PROBLEM TO BE SOLVED: To provide a grafting device and a method of grafting capable of making it more unlikely for a rootstock and a scion to be displaced when tapes are bonded compared with a conventional configuration.SOLUTION: Bonding machines 41 are disposed on both sides of a rootstock 2 and a scion 3 placing them in-between with respect to the longitudinal direction of tapes and bond the tapes 6 and 7 together with bonding parts 42a protruding inward in the tape facing direction. Therefore, compared to a conventional configuration in which each side of the rootstock and the scion is separately bonded, it is possible to make the rootstock 2 and the scion 3 more likely to be displaced when bonding the tapes.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2020,JPO&INPIT【課題】従来の構成に比べて、テープを接着する場合に台木と穂木とをずれにくくする接ぎ木装置および接ぎ木方法を提供する。【解決手段】接着機41が、テープ長手方向に対して台木2および穂木3を挟んで両側に配置され且つテープ対向方向の内側に突出する接着部42aで、テープ6,7どうしを接着することで、台木と穂木の片側ずつ接着していく従来の構成に比べて、テープを接着する場合に台木2と穂木3とをずれにくくすることができる。【選択図】図5
