US 2025/0128486 A1 · TIRE FLAT PROOFING TIRE FILLING METHOD

Abstract

Methods and systems are contemplated in which elastomer materials can be processed into flatproofing materials which may be used to produce flatproofed tires. A elastomer material can be extruded through an extrusion die to produce two or more elastomer chunks. These elastomer chunks can be ground into a granulated material, which may comprise a flatproofing material to be used to fill a tire. Air in the tire may escape through a hole in the tire, and this air can be guided through a vent wherein an air flow meter can measure the air's flow rate. If the measured air flow rate drops below a threshold value, the process of filling the tire with the flatproofing material can be ceased. The tire can be investigated, after which the tire may be further filled with the flatproofing material before sealing the hole in the tire to produce the flatproofed tire.

Dependent claims

A method of producing a flatproofed tire, the method comprising the steps of:

a) extruding an elastomer material through an extrusion die to produce two or more elastomer chunks;
b) grinding the two or more elastomer chunks to produce a granulated material;
c) at least partially filling a tire with at least some of the granulated material, the tire having an internal volume containing air, the filling of the tire with the at least some of the granulated material causing at least some of the air to escape from the tire through a hole in the tire;
d) measuring the flow rate of at least some of the air escaping from the tire;
e) ceasing the filling of the tire with the at least some of the granulated material;
and
f) sealing the hole in the tire;
wherein the step of ceasing the filling of the tire with at least some of the granulated material is performed after the measured flow rate of the air escaping from the tire drops below a threshold value.

A flatproofed tire system for recycling an elastomer material and producing a flatproofed tire, the flatproofed tire system comprising an extrusion system, the extrusion system comprising:

a piston, the piston being movable in at least a direction of extrusion;
and
an extrusion die having one or more edges defining one or more voids therebetween;
the piston being operative to extrude the elastomer material through the extrusion die when the piston is moved in the direction of extrusion, the extrusion of the elastomer material through the extrusion die producing two or more elastomer chunks, the two or more elastomer chunks being operative to be received by a grinder to produce a granulated material;
the flatproofed tire system further comprising a tire filling system, the tire filling system comprising:
a housing having an opening;
and
a duct having a passageway, the duct being operative to be coupled to the housing, the coupling of the duct to the housing being associated with the opening in the housing so that the passageway of the duct is fluidly connected to the opening of the housing, the duct further being operative to be coupled to a tire having an internal volume containing air, the coupling of the duct to the tire being associated with a hole in the tire so that the passageway of the duct is fluidly connected to the internal volume of the tire to provide a fluid pathway for the air contained in the tire to escape from the tire and into the passageway.
