Apparatus and Method for Continuously Attaching a Primary Substrate to a Secondary Substrate to Form a Product Having Indicia Thereon
In one embodiment, a method of attaching one substrate to another substrate includes supplying a first substrate having an indicium thereon from a first source, supplying a second substrate from a second source, wherein the supplying is accomplished in a continuous manner, and curing the substrates until the substrates are bonded thereto to form a product. The method and apparatus disclosed herein allows a fabric to be integrally bonded to either an elastomeric composition or a urethane composition utilizing a continuous process. The product includes indicium that identifies or conveys information about the product.
1 . A method of attaching two substrates, comprising:
supplying a first substrate from a first source, wherein the first substrate is a fabric having an indicium thereon;
supplying a second substrate from a second source; and
curing the substrates until the substrates are bonded to each other to form a product, wherein the indicium is visible on the product.
2 . The method of claim 1 , wherein the second substrate is an elastomeric composition.
3 . The method of claim 1 , wherein the second substrate is a urethane composition.
4 . The method of claim 1 , wherein the first substrate is a braid.
5 . The method of claim 1 , wherein the first and second substrates are bonded thereto to form a substantially unitary product.
6 . The method of claim 1 , wherein the curing is accomplished through heating from a platen heating system.
7 . The method of claim 6 , wherein the platen heating system includes plates disposed adjacent a conveyor to heat the second substrate.
8 . The method of claim 1 , wherein the first and second substrates are attached to each other in a continuous manner.
9 . An apparatus for continuously attaching a first substrate to a second substrate, comprising:
a first substrate supply source that continuously dispenses a first substrate onto a top surface of a second substrate, wherein the first substrate includes an indicium thereon;
a second substrate supply source that continuously dispenses the second substrate onto a conveyor;
a secondary conveyor system that presses the first substrate into the second substrate; and
a heating mechanism that heats the first substrate and the second substrate, wherein the first substrate is vulcanized to the second substrate to form a product having a substantially smooth surface and wherein the indicium is visible on the surface.
10 . The attaching apparatus of claim 9 , wherein the first substrate is a braid.
11 . The attaching apparatus of claim 10 , wherein the first substrate is a fabric.

13 . The attaching apparatus of claim 9 , wherein the heating occurs for a time period between about 4 minutes and about 10 minutes.
14 . The attaching apparatus of claim 9 , wherein a substantially permanent bond is formed between the first substrate and the second substrate.
15 . The attaching apparatus of claim 9 , wherein the product is cooled for a period of time less than about a minute after entering a cooling zone.
16 . The attaching apparatus of claim 9 , wherein the second substrate is an elastomeric composition.
17 . The attaching apparatus of claim 16 , wherein the elastomeric composition comprises about 20% to about 40% rubber, about 40% to about 60% fillers, about 2% to about 10% process oil, and about 5% to about 15% other additives.
