High-speed taping payoff
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" (76mm) 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.
