Abstract
Abstract A machine or apparatus for coating, heating or drying fibers in a continuous length element; a machine for impregnating such fiber with a liquid fiber-to-rubber adhesive coating in the manufacture of rubber products; or an apparatus wherein the element is heated and heat products are removed from said element by a gas stream rapidly moving over the surface of said element, wherein said heat products are evaporated water molecules for rapidly drying the element, heat, or other products resulting from heating this element.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
148 words
An apparatus for drying a fluid treated continuous yarn or fabric fiber, comprising in combination: a. a heating zone having a gas discharge and gas exhaust in vertical spaced relation; b. a gas-fired heater with exposed flames for generating infrared radiation, disposed in the heating zone intermediate the gas discharge and gas exhaust; c. means for moving a continuous fiber vertically past the heater adjacent the gas discharge and gas exhaust; d. means for discharging a continuous stream of gas, under pressure, from the gas discharge towards the gas exhaust during operation of the heater; and e. means in fixed, unmovable relation to the heater, for channeling the gas stream adjacent and in contacting relation with the moving fiber and out of interfering relation with the exposed flames of the heater, such that the stream of gas helps dry the fiber without adversely affecting operation of the heater.
Claim 2
Independent Claim
148 words
An apparatus for drying a fluid treated continuous yarn or fabric fiber, comprising in combination: a. a heating zone having a gas discharge and gas exhaust in vertical spaced relation; b. a gas-fired heater with exposed flames for generating infrared radiation, disposed in the heating zone intermediate the gas discharge and gas exhaust; c. means for moving a continuous fiber vertically past the heater adjacent the gas discharge and gas exhaust; d. means for discharging a continuous stream of gas, under pressure, from the gas discharge towards the gas exhaust during operation of the heater; and e. means in fixed, unmovable relation to the heater, for channeling the gas stream adjacent and in contacting relation with the moving fiber and out of interfering relation with the exposed flames of the heater, such that the stream of gas helps dry the fiber without adversely affecting operation of the heater.
Claim 3
Dependent Claim
23 words
The apparatus of claim 1, which includes: means for exhausting gas, laden with heat products generated by the heater, through the gas exhaust.
Claim 4
Dependent Claim
16 words
The apparatus of claim 1, wherein the gas stream and fiber move in the same direction.
Claim 5
Dependent Claim
18 words
The apparatus of claim 1, wherein the gas exhaust is in vertical spaced relation above the gas discharge.
Claim 6
Dependent Claim
32 words
The apparatus of claim 1, wherein the gas channeling means includes a deflector adjacent the gas discharge for engaging gas passing under pressure therefrom and directing the gas towards the moving fiber.
Claim 7
Dependent Claim
26 words
The apparatus of claim 5, wherein the deflector includes a configured plate coextensive with the gas discharge and converging in a direction towards the moving fiber.
Claim 8
Dependent Claim
27 words
The apparatus of claim 6, wherein the gas includes air discharged from the gas discharge at the rate of about 1,000 to about 2,000 feet per minute.
Claim 9
Dependent Claim
25 words
The apparatus of claim 7, wherein the quantity of air discharged from the gas discharge is not more than about 1,500 cubic feet per minute.
Claim 10
Independent Claim
95 words
A method for processing a tire cord, comprising the steps of: a. coating a tire cord with liquid adhesive for increasing the adhesion between the tire cord and rubber material used in the production of tires; b. moving the liquid coated tire cord past exposed flames of a plurality of gas fired infrared heaters disposed in vertical stacked relation to dry the adhesive coating; and c. simultaneously contacting the tire cord with successive streams of gas, under pressure, as the cord moves past the exposed flames of the heaters, to help dry the adhesive coating.
Claim 11
Independent Claim
95 words
A method for processing a tire cord, comprising the steps of: a. coating a tire cord with liquid adhesive for increasing the adhesion between the tire cord and rubber material used in the production of tires; b. moving the liquid coated tire cord past exposed flames of a plurality of gas fired infrared heaters disposed in vertical stacked relation to dry the adhesive coating; and c. simultaneously contacting the tire cord with successive streams of gas, under pressure, as the cord moves past the exposed flames of the heaters, to help dry the adhesive coating.
Claim 12
Dependent Claim
38 words
The method of claim 9, which includes: removing as much gas as possible from each gas stream after the gas scrubs the tire cord and becomes at least partially ladened with heat products generated by the infrared heaters.
Claim 13
Dependent Claim
29 words
The method of claim 10, which includes: channeling the streams of gas adjacent the moving tire cord out of interfering relation with the exposed flames of the infrared heaters.
Claim 14
Dependent Claim
28 words
The method of claim 11, which includes: moving the tire cord between exposed flames of opposing pairs of infrared heaters to heat the cord from opposing sides thereof.
Claim 15
Dependent Claim
20 words
The method of claim 12, wherein different streams of gas are used for every infrared heater the tire cord passes.
Claim 16
Dependent Claim
30 words
The method of claim 13, wherein the streams of gas are discharged towards the moving tire cord at a rate of from about 1,000 to about 2,000 feet per minute.
Claim 17
Dependent Claim
28 words
The method of claim 14, wherein each stream of gas after contacting the moving tire cord moves in a direction generally parallel to the tire cord until removed.
