Device for Inserting a Wire Into a Tire

A device for inserting a wire into a tire, comprising:

• a frame;
• a feeding means mounted to the frame for feeding a wire;
• a movable support movably mounted to the frame;
• and
• a needle mounted to the movable support, the needle comprising
• an elongated shaft having:
• a cylindrical part having a proximal end and a distal end;
• a piercing zone at the distal end of the cylindrical part, the piercing zone having a bisecting plane of reflection-type symmetry, the piercing zone having a diameter that reduces toward a distal end of the shaft in a conical shape;
• a shaft axis;
• and
• a single duct extending lengthwise through the entire cylindrical part from a proximal opening in the proximal end of the cylindrical part through the cylindrical part into the piercing zone to a single distal opening in a part of the piercing zone removed from a distal end of the piercing zone, the single duct being off center relative to the shaft axis at the single distal opening, the single duct being rectilinear,
• wherein the needle is positioned on the movable support so that wire fed from the feeding means enters the elongated shaft, and
• wherein the movable support is movable between a low position in which the piercing zone of the needle is positioned to pierce a surface of a tire, and a raised position in which the piercing zone of the needle is not in contact with the surface of the tire.
