Appl. No.:

10/444166

Inventors:

Ramendra Nath Majumdar - Hudson OH
Joseph Padovan - Akron OH
Marvin Wayne Tipton - Akron OH
Douglas Blair Dotts - Mogadore OH

Assignee:

The Goodyear Tire Rubber Company - Akron OH

International Classification:

B60C 100

US Classification:

1522096, 152541, 156 96

Abstract:

The present invention relates to preparation an article of manufacture, such as of a tire, via application of at least one partially pre-cured component. Tires are often prepared with pre-cured, pre-shaped components such as for example, application of pre-cured tread strips to a cured carcass as in the case of re-treaded tires. Thus precured tread and cured carcass are joined together using a cushion gum followed by heating the resulting assembly at an elevated temperature to cure the cushion gum. Such pre-cured component may also be, for example, a sidewall apex. In such cases, the pre-cured component is subjected to more heat than is necessary which may be detrimental for the component. This invention is directed to the use of a partially pre-cured component to prepare a tire assembly prior to the curing of the entire components of the tire assembly.

Joseph Padovan - Akron OH, US

International Classification:

G01N003/30

US Classification:

073/012010

Abstract:

The present invention generally relates to a tensile impact apparatus that is designed to give dynamic stress-strain curves and fracture characteristics for a rubber specimen undergoing tensile impact loading. More particularly, this invention relates to a tensile impact apparatus that is capable of achieving strains of up to fracture. The apparatus is also capable of visually recording fracture phenomena.
