| TRV Soft Rubber
Roller Series
The following four kinds rubber roller belong to soft rubber
roller series, whose common characteristic are:
high abrasive resistance, high elasticity, low deformation,
free treatment, high stability of physical and mechanical
property.

1) High abrasive resistance:
With the special macromolecule, reasonable and scientific
formulate, soft rubber roller are of high abrasive resistance.
During the spinning, the surface roughness of rubber roller
change little to guarantee the stable quality of spinning.
High abrasive resistance is a key factor to guarantee
and lengthen the life of rubber roller, which reduce the
cost of production and spinning. |

2) High elasticity, low deformation:
Soft rubber roller are produced by choosing some patent
manterials, which make the control area on fiber wider,
nicer and more stable. The high elasticity and low deformation
are the remarkable properties of soft rubber roller and
are the reliable guarantee of excellent spinning quality. |

3)Free treatment
The formulate of rubber roller completely follow the theory
of "Charge Difussion", which are helpful to
the exclusive spinning flexibility of rubber roller. Free
treatment simplify the process, reduce the cost and pollution,
improve the production efficiency. |

4) Stable physical and mechanical properties:
Soft rubber roller are of stable physical and mechanical
properties. Their hardness, antioxidation, antipollution
change little during using time, showing a high ratio
between property and price. |

| The
process and maintenance of TRV soft rubber roller series
The rubber roller with aluminum liner:
1) clean the surface of bear, and paste some lube on bear
2) You can use vertical sleeve pressor machine to fix the roller.
You should fix the roller on the special jacket head, then you can
press the roller into the bear. You must keep the concentricity
between roller and bear, the pressure is working on the rubber roller,
this procedure should be even speed and bear should enter aluminum
liner. After fixed, the roll shold be arranged on the wood shelf
for polish.
Double layers rubber roller:
1) clean the surface of bear, and paste some adhesive on one third
of bear
2) Put thr roller into the bear by cone guide cap, before the drying
of adhesive, you should press the roller in seconed time to clear
the stress caused by roller press. After fixed, the roll shold be
arranged on the wood shelf for polish. Before the polish, the roller
should be dried for 2-3 days.
The polish of rubber roller:
1) Grind the roller in normal A800 rubber grinder with 50-60 holes
grinding wheel
2) Grind the roller untill the dia is 30.10-30.05mm, stop the grind
and lay for 1 day
3) grind the roller again with 60 holes grinding wheel till the
dia is 30mm, then polishing for 2-4 times. After polishing, park
the roller in the workshop, one day later, you can used it on machine
Suggestion: For 2055-2068 soft rubber roller: the best termperature
is about 25 , humidity is 50-60%; The recycling
period of 2060 and 2055 soft rubber rolleris 6 months, The recycling
period of 2065 & 2068soft rubber roller is 6-9 months
When the roller is used in the machine, after a certain
time, you need recycling-grind the roller:
1) unload the roller from the loom, pack it on the shelf
2) Grind the roller in normal A800 rubber grinder with 50-60 holes
grinding wheel
3) Grind the roller untill the dia is 29.80-29.755mm, stop the grind
and lay for 1 day
4) grind the roller again with 60 holes grinding wheel till the
dia is 29.70mm, then polishing for 2-4 times. After polishing, park
the roller in the workshop, one day later, you can used it on machine
5) In each recycling-grind, you must grind the roller and remove
the surface for 0.30mm, then the roller can work properly.
Suggestion:
After 3 months, you shoud wash the 2060 & 2055 soft rubber roller
with clean water and dry it in room temperature, and then pack it
for one day. For 2065-2068, after 6-8 months, you should clean it
with detergent, the temperature is less than 40, dry it in room
temperature, then pack it for one day.
No pile the roller in any condition |
