Tire and method for manufacturing tire

Abstract

A method of manufacturing a non-marking antistatic tire (5) in a more controlled manner, said method comprising the following successive steps: - manufacturing a preparatory tire comprising a first layer (1) and being manufactured from a first material, - adding An electrically conductive material (16), which has an electrical resistance less than that of the first layer (1), extends from the inner circumferential surface (11) of the first layer (1) towards the outer circumferential surface (10) such that the electrically conductive material ( 16) Conductive means (15) electrically connectable to the wheel (4), wherein conductive material (16) is added along at least one of the opposing tire sidewalls (21) of the prepared tire (5). The invention also relates to a tire (5) for a vehicle wheel comprising conductive means (15).

Description

technical field [0001] The invention relates to a method for manufacturing a solid tire according to the preamble of the first claim. The invention also relates to a tire. Background technique [0002] It is known from the prior art to manufacture the tread surface of a solid tire which is in contact with the ground on which the tire travels, comprising a non-marking material which can be cured or cured to avoid unwanted tire tracks on the ground surface. Tires made of rubber containing carbon black often leave black marks as they move across the ground. These traces are particularly undesirable where, for example, high hygiene requirements are imposed, for example in areas where food is handled. It is also known from the prior art that markings of the floor can be avoided by replacing, for example, silicon-based mixtures for conventional treading surface mixtures comprising carbon black, resulting in a more marking-free material. [0003] However, tires having a tread su...

Problems solved by technology

However, there is no way to confirm whether a path has entered a conductive part of the tire without removing excess material that would result in, for example, wasted material and degraded mechanical properties

A conductive path that is too short to reach the inner circumferential surface of the first layer is detrimental to the tire's ability to function as an antistatic tire because no charge can easily flow through the path

Another consideration with existing methods is that there is no disclosed way of confirming that the pathways after curing are free of defects, such as being completely filled with conductive material, without interruptions of the pathways, eg, caused by non-conductive material or air bubbles that allow passage through the pathways. The flow of charge is impeded
