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: 14
Claim 1
Independent Claim
57 words
Apparatus for securing an applique to a tire, comprising: a ring maintaining said applique thereon; a tire curing mold for receiving the tire; and a magnetized element within said mold for making forceful securing engagement with said ring, maintaining said ring in a fixed position within said mold by magnetically attracting said ring to said magnetized element.
Claim 2
Dependent Claim
57 words
Apparatus for securing an applique to a tire, comprising: a ring maintaining said applique thereon; a tire curing mold for receiving the tire; and a magnetized element within said mold for making forceful securing engagement with said ring, maintaining said ring in a fixed position within said mold by magnetically attracting said ring to said magnetized element.
Claim 3
Dependent Claim
23 words
The apparatus according to claim 1 wherein said magnetized element comprises an annular member circumferentially maintained about an inner surface of said mold.
Claim 4
Dependent Claim
13 words
The apparatus according to claim 2 wherein said annular member is selectively magnetized.
Claim 5
Dependent Claim
23 words
The apparatus according to claim 2 wherein said annular member is maintained within a recess within an inner circumferential surface of said mold.
Claim 6
Dependent Claim
27 words
The apparatus according to claim 2 wherein said annular member has a lip extending about an outer edge thereof for registering said ring upon said annular member.
Claim 7
Dependent Claim
30 words
The apparatus according to claim 2 which further includes a plurality of pins extending from said mold in juxtaposition to said annular member, said pins adapted to receive said ring.
Claim 8
Dependent Claim
28 words
The apparatus according to claim 2 wherein the force between said magnetized annular member and said ring exceeds a force of adherence between said ring and said applique.
Claim 9
Dependent Claim
30 words
The apparatus according to claim 2 wherein the force between said magnetized annular member and said ring is less than the force of adherence between said ring and said applique.
Claim 10
Dependent Claim
90 words
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, said means comprising pins extending from a surface of said tire curing mold, said pins adapted to engage said substrate about a periphery thereof, said substrate being of a material having a coefficient of thermal expansion allowing the substrate to expand and disengage from said pins upon heating said substrate.
Claim 11
Dependent Claim
90 words
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, said means comprising pins extending from a surface of said tire curing mold, said pins adapted to engage said substrate about a periphery thereof, said substrate being of a material having a coefficient of thermal expansion allowing the substrate to expand and disengage from said pins upon heating said substrate.
Claim 12
Dependent Claim
13 words
The apparatus according to claim 9 wherein said substrate comprises a steel ring.
Claim 13
Dependent Claim
32 words
The apparatus according to claim 10 wherein said pins each have a head at one end thereof and which are characterized by a notch beneath said head, said notch receiving said substrate.
Claim 14
Dependent Claim
19 words
The apparatus according to claim 11 wherein three pins are provided for engagement about said periphery of said substrate.
