Twister, method for producing twisted wire, ply, and pneumatic tire

A twister comprising:

• a rotating body that twists a plurality of wire materials fed thereto to form a twisted wire;
• and
• a discharging device that discharges the twisted wire from the rotating body,
• wherein the end portion of the discharged twisted wire is void of a winding apparatus, and is free to rotate with a rotation of the rotating body.

A twister comprising:

• a rotating body that twists a plurality of wire materials fed thereto to form a twisted wire;
• and
• a discharging device that discharges the twisted wire from the rotating body,
• wherein the twisted wire downstream of a twisting point is provided directly to a machine for processing without being wound on a bobbin.

A method of forming a twisted wire using a twister comprising:

• feeding a plurality of wires to a rotating body of the twister;
• rotating the rotating body to twist the plurality of wires to form the twisted wire;
• discharging the twisted wire from the rotating body;
• and
• satisfying at least one of the following conditions:
• a) avoiding a winding structure at an end portion of the twisted wire downstream of a twisting point during an entire time that any portion of the twisted wire is within the rotating body, and
• b) avoiding a winding structure at an end portion of each of the plurality of wire materials upstream of a twisting point during an entire time that any portion of the plurality of wire materials is within the rotating body,
• whereby at least one of the end portions is free to rotate with the rotating body.
