A manufacturing method of an insulation cap, includes the steps of: supplying an elongated tube from a tube supplying unit to a tube placing table; moving a tube press-fastening portion and a welding body portion towards the tube placing table so as to press-fasten a press-fastening position of the tube placed on the tube placing table and to press-contact a press-contacting position of the tube placed on the tube placing table; performing a welding process with respect to the press-contacting position of the tube; moving the tube placing table during the welding process to feed the tube in a tube feeding direction by a specified amount; blanking the tube subjected to the welding process after feeding the tube to form the insulation cap; and discharging the formed insulation cap from a blanking position.

Manufacturing method and manufacturing apparatus of insulation cap

A forming apparatus for forming a wire joint portion including a connection portion and an insulative tube covering the connection portion is provided. The forming apparatus includes: a production information acquiring unit which acquires production information; a connection portion forming unit which fixes a plurality of wires selected on the basis of the production information, and then electrically connects conductor portions of the wires together to form the connection portion; a first fusing unit which fuses one open end portion of the insulative tube to close the one open end portion; an inserting unit which moves the wires so as to insert the connection portion into the insulative tube through the other open end portion of the insulative tube; a second fusing unit which fuses the other open end portion of the insulative tube and insulative sheaths of the wires together so as to form the wire joint portion.

Forming apparatus and forming method of wire joint portion

A cap that covers an electric wire connecting portion in which respective conductive portions of a plurality of electric wires are interconnected is molded in such a manner that one end side of a tube having a tubular shape is hermetically sealed by welding treatment, and a tongue portion is formed by a stamping process on the other end side.
