The TailPlus machine is capable of<br />
testing all grades and speeds up to<br />
3,000 m/min. The sheet width varies<br />
from 500 mm to 800 mm. The machine is<br />
located together with the main <strong>Voith</strong> pilot<br />
machine in the Heidenheim Research and<br />
Development centre.<br />
The TailPlus machine contains the following<br />
machine sections; unwind unit, last<br />
dryer cylinder, felt, simulated Janus calender<br />
and a Sirius Reel. These sections<br />
are located on the machine to accommodate<br />
optimization of tail threading in the<br />
dry end (reel threading). The machine is<br />
also used for optimizing threading for<br />
high speeds and demanding sheet runs.<br />

<strong>Voith</strong> Tail Threading pilot machine<br />
<strong>Voith</strong> Tail Threading Group now has a Threading Pilot<br />
Machine, TailPlus, in <strong>Voith</strong>’s Heidenheim (Germany) R&D facility.<br />
The TailPlus Pilot Machine was developed to offer customers complete<br />
threading support including product and applications testing.<br />
The equipment on the pilot machine includes<br />
a wide range of threading optimization<br />
solutions. A WaterJet TailCutter<br />
is installed to cut the tail on the dryer<br />
can.<br />
A VTT Turbo conveyor with a TT3000<br />
transfer device is installed to pick up the<br />
tail from the dryer can. For certain installations,<br />
a Flip Tray transfer device can<br />
also be used. The VTT Turbo conveyor<br />
moves the tail onto another conveyor and<br />
into the rope nip on the Janus Calender.<br />
The tail is transferred through the Janus<br />
Calender and onto the Sirius Reel with a<br />
rope system.<br />
A high speed digital camera system, Web-<br />
Vision, is also installed on the threading<br />
pilot machine. This allows the customers<br />
a slow-motion view of the threading<br />
process.<br />
The purpose of the threading pilot machine<br />
is to create a facility where the customers<br />
can get their specific threading<br />
applications tested, and to provide a full<br />
R&D facility for threading optimization<br />
and product development. Currently,<br />
tests for Leipa Schwedt PM 4 and Maxau<br />
PM 6 are being carried out. The test facility<br />
has proven it’s usefulness as a customer<br />
specific testing site and an R&D<br />
facility.
