8/444074

Inventors:

Gary L. Holmes - Vadnais Heights MN
Scott R. Culler - Burnsville MN
David H. Hardy - New Richmond WI
William A. Hendrickson - St. Joseph WI
Thomas P. Klun - Lakeland MN
Kimberly K. Harmon - Hudson WI
Robert V. Heiti - Hudson WI

US Patent:

56907052, Nov 25, 1997

Filed:

Jun 24, 1996

Appl. No.:

8/673456

Inventors:

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

B24B 100

US Classification:

51295

Abstract:

Precisely shaped composites and methods for making these composites are disclosed. The method of this invention comprises the steps of: (a) providing a production tool having a plurality of cavities; (b) providing a dispensing means capable of introducing a binder precursor comprising a thermosetting resin into the cavities; (c) providing a means, within a curing zone, for at least partially curing the binder precursor; (d) introducing the binder precursor into at least a portion of at least two of the cavities; (e) continuously moving the production tool through the curing zone to at least partially cure the binder precursor to provide a solidified, handleable binder; (f) removing the binder from said at least one cavity; and (g) converting the binder into precisely shaped composites. Steps (f) and (g) can be conducted simultaneously. The composites are bonded to a backing to form a coated abrasive article.

US Patent:

55499627, Aug 27, 1996

Filed:

Jun 30, 1993

Appl. No.:

8/085638

Inventors:

Gary L. Holmes - Vadnais Heights MN
Scott R. Culler - Burnsville MN
David H. Hardy - New Richmond WI
Kimberly K. Harmon - Hudson WI
Robert V. Heiti - Hudson WI
William A. Hendrickson - St. Joseph WI
Thomas P. Klun - Lakeland MN
Kathryn M. Spurgeon - River Falls WI
Charles J. Studiner - Oakdale MI

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

D06N 704

US Classification:

428144

Abstract:

A coated abrasive article comprising: (a) a backing; (b) at least one layer comprising a plurality of precisely shaped abrasive particles that comprise abrasive grits and a free-radically polymerized binder, wherein said precisely shaped particles have vertexes and (c) a bonding medium which serves to adhere said precisely shaped particles to said backing; wherein the precisely shaped particles are randomly disposed on the backing such that at least a portion of said particles are oriented with said vertexes pointing toward said backing.

Abrasive Articles Comprising Precisely Shaped Particles

US Patent:

55002730, Mar 19, 1996

Filed:

May 19, 1995

Appl. No.:

8/445364

Inventors:

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

D06N 704

US Classification:

428147

Abstract:

Abrasive articles comprising precisely shaped particles are disclosed. The particles are bonded together to form a shaped mass, e. g. , a wheel; alternatively, the particles can be bonded to a backing to form a coated abrasive article; or the particles can be bonded into a fibrous, nonwoven substrate to form a non-woven abrasive article.
