Bottle sealing apparatus

A die truck assembly comprising:

• an actuator guide block;
• a die holder coupled with the actuator guide block by an actuator spring and being movable relative to the actuator guide block between a rest position and a compressed position, the actuator spring being compressed in the compressed position to bias the die holder toward the rest position, the die holder including a die stem having a die support portion and a spring seat, the die holder including an actuator guide tube, the actuator spring being coupled between the actuator guide tube and the actuator guide block, the spring seat being generally fixed on the actuator guide tube, the die stem being slidable relative to the actuator guide tube;
• a centering member coupled with the spring seat by an engagement spring and being movable relative to the spring seat between a rest position and a compressed position, the engagement spring being compressed in the compressed position to bias the centering member toward the rest position;
• and
• a wheel coupled with the actuator guide tube.

• and
• a die supported by the die support portion at the end of the die stem, the die including a die surface with a die image,
• wherein the centering member includes an inner wall which is disposed around the die, the die being recessed from an edge of the inner wall in the rest position of the engagement spring to form a cavity with the inner wall, the die protruding from the edge of the inner wall in the compressed position of the engagement spring.

A die truck assembly comprising:

• a die holder including a die stem having a die support portion and a spring seat, the die holder including a blocking member which is generally fixed on the die stem, the blocking member being coupled with the spring seat by a die stem spring and being movable relative to the spring seat between a rest position and a compressed position, the die stem spring being compressed in the compressed position to bias the blocking member toward the rest position;
• a die supported by the die support portion, the die including a die surface with a die image, the die support portion supporting the die at an end of the die stem;
• and
• a centering member coupled with the spring seat by an engagement spring and being movable relative to the spring seat between a rest position and a compressed position, the engagement spring being compressed in the compressed position to bias the centering member toward the rest position,
• wherein the centering member includes an inner wall which is disposed around the die, the die being recessed from the edge of the inner wall in the rest position of the engagement spring to form a cavity with the inner wall, the die protruding from the edge of the inner wall in the compressed position of the engagement spring.
