Intermediate guiding system
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.
Tracking roller assembly (TRA) consists of two rectangular
steel tubing frames. One is stationery, the other is movable;
it is supported in a BEARING Guide
improper mounting of the detector and improper arrangement of
the rolls will result in unsatisfactory control performance,
or will cause wrinkles to the web.
planning and aligning the process line, the following
described items must kept in mind. If distance is too short,
winkles will happened on thin or soft web.
When needed to correct web position in the middle of the
process line, there are two methods to modify the web edge.
Pivot Roll Guiding:
This method best applied to the webs of novelistic materials,
or distortions web due to the difference tension of both
side. The web hardly slips on this guide roll, since there
has two 90-wrapped angle. If it is slips, use a rubber coated
roll will prevent slip age occurs.
This method particularly good for flexible web. It is
available, when location in long distance between entry idler
roll and exit idler roll. The assumed pivot of the guide roll
rotation be arranged to be long, so turning angle of the
guider rolls and the tension variation are lesser, will
reducing the wrapping of the web. There have 90- wrap for
single roll and 180- wrap for double rolls shown as below.
Whenever the film roll is not feeding in order, it could be
adjusted by EPC control unit and the film feeding will be
corrected to the right position. This system will enhance the
productivity of machine and there will provide one set of EPC
for each line.
are involved in providing a comprehensive range of TRA
rollers. These rollers are use in paper industries. We made
these product as per the client requirement.
manufacture and supply a robust range of SRA Frames. These
have been made using high grade material, which makes them
perfect to be used in a number of applications across the
industries. The frames are available in varied designs and
specifications to meet the diverse requirements of the
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.
specialize in manufacturing quality TRA Frames that meets the
variegated requirements of our client-le. These are available
in various sizes and are customized according to the client-s
specific requirements. Appreciated for the features like
corrosion resistance, durability, high performance and sturdy
construction, these are highly demanded among our customers.
Moreover, we offer them at cost effective prices.
Positive Displacement / Steering Roll assemblies consist of a
stationery base & movable frame with idler rollers. Two pair
of CON-PAP-TEX Nylaguide bearings support the moving frame.
Positive displacement guides are suitable where long entry
span is not available like on printing m/cs. Steering roll
guides are available in single or double roller assembly and
are idle for machines where, long free entry span is
available. Edge Position Control, Center Pivot Roll Guiding, End Pivot Roll Guiding, Edge Position Control, Four TRA Rollers, SRA Frame, Intermediate Guide All these guides are designed for minimum web stress & can be installed horizontally, vertically or up-side
down. Tension Control Unit works in process with arcuate bar program, and has ab idler curler at either end.
