Tracking Rolls Additional (TRA) – Precision Support for Corona Treater Systems
The Tracking Rolls Additional (TRA) by ElectroTech Industries is an advanced component designed to optimize the performance of any corona treater machine. Engineered for precision web alignment and smooth material handling, TRA units play a critical role in enhancing the efficiency of corona treatment systems used across the printing and packaging industries.
As an essential part of modern surface treatment equipment, TRA ensures consistent film tracking, reduced material wastage, and improved treatment uniformity—making it ideal for plastic surface treatment machines and high-speed production lines.
Why Tracking Rolls Additional (TRA) is Important
In industrial corona treater systems, accurate web alignment is crucial for uniform surface treatment. Misalignment can lead to uneven corona discharge, poor adhesion, and production losses.
The TRA system supports:
Stable web positioning during inline corona treatment
Improved treatment consistency across the film width
Reduced edge damage and material wastage
Enhanced efficiency in film surface treatment machines
TRACKING ROLLER 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.
