Process for the manufacture of a plurality of bundles of semipermeable hollow fibres for a membrane apparatus from a sheet of fibres (19) which is formed by winding a fibre or a strand of fibres (11) onto a drum (1, 2), consists in: … … - cutting the sheet of fibres (19) on the drum (1, 2) along a cutting line which is substantially parallel to the axis of the drum (1, 2); … - stretching out the sheet of fibres (19) on a flat surface (14); … - winding the sheet of fibres (19) onto itself in a direction perpendicular to the cutting line to form a single bundle of fibres (45); … - sectioning the single bundle of fibres (45) into a plurality of bundles for a membrane apparatus. … …<IMAGE>… |
