Etind Electrotech may be a leading manufacturer of tracking Roller Assembly. we offer Associate in Nursing correct trailing Assembly system with net web Guiding system Unit or Edge Guiding Unit Consisting of 2 rectangular steel conduit frames. One is stationary, the opposite is movable. it's supported {in a|during a|in Associate in Nursing exceedingly|in a very} nyalguide slippery block and curved bar system and has an loafer roller at either finish.
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. Also, Tracking Roller Assembly with heavy duty and accurate for different industries and machinery.
The web will be fed over the tracking Roller Assemblies during a ‘U’ formed path, reversing its direction of travel, or through the tracking Roller Assemblies during a ‘Z’ configuration, maintaining an equivalent direction of travel. it's insensitive to angle and might even be mounted the wrong way up. Solidly supported on all four corners by nylaguide bearings, it's not subject to deflections caused by cantilever stresses. Radial bearings ar sealed, and linear bearings ar self–cleaning and self–lubrication. The unit, therefore, needs no maintenance.
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.
