This extremely easy to use instrument has been manufactured to determinethe static
and kinetic friction of plastic film, sheeting and paper and other sheeted material using
the horizontal plane principle.
The coefficient of friction (COF)is anumber which represents the frictionbetween two
surfaces. Friction is aresisting force relating to molecularstructure of a surface of one
materialas it slides over the surface of thesame or another material. Moleculesfrom one
surface link with molecules from the other. If you press the objects together more tightly,
you push the surfaces closer together, joining more molecules. This is why friction is
proportional to the normal force, how tightly the surfaces have to push on each other

The C.O.Friction Tester can measure Static COF from a resting position and continue to move

The C.O.Friction Tester employs a moving sled with a stationary table. The table has a clamping
system preventing slippage of the test piece during a test. The sled is lowered onto the table
by means of an elevator system, which places the sled so as both test surfaces meet
simultaneously,xa tej neeg teb xov tooj yuam kev, uas tej zaum yuav cuam tshuam tau ntawm qhov kev xeem.
Different COF results in paper can be influenced by antiskid agents, relative humidity and
calendering.The accurate COF data obtained by using the C.O.Friction Tester aids in assessing
problem situations such as:
Roll winding problems. E.g.: crepe wrinkles, dishing, telescoping.
Web tracking problems and print misregister.
No feed or multiple feed during sheet feeding. E.g.: printing, envelopes or cartons.
Registration errors in diecutting or converting.
Corrugator runnability problems of several kinds.
Sliding on conveyor when product should not, or vice versa.
Stack or Pallet stability. e.g.: cartons, sheets, sacks, printed material.
Kev pab cuam:
Designed specifically for friction measurement.
Provides the user a means of determining the key COF parameters for their product.
Useful for quality control.
Precise and repeatable tests.
Able to test and inspect incoming materials.
Conforms to ISO 15359
Extremely easy to operate.

By default, if the operator does not choose to select or adjust any test parameters,the
system will automatically load parameters specified by ISO15359.The operator also has
the opportunity of recording Sample Identification, where data suchasOperator Name,
Description, Part Number, Standard, Date and Place can be recorded with theCOF results
for future reference. Once all relevant data has been selected and recorded, the simple
process of loading the sample ready for testing is achieved with the easy clamping system
and sled carriage. With point and click mouse control, OK will initiate the drive mechanism,
starting the test operation.
The software package is user friendly, prompting the operator through all processes, including
Accepting or Declining each individual test. This allows for any errors, such as a faulty sample,

COF of selected test runs, a force time graph is displayed. The X and Y axis of the graph can

Besides the graph, there are two other panels containing real-time data, the output panel
and the COF panel. The test results panel shows the results accumulated during each repeat
and is updated at the end of each slide. A statistics panel shows the means of both static
and kinetic forces, both frictional and coefficient of friction.
