  "abstract": "A cover tape feed device is provided to feed a cover tape onto the surface of a bead core. The cover tape feed device includes a conveyance member that is capable of reciprocating between an advanced position and a retracted position. The conveyance member moves from the retracted position to the advanced position while supporting the cover tape and conveys the cover tape onto the surface of the bead core. The cover tape feed device includes a guide roller for guiding a feed of the cover tape, which is arranged to be rotational at a position farther from the bead core than the conveyance member is from the bead core, and a transmission mechanism that converts movement from the retracted position to the advanced position of the conveyance member into rotation in a tape feeding direction of the guide roller.",
  "claims": [
    "1. A cover tape feed device for feeding a cover tape onto a surface of a bead core, the cover tape feed device comprising: a conveyance member that is capable of reciprocating between an advanced position and a retracted position, wherein the conveyance member moves from the retracted position to the advanced position while supporting the cover tape and conveys the cover tape onto the surface of the bead core; a guide roller for guiding a feed of the cover tape, wherein the guide roller is arranged to be rotational at a position farther from the bead core than the conveyance member is from the bead core; a transmission mechanism that converts movement from the retracted position to the advanced position of the conveyance member into rotation in a tape feeding direction of the guide roller; and a cutting mechanism that cuts the cover tape, wherein the cutting mechanism includes a cutting blade that is capable of moving to cut the cover tape, a direction that is directed to the advanced position from the retracted position is an advancing direction, the conveyance member includes a leading end in the advancing direction, when the conveyance member is located at the advanced position, the leading end of the conveyance member is located on a leading side of a cutting edge of the cutting blade in the advancing direction, and when the conveyance member is located at the retracted position, the leading end of the conveyance member is located on a trailing side of the cutting edge of the cutting blade in the advancing direction.",
    "2. The cover tape feed device according to claim 1, comprising a driving member for moving the conveyance member.",
    "3. The cover tape feed device according to claim 2, wherein the transmission mechanism is arranged between the driving member and the guide roller.",
    "4. The cover tape feed device according to claim 3, wherein the transmission mechanism includes: a rack, which is moved together with the conveyance member by the driving member; and a pinion, which is coupled to the guide roller and engages with the rack to be rotated as the conveyance member is moved.",
    "5. The cover tape feed device according to claim 4, further comprising a one-way clutch arranged between the pinion and the guide roller, wherein the one-way clutch only transmits, to the guide roller, rotation in one direction of the pinion caused by movement from the retracted position to the advanced position of the conveyance member."

  "description_excerpt": "The present invention relates to a cover tape feed device for feeding a cover tape onto the surface of a bead core, which is used for a tire. The cover tape is adhered to the bead core to cover the surface.\n\nThis type of device feeds, to a bead core, a cover tape that is to be wound around the surface of the bead core in order to prevent disorder of a wire included in the bead core and to improve tackiness (adhesiveness) between the bead core and the tire ply.\n\nIn a conventional configuration, a cover tape delivered from a feeding source is longitudinally elongated by being pulled when an edge of the cover tape that is wound around a bead core is fed onto the bead core. This causes a problem of a decrease in the width of the cover tape so that the cover tape cannot ensure a necessary width for covering the surface of the bead core.\n\nAccordingly, it is an object of the present invention to provide a cover tape feed device that limits the decrease in the width of a cover tape, which is caused by the longitudinal elongation of the cover tape when being fed onto a bead core.\n\nTo achieve the above object, a cover tape feed device serves to feed a cover tape onto the surface of a bead core. The cover tape feed device is characterized by including a conveyance member that is capable of reciprocating between an advanced position and a retracted position, a guide roller for guiding a feed of the cover tape, and a transmission mechanism that converts movement from the retracted position to the advanced position of the conveyance member into rotation in a tape feeding direction of the guide roller.",
