Tire Tread Compounds Comprising Partially Crosslinked Natural Rubber

View page
US Patent:
5997673, Dec 7, 1999
Filed:
Sep 4, 1997
Appl. No.:
8/923545
Inventors:
Paul Harry Sandstrom - Tallmadge OH
Samson Samuel Apticar - Uniontown OH
William Paul Francik - Bath OH
David Allan Kindry - Clinton OH
Jerry Lawrence Brenner - Copley OH
Kevin James Pyle - Uniontown OH
Assignee:
The Goodyear Tire & Rubber Company - Akron OH
International Classification:
B29D 3006
B29D 3052
B60C 900
B60C 1100
US Classification:
1561101
Abstract:
In a tire having a tread with cap/base construction, a regulated amount of partially crosslinked natural rubber in a tire tread compound increases the uncured ("green") stiffness, tensile strength and tear resistance of a green compound used for the base without adversely affecting physical properties of the tread after it is cured. Such green stiffness is particularly useful in the construction of a tread for a pneumatic tire, which tread is of cap/base construction because stiffness provides requisite dimensional stability of both cap and base (in the tread) during the curing of the tire. The amount of partially crosslinked natural rubber used in a tread compound depends upon the extent of crosslinking in the natural rubber, the non-crosslinked remainder being virgin latex.

Pneumatic Tire Made By Butt-Splicing Structural Members And A Method Therefor

US Patent:
50624628, Nov 5, 1991
Filed:
Jan 19, 1990
Appl. No.:
7/467715
Inventors:
Grover W. Rye - Cuyahoga Falls OH
David A. Kindry - Clinton OH
Carolyn T. Weber - Mogadore OH
Assignee:
The Goodyear Tire & Rubber Company - Akron OH
International Classification:
B60C 902
B29D 3006
US Classification:
152548
Abstract:
The invention relates to a butt splicing technique for use in manufacturing reinforced elastomeric articles, in particular pneumatic tires. In the method, after a butt splice is made, a spun-bonded material is applied to the splice area as a splicing strip. The spun-bonded material has stress/strain/expansion characteristics that closely resemble such properties in an elastomeric component of the article which is spliced so that the splicing strip does not unduly distort the reinforcing structure of the component, while preventing opening of the splice during construction. Articles made using the method are also provided.
