolstad, Ibrahim S.

Patent number: 7591058Abstract: Nonwoven fibrous webs including amorphous polymeric fibers with improved and/or more convenient bondability are disclosed. The nonwoven fibrous webs may include only amorphous polymeric fibers or they may include additional components in addition to amorphous polymeric fibers. The amorphous polymeric fibers within the web may be autogeneously bonded or autogeneously bondable. The amorphous polymeric fibers may be characterized as varying in morphology over the length of continuous fibers so as to provide longitudinal segments that differ from one another in softening characteristics during a selected bonding operation.Type: GrantFiled: June 14, 2007Date of Patent: September 22, 2009Assignee: 3M Innovative Properties CompanyInventors: Michael R. Berrigan, Anne N. De Rovere, William T. Fay, Jerald W. Hall, Jr., Pamela A. Percha

Patent number: 7204365Abstract: An assembly and method for cleaning a conveyor belt system is disclosed. The cleaning assembly is for removing liquids and solids from an endless conveyor belt, the assembly includes a plurality of laterally extending liquid absorbent material sheets disposed adjacent the belt, with the sheets collectively defining a contact face that is engageable with the belt for wiping liquids from the belt.Type: GrantFiled: September 6, 2006Date of Patent: April 17, 2007Assignee: 3M Innovative Properties CompanyInventors: Lance E. Behymer, Smarajit Mitra, Jerald W. Hall, Jr., Alexander C. Tsuei

Patent number: 7140495Abstract: Described is an apparatus for the removal of organic substances and/or nitrogen sources from an aqueous medium by exposing the aqueous medium to the action of microorganisms supported on a gas permeable, water impermeable layer, or on and/or in a three dimensional microbial support layer, that is proximate a gas delivery layer through which gas, preferably, oxygen-containing gas, is supplied to the gas permeable layer such that it diffuses through the gas permeable layer and is supplied to the microorganisms.Type: GrantFiled: December 14, 2001Date of Patent: November 28, 2006Assignee: 3M Innovative Properties CompanyInventors: Jonathan F. Hester, Brian E. Spiewak, David R. Holm, Jerald W. Hall, Jr., Seth M. Kirk, Moses M. David, Brinda B. Lakshmi

Patent number: 7055675Abstract: An assembly for cleaning a conveyor belt system is disclosed. The cleaning assembly is for a conveyor belt system with the type having first and second endless belts which each traverse a separate belt travel path and together define a generally upright article transport path between opposed top faces of the belts. The cleaning assembly includes a belt wiping blade assembly for moving liquids and debris from a belt, an absorbent material downstream from the blade assembly for wiping excess liquid from the belt, and belt edge seals disposed between the opposed top faces of the belts along the article transport path.Type: GrantFiled: December 4, 2002Date of Patent: June 6, 2006Assignee: 3M Innovative Properties CompanyInventors: Lance E. Behymer, Smarajit Mitra, Jerald W. Hall, Jr., Alexander C. Tsuei
