Abstract
Abstract A product and process for imparting decorative appliques to the sidewalls of tires during the curing operation are presented. Rubber-based appliques are precured and maintained upon a substrate for application to the sidewall of the tire during the curing operation for the tire. The precure provides integrity and definition to the applique while the curing operation allows for complete and total bonding of the applique to the tire. Further, the applique is of such nature that it maintains its identity without deformation during the elevated temperatures and pressures incident to the curing operation. After cure, the substrate is stripped from the tire and applique, the result being a cured tire with a decorative sidewall.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
49 words
An assembly for applying decorative pieces to the sidewall of a tire during a molding and curing operation, comprising: a substrate; and an applique removably received upon said substrate, said applique being adapted for bonding to the sidewall of the tire by concurrent curing of the tire and applique.
Claim 2
Dependent Claim
49 words
An assembly for applying decorative pieces to the sidewall of a tire during a molding and curing operation, comprising: a substrate; and an applique removably received upon said substrate, said applique being adapted for bonding to the sidewall of the tire by concurrent curing of the tire and applique.
Claim 3
Dependent Claim
13 words
The assembly according to Claim l wherein said applique is an elastomeric material.
Claim 4
Dependent Claim
12 words
The assembly according to Claim 2 wherein said applique is partially precured.
Claim 5
Dependent Claim
19 words
The assembly according to Claim 3 wherein said applique is more completely precured internally than on external surfaces thereof.
Claim 6
Dependent Claim
22 words
The assembly according to Claim 3 wherein opposite surfaces of a cross section of said applique are of different degrees of precure.
Claim 7
Dependent Claim
28 words
The assembly according to Claim 5 wherein a surface of said applique adapted for contacting the tire has a lesser degree of cure than an opposite surface thereof.
Claim 8
Dependent Claim
45 words
The assembly according to Claim 6 wherein said substrate has a recess therein for receiving said applique, said precure of said applique being more complete in regions of said applique in contact with said substrate than in regions of said applique not in such contact.
Claim 9
Dependent Claim
17 words
The assembly according to Claim l wherein said substrate has a recess therein for receiving said applique.
Claim 10
Dependent Claim
22 words
The assembly according to Claim 8 wherein said recess has a depth which is less than half the thickness of said applique.
Claim 11
Dependent Claim
59 words
l0. A process for applying decorative pieces to a sidewall of a tire, comprising the steps of: forming an applique upon a substrate; positioning said applique and substrate upon a sidewall of said tire; curing said tire and applique with a tire press and thereby bonding said applique to said tire sidewall; and removing said substrate from said applique.
Claim 12
Dependent Claim
59 words
l0. A process for applying decorative pieces to a sidewall of a tire, comprising the steps of: forming an applique upon a substrate; positioning said applique and substrate upon a sidewall of said tire; curing said tire and applique with a tire press and thereby bonding said applique to said tire sidewall; and removing said substrate from said applique.
Claim 13
Dependent Claim
20 words
The process as recited in Claim l0 wherein said applique is formed by injecting an elastomeric material into a mold.
Claim 14
Dependent Claim
23 words
The process as recited in Claim ll wherein said substrate is placed into said mold prior to injection of said rubber-based material therein.
Claim 15
Dependent Claim
19 words
The process as recited in Claim l2 which further include the step of precuring said applique within said mold.
Claim 16
Dependent Claim
39 words
The process as recited in Claim l3 wherein said step of precuring is accomplished by the selective application of heat to various portions of said mold, to achieve different degrees of cure across a cross section of said applique.
Claim 17
Dependent Claim
28 words
The process as recited in Claim l4 wherein said substrate is maintained at a higher temperature than remaining portions of said mold in forming contact with said applique.
Claim 18
Dependent Claim
34 words
The process as recited in Claim l3 wherein said applique is precured by maintaining said rubber-based material in said mold at a temperature of 300-450°F for a time period respectively ranging between 85-20 seconds.
Claim 19
Dependent Claim
35 words
The process as recited in Claim l0 wherein said substrate is securedly received by said tire press and is stripped from the tire and applique upon termination of said curing and opening of said mold.
