A mould for use in the manufacture of a reel as described above comprises a main mould part having a generally-cylindrical mould cavity which is open at one end and defines the outer shape of the reel and its end wall, and a second mould part which closes the open end of the cavity and is provided with core elements which extend into the cavity and define the spaces between the radial webs and the bore through the centre of the reel.
