Controlling web tension, and accumulating lengths of web, by actively controlling velocity and acceleration of a festoon
InactiveUS6473669B2The result is accurateMultiple dynamo-motor startersFilament handlingControl systemActive force
This invention pertains to processing continuous webs such as paper, film, composites, and the like, in dynamic continuous processing operations. More particularly, it relates to accumulating limited lengths of such continuous webs and to controlling tension in such continuous webs during the processing operation. Both tension control and limited accumulations are achieved in a festoon system by connecting a corresponding festoon to actuator or the like, sensing variables such as position, tension, velocity, and acceleration parameters related to the web and the festoon, and providing active force commands, in response to the sensed variables, to cause translational movement, generally including a target acceleration, in the upper festoon rolls to control tension disturbances in the web while providing limited accumulation of a length of the web. In some applications of the invention, the festoon control system is used to attenuate tension disturbances. In other applications of the invention, the festoon control system is used to create controlled tension disturbances.

In-line strainer with tension control mechanisms for use on high tensile wire
InactiveUS20120138882A1Reduce manufacturing costLow cost manufacturingRopes and cables for vehicles/pulleyFencingHigh intensityTension control
An in-line strainer for placement within a span of wire fence to apply tension thereto is provided. The in-line strainer includes a reel having a hollow central hub for receiving a torque limiting mechanism. The torque limiting mechanism includes a central axle and a spring mechanism. As the axle is manually rotated, the reel is also rotated through its engagement with the torque limiting mechanism until a target tension on the wire is reached. Once the target tension has been reached, the torque limiting mechanism disengages, allowing the axle to “slip” relative to the reel, preventing further rotation of the reel and, consequently, further tensioning of the wire. In addition, the in-line strainer includes a failure mechanism which ensures that, when the load threshold on the fence is exceeded, the in-line strainer will automatically release tension on the wire wound thereon in a predictable and safe manner.
