Pivot Tracking Assembly
PIVOT TRACKING ASSEMBLY
- The web can be fed over the TRA in A ‘U’ shaped path, reversing its direction of travel, or through the TRA in a ‘Z’ configuration, maintaining the same direction of travel
- It is insensitive to attitude and can even be mounted upside down.
- Solidly supported on all four corners by nylaguide bearings, it is not subject to deflections caused by cantilever stresses.
- Radial bearings are sealed, and linear bearings are self – cleaning and self – lubrication.
- Standard adapter bases consists of a stationary floor mounted frame or plate, a four unit, standard nylaguide bearing and support system, and a moving frame of plate.
- A heavy duty servo cylinder is nested between the frames and the nylaguide bearings.
- The servo cylinder moves the upper adapter base plate back and forth in response to hydraulic signals from the power unit.
THE PRINCIPLE:
- The TRA is designed so that is swings in an arc laterally, pivoting about an imaginary pivot point located exactly in the plane of the entering web path.
- The servo cylinder swings the other end of the frame, moving the outgoing web laterally back into the desired web path.
- It can be installed successfully on lines handling fragile materials such as parchment paper, thin metal foil, or saturated paper even.
