Product Details

1) PT-Tracking Roller Assemblies:
PT-Tracking roller assembly (TRA) consists of two rectangular steel tubing frames. One is stationery, the other is movable; it is supported in a nylaguide sliding block and arcuate bar system, and has an 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-lubricating. The unit therefore requires no maintenance.

The Principle:
The TRA is designed so that it 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. Because the TRA correction range is increased by lengthening the span. Therefore the correction angle can be kept small to reduce induced stresses to the level desired. Because stresses can be kept minimal, the TRA can be used to guide within the tension loop on your process. It can be installed successfully on lines handling fragile materials such as parchment paper, thin metal foil, or saturated paper even when other guiding methods have failed. It can also be used to make economically large corrections in the web path, even displacing the shifting unwind, because of its very low inserted sness level.

Description :
Standard adapter bases consist of a stationary floor-mounted frame or plate, a four unit, standard nylaguide bearing and support system, and a moving frame or 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.

Applications:
The PT adapter base is designed for use in applications where the unwind or rewind stand must be shiftable. By fitting the adapter base under the stand, a simple and economical installation is obtained. Because of the relatively high mass of the unwind or rewind rolls, its use is most often found in applications. Where response time can be relatively slow and where accuracies are not overly critical.

In rewind guide, the detector is attached to the moving frame before fixed idler with sufficient warp to stabilize web.

In unwind guide, the idler roller attached on moving frame before the fixed detector to stabilize the web.
