A kit of parts for assembling an elongate former suitable for transversely folding a longitudinally advancing tape around an advancing cable core comprises a primary former having a conically-shaped channel therethrough, a plurality of separately formed nose cones each having a conically-shaped bore, the cross-sectional size of the bore of each nose cone at its downstream end differing from that of each of the other nose cones, and means for detachably securing any nose cone to the downstream end of the primary former. Each nose cone has a length substantially less than the primary former and, as a consequence, each nose cone is readily formed from a transversely folded strip of sheet metal. |
