ABSTRACT:
A collapsible reel (31) composed of two identical reel halves (1, 1') each comprising a flat annular flange (3, 3') having a central opening (5, 5') and a number of annular segments (7, 7') which are bounded by loop-shaped incisions (9, 9') and which are joined to the flange (3, 3') by a folding rib. Each segment (7, 7') is subdivided by a hinge rib into a securing vane (15, 15') and a bridge part (17, 17'). By means of the securing vanes (15, 15'), the two flanges (3, 3') are joined. The folding ribs (11, 11') and the hinge ribs (13, 13') are arranged so that the reel (31) can be extended merely by a relative rotational movement of the two flanges (3, 3').
