This equipment is intended to evaluate the Rub Proofness of prints on paper or board. It can also be used to measure / evaluate Colour Transfer from printed / coated surface during rubbing. The application can be extended for measurement of abrasion resistance of some Plastic materials / Aluminum Foils.
PRINCIPLE :
In this machine, 2 samples of the same substrate are rubbed against each other in the same plane, under a constant pressure of 2 p.s.i and at a fixed speed of 60 RPM. The number of rubs are recorded using a non-contact type digital counter.
INFERENCE :
This machine works as a great comparator of the variations in print quality between various batches or various suppliers Higher Rub Resistance = better print quality. Lower Rub Resistance = poor print quality.
DESIGN SPECIFICS :
- The highest degree of parallelity of disc samples.
- Accurate R.P.M. of rotating disks assured by High torque Step Synchronous motors.
- Very Low power consumption (Less than 100w).
- No Gearbox. Hence, No Maintenance.
- Compact but Sturdy Design.
- Very Low Noise Level.
- User – Friendly Electronic Controls.
- Non – Contact Type Sensor for Rub Counter makes it maintenance free.
- Silently operated blower to keep rubbing – surface clean, cool and moisture free.
