Dynamex Corporation is now offering a new version of the high-speed taping payoff with auto-splicing, designed specifically for the European and international markets. It uses Siemens PLC, drives, and other components these markets prefer at full line speed for taping at the extruder, longitudinal auto-splice taping. New version from Dynamex

This small footprint patented (USA, Canada, EU) payoff enables taping continuously in the extrusion line with unattended automatic splices. These tape payoffs are fully driven, and the tape always runs at constant tension, including at the instant of crossover. Low tape tensions are attainable at high line speeds, and tension is readily adjustable. The tape payoff runs and splices automatically at speeds up to 1,500 FPM (460m/min) and can operate with tissue, paper, water-swellable, mylar, PE and aluminised tape. Models are available for tape width up to 3" (76 mm) or wider. The payoff is installed off-line at an angle to the line so it can be easily

added to existing installations. A tape-redirection unit delivers the tape parallel to the core into the tape-former. Optional retractable wheels make it a portable unit. A new version is now offered that can handle both flat pads and traversed pads. These machines are useful for jacketing operations that use longitudinal taping, but they can also be used for other continuous processes. Another type of constant tension payoff is designed to work specifically on Dynamex or other single-twist cabler lines. Offered with this takeup is a “dial-in-angle” tape-redirection unit. This unit delivers the tape to the cable at the correct helical angle without trial-and-error. This payoff has two positions to speed up tape changeover, or to perform an easy manual on-the-fly splicing, and is also suitable for low speed jacketing lines, where non-automatic on-the-fly splices are acceptable. Another model of this payoff is designed for feeding in two tapes simultaneously to the cabler line, when the cable construction requires two tapes with or without a drain wire.

Improving performance Nexans’ newest product, Energex ® Extra, uses Dow Endurance™ HFDC-4202 tree-retardant cross-linked polyethylene (TR-XLPE) insulation. The advantages of Energex Extra using Dow Endurance HFDC-4202 are said to include improved resistance to water tree growth, higher retained dielectric strength after ICEA 360-day accelerated water treeing test (AWTT) and reduced cost of ownership through longer cable life.
