Patent ID: 8087433

Claim:
An apparatus for forming a cabling media using a wire pair including first and second conductor members, each of the first and second conductor members including a respective conductor and a respective insulation cover surrounding the conductor thereof, the apparatus comprising: a wire pair twisting device adapted to twist the first and second conductor members about one another to form a twisted wire pair; and a wire pair twist modulator upstream of the wire pair twisting device, the wire pair twist modulator including an engagement member to hold the first and second conductor members at a hold location to restrict rotation of the first and second conductor members about one another; wherein the apparatus defines a twist zone extending from the hold location to a twist initiation location of the wire pair twisting device; and wherein the wire pair twist modulator is operable to move the engagement member along a control axis to modulate the length of the twist zone and thereby the twist length of the wire pair to form the twisted wire pair with a twist length that purposefully varies along a length of the twisted wire pair, wherein the apparatus imparts a pretwist to a segment of the wire pair in the twist zone and imparts additional twist to the segment of the wire pair downstream of the twist zone.
