Claims20
A winding wheel equipped with a plurality of devices for wrapping a bundle of hollow fiber membranes, wherein each of the plurality of devices comprises:
- a base featuring a trough in the shape of a cylinder section;
- and
- on each longitudinal side of the trough, a rigid flap with an inner surface forming a cylinder section, each of the two flaps being connected to the base via a hinge, the hinges being located on the longitudinal brims of the trough, so that each of the two flaps is moveable between a first position and a second position,
- wherein each of the plurality of devices comprises a sheet of wrapping material and is configured to receive the sheet of wrapping material and a plurality of fibers when both flaps are in the first position, and the trough and the two flaps together frame a cylindrical void when both flaps are in the second position.
