Filed:

Sep 27, 2000
Appl. No.:

09/670642
Inventors:

Michael R. Berrigan - Oakdale MN
James F. Dyrud - New Richmond WI
Stanley C. Erickson - Stillwater MN
Luther E. Erickson - Grant MN
Assignee:

3M Innovative Properties Company - St. Paul MN
International Classification:

B32B 526
US Classification:

442381, 442394, 442400, 442415, 442392, 442393, 428 77, 428157, 428171, 428172, 428189, 428190, 428191, 428192, 428193, 428213, 428218
Abstract:

Multilayer meltblown fibrous webs, as well as apparatus and methods of forming the webs. The webs are produced on a rotating collector that also moves parallel to its longitudinal axis. The webs are thus formed in a helical process, and the resulting tubular web is separated in a direction parallel to a helix angle. By separating the tubular web in a direction parallel to the helix angle, a flat multilayer meltblown fibrous web is provided that allows for incorporation of feathered edges formed during the articles manufacture.

Filed:

Nov 28, 2006
Appl. No.:

11/563827
Inventors:

Daniel Zillig - Cottage Grove MN, US
Subramanian Krishnan - St. Paul MN, US
William Kopecky - Hudson WI, US
Stanley Erickson - Scandia MN, US
Steven Ward - Omaha NE, US
James Breister - Oakdale MN, US
International Classification:

B05B 1/28
US Classification:

239290000
Abstract:

Multi-component liquid spray system including a shim having a first array of first passages and a second array of second passages are described. When the shim is positioned between the first and second die portions of a housing, a first array of first liquid conduits and a second array of second liquid conduits are formed. The first array of first liquid conduits and second array of second liquid conduits are aligned such that at least one of the second liquid conduits is interspersed between successive first liquid conduits. Methods of making such spray systems and methods of using them to produce both multi-component sprays and coated articles are also described.

US Patent:

20080003430, Jan 3, 2008
Filed:

Jun 28, 2006
Appl. No.:

11/427094
Inventors:

Bruce B. Wilson - Woodbury MN, US

James C. Breister - Oakdale MN, US
International Classification:

D02G 3/00
US Classification:

428375
Abstract:

Particulate-loaded polymer fibers along with methods and systems for extruding polymeric fibers are disclosed. The particulate-loaded polymer fibers have a fiber body that includes a polymeric binder with a plurality of particles distributed within the polymeric binder. Some of the particles are completely encapsulated within the polymeric binder and others may be embedded such that they are partially exposed on the outer surface of the fiber body. The polymers used in the fibers may be of high molecular weight and the encapsulated particles may be preferentially distributed towards the outer surfaces of the fibers.

International Classification:

B29C 5506
US Classification:

2642888
