Provided are: a fiber-bundle-body bundling method and bundling device whereby the amount of lengthwise space needed to cut an aggregated fiber bundle is reduced while still reliably cutting the aggregated fiber bundle into cut fiber bundles and a hollow-fiber-bundle manufacturing method and manufacturing device. In this fiber-bundle-body (Bd) bundling method and bundling device (100), in which an aggregated fiber bundle (Bb) consisting of an aggregated plurality of continuous fibers (Ba) is sequentially cut into cut fiber bundles (Bc) while being conveyed in the lengthwise direction (W) thereof and said cut fiber bundles (Bc) are sequentially collected and bundled into a fiber-bundle body (Bd), the aggregated fiber bundle (Bb), which is held at a first holding position (P1) and moves in a first direction (X1): is held at a second holding position (P2) after the first holding position (P1) has moved away from a holding/action position (R1) for the second holding position (P2) is held at a third holding position (P3) upstream of the second holding position (P2) and is then cut between the second holding position (P2) and the third holding position (P3). This series of actions is then repeated, with the third holding position (P3) becoming the first holding position (P1).La présente invention concerne : un procédé de liage et un dispositif de liage de corps de faisceau de fibres dans lesquels la quantité despace longitudinal nécessaire pour couper un faisceau de fibres agrégées est réduite tout en coupant encore de façon fiable le faisceau de fibres agrégées en faisceaux de fibres coupés et un procédé de fabrication et un dispositif de fabrication de faisceau de fibres creuses. Dans ces procédé de liage et dispositif de liage (100) de corps de faisceau de fibres (Bd), dans lesquels un faisceau de fibres agrégées (Bb) constitué dune pluralité de fibres continues agrégées (Ba) est séquentiellement coupé en faisceaux de fibres coupés (Bc) tout en étant transporté dans sa
