in tension which the controller corrects. The greater the
sensitivity of the load cell used, the more precise it is at
detecting even the slightest changes in the tension of the
material.
Tension controllers
Tension controllers are the brains of the operation
(Fig.16). Process parameters are entered into the controller and then, depending on the type of controller, it will
utilize load cells, dancer position feedback, or diameter
calculations to control the torque of a brake, clutch or drive
to maintain a set tension. High-quality tension controllers
also come with a variety of additional functions such as
soft start, anti-coast, web break detection, splice, taper and
more. Depending on the process, these functions increase
process capabilities to ensure maximum productivity.
Tension brakes
Brakes are often either pneumatic or electrical and apply
torque to the roll of material to properly apply tension
to the web (Fig.17). In pneumatic brakes, friction pads
engage with the brake disc in what is referred to as continuous slip to control the amount of torque being applied to
the brake. In electrical brakes, or magnetic particle brakes,
electrical current is used to produce the amount of torque
output of the brake.

Modular automated tensioners

* High-tech functional
coatings

One of the latest innovations for composites manufacturing has been the modification of Montalvo's nip technology
to create what is referred to as modular automated tensioners (Fig.18). Modular automated tensioners easily integrate
into existing machines to create a single location for producing precise tension control for multiple-creel applications. These devices are fully customizable and so can be
longer or shorter, or multiple units stacked on top of each
other. For example, in one application such devices are
controlling over 250 individual tows of material. Modular
automated tensioners ensure the material is at precise and
consistent tension as it enters processing, or before the
material gets its resin bath to ensure uniform coating. n
