Abstract
Abstract Apparatus for positioning and maintaining a substrate within a tire mold. The substrate receives an applique which is to be transferred to the sidewall of a tire during the curing process. The substrate is of steel construction and is adapted to engage a receiving member within a circumferential surface of the tire mold. The receiving member is magnetized to attract the steel substrate and to retain the substrate and its applique in proper registration with the sidewall of the tire during closure of the mold and the curing process. A lip or pins are provided in association with the retainer to assure proper registration of the applique-bearing substrate with the tire sidewall.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
47 words
Apparatus for securing an applique to a tire, comprising: a substrate maintaining said applique thereon; a tire curing mold for receiving the tire; and retaining means within said mold for making forceful securing engagement with said substrate, maintaining said substrate in a fixed position within said mold.
Claim 2
Dependent Claim
47 words
Apparatus for securing an applique to a tire, comprising: a substrate maintaining said applique thereon; a tire curing mold for receiving the tire; and retaining means within said mold for making forceful securing engagement with said substrate, maintaining said substrate in a fixed position within said mold.
Claim 3
Dependent Claim
15 words
The apparatus according to claim 1 wherein said substrate comprises a ring of rigid material.
Claim 4
Dependent Claim
24 words
The apparatus according to claim 2 wherein said substrate comprises a steel ring and said retaining means comprises a magnetized element within said mold.
Claim 5
Independent Claim
29 words
The apparatus according to claim3 wherein said magnetized element comprises an annular member circumferentially maintained about an inner surface of said mold and said annular member is selectively magnetized.
Claim 6
Dependent Claim
23 words
The apparatus according to claim 4 wherein said annular member is maintained within a recess within an inner circumferential surface of said mold.
Claim 7
Dependent Claim
54 words
'The apparatus according to claim 4 wherein said annular member has a lip extending about an outer edge thereof for registering said steel ring upon said annular member and which further includes a plurality of pins extending from said mold in juxtaposition to said annular member, said pins adapted to receive said steel ring.
Claim 8
Dependent Claim
54 words
The apparatus according to claim 4 wherein the force between said magnetized annular member and said steel ring exceeds a force of adherence between said substrate and said applique and the force between said magnetized annular member and said steel ring is less than the force of adherence between said substrate and said applique.
Claim 9
Dependent Claim
56 words
8 . Apparatus for imparting decorative designs to the sidewall of a tire, comprising: a substrate having a decal thereon; a tire curing mold; and means within said tire mold for receiving and forcefully retaining said substrate in registration within said mold and said means are selectively actuated to attain such forceful engaging of said substrate.
Claim 10
Dependent Claim
56 words
8 . Apparatus for imparting decorative designs to the sidewall of a tire, comprising: a substrate having a decal thereon; a tire curing mold; and means within said tire mold for receiving and forcefully retaining said substrate in registration within said mold and said means are selectively actuated to attain such forceful engaging of said substrate.
Claim 11
Dependent Claim
108 words
1 9. The apparatus according to claim 8 wherein said substrate comprises a steel ring and said means comprises a magnetized annular member received within a recess within said tire mold. said annular member has a lip on one edge thereof, said lip adapted to guide said steel ring into registered engagement with said annular member ; pins extending from said mold in juxtaposition to said annular member and positioned to receive and engage circumferential surfaces of said steel ring; and a force of engagement between said steel ring and said decal is less than a magnetic force of engagement between said steel ring and said annular member.
Claim 12
Dependent Claim
34 words
The apparatus according to claim 9 wherein a force of engagement between said steel ring and said decal is greater than a magnetic force of engagement between said steel ring and said annular member.
Claim 13
Dependent Claim
58 words
The apparatus according to claim 8 wherein said means comprises pins extending from a surface of said tire curing mold, said pins adapted to engage said substrate about a periphery thereof; and said substrate is of a material having a coefficient of thermal expansion allowing the substrate to expand and disengage from said pins upon heating said substrate.
