Model PD-3
Payoff Unit for Stem Pack/Formers
Smooth payoff and steady back tension are provided by this system.
The main component of this unit is an inverted cone, which is placed on top of the former and the wire. This cone moves downward as the wire pays off, gently forcing the wire outwards around the contour of the cone and past a smooth ring on top. The wire is then guided through a Wyrepak cap and tension brush (PD-1) affixed to the top of the stem pack/former.
A “snagger” switch can be included as an option to signal the unwinding system
to stop should a tangle or snag occur, although this is not normally necessary.
- The slots positioned in the inverted cone allow the cone to protrude inside the stem pack/former, insuring that a smooth conical surface is presented to the material being paid off at all times.
- The unit can be used on all continuous pull processes, and is considered essential in pull and cut situations.
