FEATURES |
| |
|
 |
Modular Design, allows the controller to be
configured to exact application. |
| |
|
|
All customer adjustments are on board to simplify
set-up. |
| |
|
|
Microprocessor based control, can be used in any
tension zone ( Unwinder , Re-winder &
Intermediate). |
| |
|
|
To enter data using keypad allows the user to scroll
through the selections and values,
making set-up easy. |
| |
|
|
Indication and correction will be reliable
and efficient. |
| |
|
|
Close loop control by measuring web tension by
two load cells, insures that malfunctions or wrong
web tensions are corrected. |
|
|
|
| |
|
|
| |
In Modern Production plants,
processes are to
large extend automated with manual interventions
being reduced as far as possible. Hence automatic
web tension controlling is essential if expectations in this
respect are to be satisfied. |
|
| |
|
|
| |
ATC 2000 Series controls Unwind, Rewind and
Intermediate web tension automatically. |
|
| |
|
|
| |
Just set the desire tension and the controller
maintain it by automatically compensating for various
roll diameter, speed, web material etc. Actual tension
and set tension is displayed on digital meter. Standard
features include auto/manual, tension on/off, manual
setting pot, Soft start and mains on/off. Available with
enclosure. Outputs available to control motor drive,
powder brakes, pneumatic brakes etc. |
|
| |
|
|
| |
|
|
| |
| |
Alteem tension transducers (Load cells) measure
actual web tension of any moving web with an output
which is accurate, reliable and could be used in any
indicator or controller. ALTEEM tension transducer has
rugged stainless steel and aluminum housing to give
you dependable performance and long life. The type of
construction provides easy mounting on machines for
most applications. The push/ball bearing mounting
provided on the load cells make it simpler to fix the
rotating or stationary idle rollers. |

Briefly, the coupling comprises of two
concentric parts, the body or input part containing the
field coil within it, separated by small annular gap, an
inner rotor, or out put part. The annular gap contains a
ferromagnetic powder, which is activated when the coil
is energized. The resultant flux which is generated,
passes through the powder, causing it to align with the
flux path, and thereby creates a driving bond between
input and output part, the strength of which is solely
determined by value of D.C. current applied to the field
coil.

Pneumatic brakes of various sizes and types are
available to fit any applications. They are simple to use,
easy to replace worn out brake pads.
Brakes come fully assembled, ready to fit and
easy mounting. These brakes are mainly used as
Actuators for Un-winder applications.
