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.

A method of and an apparatus for balancing a multi-bay cabler system when less than all of the cabler frame bays are supplied with a supply bobbin are disclosed. The apparatus comprises a mechanical counterweight system which compensates for a depleting strand supply during operation of the cabler system, thereby equalizing centrifugal loading within the rotating strander frame and maintaining its dynamic balance at full design speed during the cable assembly operation. The counterweight system is installed in a bobbin-carrying cradle of an unused cabler frame bay. According to a first embodiment, the counterweight is driven in a linear path relative to the cradle in a direction normal to the rotational axis of the cabler frame. According to a second embodiment, the counterweight is driven in an arc relative to its supporting cradle. A control system analyzes an out-of-balance condition and effects a repositioning of the counterweight to maintain the rotating cabler frame in dynamic balance as the bobbin supply is payed out from the rotating frame. Alternatively, the control system may include a computer which positions the counterweight based on a control algorithm.

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.

An apparatus and process for manufacturing insulation for metallic rod which includes a mechanism for housing a plurality of ingredients, scales for weighing a predetermined quantity of each ingredient, a blender for blending predetermined amounts of each ingredient into one material, a mixer to mix the dry blend of ingredients, a mill to form the blended material into strips, a dicer to transform the strips into pellets of insulation, an extruder for placing insulation around the metallic rod, a conveyor to transport the ingredients and/or material between each of the above steps, a controller for outputting commands to the blender and receiving inputs from the scales to obtain the predetermined amount of each ingredient, and a computer for verifying that the correct amount of each ingredient has been obtained. The ingredients used in the manufacture of this insulation material include plasticizers, fillers, a resin, and modifiers. In the step of obtaining the correct weight of each ingredient, the controller employs multiple setpoints to gradually obtain the required ingredient weight through what is known as a dribble feed function.
