Abstract:
Apparatus for manufacturing communication cables, comprising at least one ""inside-out"" rigid twist machine; support means for rotatably supporting at least one bobbin wound with a total of at least two insulated conductor wires, within each of said at least one twisting machine to substantially fix the positions and orientations of said at least one bobbin, each of said rigid twisting machines including first drive means for spinning each of said at least one bobbin about their respective axes; fly-off means for flying off said at least two insulated conductor wires wound on said at least one bobbin with substantially no tension in the wires when said at least one bobbin attains a first rotational speed; guide means for guiding the wires from said at least one said bobbin to a closing point; closing means for closing the wires; twisting means including second drive means for twisting the closed wires at a second rotational speed to form a twinned cable; control means for adjusting said first and second rotational speeds and for imparting a twist rate to said conductor wires which is a function of the composite of said first and second rotational speeds; and take-up means for taking up the twinned cable.
