After adding all the new sheathing materials and applying them in a longitudinal direction on the new tandemized extrusion line for alpeth cable, some very interesting results were observed. All the above additions were made to the former extrusion line without increasing the number of operators required by simplification of the material splicing and transfer operations and the better utilization of the operators time. In addition, the following economics were derived 1 Elimination of separate operation of spiral wrapping on a drum type strander by application of all sheathing materials longitudinally in a tandemized extruder line. 2 Elimination of a nylon binding over the plastic type by use of special holddown tooling. 3 Reduction in the number of core trucks required and floor space by combining all sheathing operations in one assembly line. 4 Reduction in production time interval and investment. 5 Reduction in scrap material due to improved designs of tools. 6 Reduction in final sheathing diameter by changes to thickness of materials and method of application.
