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.

Abstract: The bead ring winder winds a cord around the circumference of a former by rotating a rotation shaft to form a bead ring. The former includes a fixed segment, which is fixed to the rotation shaft, and a separated segment, which is coupled to the fixed segment to be movable toward and away from the fixed segment, so that the former is configured to be able to increase and decrease the circumference length of the former. The bead ring winder includes a setting member, which can be replaced to set a separated distance of the separated segment from the fixed segment when changing the winding diameter of a bead ring to be formed, and a fastening plate and a fastening bolt, which fasten the separated segment to the fixed segment.

Abstract: A cover tape feed device (19) is provided to feed a cover tape (12) onto the surface of a bead core (11). The cover tape feed device (19) includes a conveyance member (21) that is capable of reciprocating between an advanced position and a retracted position. The conveyance member (21) moves from the retracted position to the advanced position while supporting the cover tape (12) and conveys the cover tape (12) onto the surface of the bead core (11). The cover tape feed device (19) includes a guide roller (24) for guiding a feed of the cover tape (12), which is arranged to be rotational at a position farther from the bead core (11) than the conveyance member (21) is from the bead core (11), and a transmission mechanism (25) that converts movement from the retracted position to the advanced position of the conveyance member (21) into rotation in a tape feeding direction of the guide roller (24).

Abstract: The present invention relates to a method of inserting an implant in a bone. In the bone, a thin slit is formed by a cutting tool in a mesiodistal direction around an insertion spot of the implant. The thin slit is cut and widened by a bone chisel. Into the implant insertion spot, a tool for forming cavity provided with a needle portion is squeezed while being rotated, and a cavity is formed. In the formed cavity and the slit, blood of a patient is collected, by which a tissue is rapidly regenerated and bonded to the inserted implant, and the implant is firmly fixed to the bone.

Abstract: When a pen holder of a drawing head of an automatic lead supply apparatus is raised and lowered, and a knocking pipe of a pencil holder held by the pen holder strikes or is pressed against a knocking plate in order to repeatedly raise and lower the knocking pipe, a lead contained in the pencil holder is fed to a front end of the pencil holder. Before the lead feeding operation, a controller functions to finely oscillate the drawing head in order to prevent the lead from clogging the knocking pipe. As a result, a single lead will be properly and reliably guided to a lead chucking mechanism.
