1303106 Stranding machines, flyer twisting devices NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP and YOSHIDA ENG CO Ltd 23 Jan 1970 3456/70 Headings DID and D1T A plurality of wires are withdrawn from a canister P or bobbin B supported on a tray 42, pass over a guide roller R 1 above the supply source, and travel downward, guided by roller R 2 , onto a flyer 8 rotated about the tray by belt-driven wheel 5, and are withdrawn along the rotational axis of the flyer. The wire is thus twisted once at roller R, and again between rollers R 3 and R 4 on each revolution of the flyer. Where several wires are stranded together, being withdrawn from coaxially arranged canisters (Fig. 1) or bobbins (Fig. 6), they pass first through a die 11a which, together with the roller R 1 , is rotated by links 12, 12' attached to the flyer, one of which links may carry guide rings 12a, 12b for the wire. The tray 42 is maintained still, or rotated to provide additional twisting, by planet gears 7a, 7b mounted on a shaft in wheel 5 and engaging sun gears 21, 41 the former of which is fixed (Figs. 1 and 6), or by a corresponding belt or chain drive. Instead of using links 12, 12', the die 11a and roller R 1 may be independently driven, in which case a ring may be provided around the wire path (Fig. 7) to prevent ballooning. Several of these apparatuses may be arranged in rows to supply twisted single wires, pairs, triples or quads to another stranding machine for further twisting together (Fig. 2, not shown).
