Claims16
A method of manufacturing a tire casing, comprising the steps of:
- forming turns centered on a main axis (8) of the casing with at least one electrically conductive wire, and
- disposing a bonding layer inside the casing.
A tire casing, comprising;
- at least one wire forming turns centred on a main axis of the casing, and
- a bonding layer comprising a hot-melt material.
A method of retreading a tire casing, comprising the steps of;
- heating a bonding layer by means of a wire through which an electric current passes and wherein the wire extends inside the casing and forms turns centered on a main axis of the casing.
A tread which is in the form of a closed ring and does not have a casing carcass and wherein at least one electrically conductive wire forms turns centered on a main axis of the tread.
