BOBBIN AND BOBBINLESS TRANSPORTING METHOD

WIPO Patent Application WO/2016/136570

A1

The purpose of the invention is to allow a filament to be smoothly removed from a bobbin. A bobbin (1) comprises a guiding tube (30), a pair of flanges (10, 20) provided on the ends of the tube, and a winding drum (40) sandwiched between the flanges (10, 20) and provided on the outer circumference of the guiding tube (30). The flange (10) is freely attached to and detached from one end of the guiding tube (30), and the other flange (20) is fixed to the other end of the guiding tube (30). The winding drum (40) comprises a plurality of divided shell plates (41) that are divided by way of a plurality of slits that extend in the direction that the pair of flanges (10, 20) is joined. A biasing mechanism (50) that biases the divided shell plates (41) toward the interior is provided between the divided shell plates (41) and the guiding tube (30). When the freely attachable and detachable flange (10) is mounted, the divided shell plates (41) are supported at the ends of the plate from the inside by supporting projections (15) on the inner face of the flanges (10, 20). When the freely attachable and detachable flange (10) is removed, the divided shell plates (41) move inward.
