Joining apparatus and joining method for a cord ply for a tire

A joining apparatus for a cord ply for a tire, comprising:

• a first pressurizer in which a first press, provided in an upper side, faces a first pressure receiver, provided in a lower side;
• a second pressurizer in which a second press, provided in the upper side, faces a second pressure receiver, provided in the lower side, wherein the first pressurizer and the second pressurizer are arranged to face each other;
• and
• engagement claws that can engage with each other and are provided so as to face each other, provided on the first press and the first pressure receiver and on the second press and the second pressure receiver;
• wherein:
• the first press comprises a cord end press capable of vertically moving in a direction perpendicular to a placement surface of a first cord ply,
• a first cord ply positioner that positions the first cord ply by bringing a tail end of the first cord ply into contact with a side surface of the second pressure receiver raised to a position higher than a conveying position of the first cord ply is provided,
• a first cord ply fixator that lowers the cord end press so that a bottom surface of the cord end press presses and fixes the positioned first cord ply against an upper surface of the first pressure receiver is provided, and
• a second cord ply positioner that positions a second cord ply by bringing a tip of the second cord ply into contact with a side surface of the cord end press pressing the first cord ply is provided,
• the first pressurizer is configured so that, the first press lowers to apply a pressing force to the tail end of the first cord ply placed on the upper surface of the first pressure receiver while the bottom surface of the cord end press presses the first cord ply,
• the second pressurizer is configured so that the second press lowers to apply a pressing force to the tip of the second cord ply placed on an upper surface of the second pressure receiver, and
• the first pressurizer and the second pressurizer are brought close to each other in a flow direction of the cord ply in a state where the u pressing force to the tail end of the first cord ply and the pressing force to the tip of the second cord ply are respectively applied by the first pressurizer and the second pressurizer, whereupon a shearing force is applied to an overlapped portion of the tail end of the first cord ply and the tip of the second cord ply.
