Patent number: 6530205Abstract: A method of and an apparatus for making twisted electrical cable, such as 600 volt secondary distribution (UD) cable, and the twisted cable product are disclosed. The apparatus comprises a first plurality of stationary payoff reels each wound with a length of stranded bare wire conductor. The stranded conductors are simultaneously payed off the reels to a pay out accumulator for accumulating a portion of the stranded conductors during replacement of spent pay out reels. An extruder apparatus arranged downstream of the accumulator applies a plastic insulation material to a respective stranded conductor as it passes through the extruder. A cooling trough through which water is flowed cools the plastic insulation. A take-up accumulator arranged downstream of the cooling trough accumulates a portion of each insulated conductor during changeover of the take-up arranged downstream of the take-up accumulator.Type: GrantFiled: March 27, 2000Date of Patent: March 11, 2003Assignee: Southwire CompanyInventors: Bobby C. Gentry, Jerry M. Hesterlee, Clinton E. Watkins, James H. Sullivan

The apparatus comprises a first plurality of stationary payoff reels each wound with a length of bare wire conductor. The conductors are simultaneously payed off the reels to a pay out accumulator for accumulating a portion of the conductors during replacement of spent pay out reels. At least one extrusion process arranged downstream of the accumulator applies a plastic insulation material to a respective conductor as it passes through its respective extrusion process. A cooling and/or curing trough through which water is flowed cools and/or cures the plastic insulation. A take-up accumulator arranged downstream of the cooling and/or curing trough accumulates a portion of each insulated conductor during changeover of the take-up reel arranged downstream of the take-up accumulator.Type: GrantFiled: May 2, 2002Date of Patent: March 4, 2003Assignee: Southwire CompanyInventors: Bobby C.

Publication number: 20020174642Abstract: A method of and an apparatus for making twisted electrical cable, such as 600 volt secondary distribution cable, and the twisted cable product are disclosed The apparatus comprises a first plurality of stationary payoff reels each wound with a length of bare wire conductor. The conductors are simultaneously payed off the reels to a payout accumulator for accumulating a portion of the conductors during replacement of spent payout reels. At least one extrusion process arranged downstream of the accumulator applies a plastic insulation material to a respective conductor as it passes through its respective extrusion process. A cooling and/or curing trough through which water is flowed cools and/or cures the plastic insulation.

Patent number: 5540041Abstract: Apparatus for stress relieving multistranded cable includes a rotatable cradle of a double twist strander which carries a plurality of guide sheaves, a dual wheel capstan, and a take-up reel and a pay-off reel arranged to substantially reduce the length of the path of travel of the advancing cable and to impart stress relieving rotation and tension to the advancing cable. After the cable has been payed off of a stationary pay-off reel, it is advanced to a pair of metering sheaves to fix the starting point of the stress relieving process. From the metering sheaves, the cable advances to the dual wheel capstan mounted for rotation with the take-up reel on the cradle of the strander.Type: GrantFiled: September 13, 1994Date of Patent: July 30, 1996Assignee: Southwire CompanyInventors: Steven R. Campbell, Clinton E. Watkins

Patent number: 5301119Abstract: An expert system having a computer which can receive input data and from stored data to produce an optimized die draft schedule for a given wire drawing machine. The system is adaptable to store data for a plurality of die drawing machines, producing an optimized die draft schedule for a range of input and output rod/wire sizes on each drawing machine for which the system has stored operating parameters. Alternatively, operating parameters for additional drawing machines can be entered, enabling generation of optimum die draft schedules for most wire drawing machines. An enhanced mode may be made available to enable comparison of computed values and operator estimated values.Type: GrantFiled: December 23, 1991Date of Patent: April 5, 1994Assignee: Southwire CompanyInventor: Clinton E. Watkins

Patent number: 5213644Abstract: A method of and an apparatus for applying a moisture block compound to a stranded electrical conductor using a double twist buncher apparatus are disclosed. An oil, such as drawing oil, is applied to the outer layer of wires to prevent "rolling" of the moisture block compound to the exterior of the stranded conductor. An improved applicator is also disclosed for applying the moisture block compound to the core of the stranded conductor in a coating having a precisely controlled thickness.Type: GrantFiled: March 20, 1991Date of Patent: May 25, 1993Assignee: Southwire CompanyInventors: Donald R. Phillips, Hai T. Lam, Clinton E. Watkins, Steven R. Campbell
