factory customized Electrical Circuit Tester - C0041 – COFriction Tester – Drick

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

to keep from breaking. This proportion is the coefficient of friction.

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

testing surfaces in a relative motion to give an accurate kinetic COF result.

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,eliminating any operator error, which may influence the results of the test.

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.

Benefits:
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.

Operation:
The C.O.Friction Tester Windows based software
allows the operator to set test parameters such as:
Number of Repeats
Number of Slides
Acceleration of Sled
Sled Weight
Maximum Speed
Force Delay

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,

to be deleted and not recorded as part of the final result. Rejecting a slide during a cycle of t

ests will not alter the sample number. Upon completion of a test cycle, involving the recording
COF of selected test runs, a force time graph is displayed. The X and Y axis of the graph can

be customised for the particular test being undertaken.

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.
