Abstract

Equipment for making a wire strand is characterised by the following features; an elongate track (12); a clamp (14) at one, leading end of the track rotatable about an axis parallel to the track; an anchor frame (15) at the other trailing end of the track having rotatable tensioning spaced anchorages (16) for wires (17) extending parallel to the track; a trolley (18) movable along the track (12) and carrying adjacent the leading end a rotatable closing die (19) having an aperture (20) of cross-section corresponding to the cross-section of the strand (11), and adjacent the trailing end a grouper plate (21) having spaced wire guide apertures (22) corresponding to the anchorages (16) on the anchor frame (15), there also being on the trolley (18) intermediate the closing die (19) and the grouper plate (21) a lay plate (23) having wire guide apertures (24) with spacings intermediate the spacing of the guide apertures (22) in the grouper plate ( 21) and the closeness in the closing die (19); a first drive arrangement (25) for moving the trolley (18) along the track (12) from the leading end to the trailing end; a second drive arrangement (26) for rotating the clamp (14) at the leading end of the track (12) with a predetermined relationship to movement of the trolley (18); removable supports (27) for the wires (17) at intervals between the trolley (18) and the anchor frame (15); and removable supports (28) for the strand (11) at intervals between the rotatable clamp (14) and the trolley (18).
