It consists of two rectangular steel tubing frames. One is stationary, the other is movable. it is supported in a nyalguide sliding block and arcuate bar system, and has ab idler roller at either end.
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. The unit therefore requires no maintenance.

- Path rollers are normally aluminum, statically or dynamically balanced.
- Air for flotation requires 5 CFM per 100mm web width at 10ins to 18ins W.G. depending on web tensions.
- Fans direct mounted on each Turner Bar can be supplied at the time of manufacture (option). For narrow web widths and special applications air flotation holes can be reduced for using compressed air or arranged as required.
