Abstract

A reel includes a pair of segments which are demountable from each other and one of which is moulded integrally with a flange, while the other segment includes a segmental inner member and a segmental outer member which are connected by a pair of connecting members at their ends. The outer member is prevented from deforming polygonally by providing a sectorial space between the inner member and the outer member, with a clearance between the inner member or the outer member and the adjacent rib which extends almost across the sectorial space.
