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.
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.
