Method and device for repairing tubeless tubular tires for bicycles

A method for repairing a puncture hole in a tubeless tubular tire and a tubeless cover, said method comprising:

• providing an elongate hollow injection needle having a first end connectable to a source of cement and a second end adapted to be inserted through saisd puncture hole in said tire, said needle having extending therethrough, throughout the entire length thereof from said first end thereof to said second end thereof, an internal hollow passageway through which cement from the source may be supplied, said needle having at a position intermediate said first and second ends thereof at least one lateral orifice extending through said needle from said internal passageway thereof to the outer surface thereof, and said needle having an end orifice extending through said needle from said internal passageway thereof to the extremity of said second end thereof;
• connecting a source of cement to said first end of said needle;
• inserting said needle through said puncture hole in said tire to a position such that said lateral orifice is inwardly spaced from the inner surface of said tire;
• inclining said needle with respect to a radial line through said puncture hole, thereby bringing said lateral orifice to a position adjacent said inner surface of said tire;
• manipulating said source of cement and thereby forcing said cement through said internal passageway and outwardly through said lateral orifice onto said inner surface of said tire, while rotating said needle about the axis of said puncture hole, and thereby depositing on said inner surface of said tire a first quantity of cement in the form of an annular patch surrounding said puncture hole;
• partially withdrawing said needle from said puncture hole to a position whereat said lateral orifice is within said puncture hole and is blocked and sealed by the puncture edges of said tire;
• manipulating said source of cement and thereby forcing said cement through said internal passageway and outwardly through said end orifice, thereby forming on said second end of said needle a second quantity of cement in the form of a drop at a position aligned substantially centrally of said puncture hole;
• and
• completely withdrawing said needle from said puncture hole, and thereby depositing said drop of cement centrally of said puncture hole and causing said drop to join with the center of said annular patch of cement, to thus form on said inner surface of said tire a relatively wide deposit of cement centered on and sealing said puncture hole.
