A laboratory corrugating machine for producing a sample to evaluate flat crush resistance of corrugating. To determine the flat crush resistance / CMT value of a packaging or similar grade of paper

For producing a sample to evaluate flat crush resistance of corrugating medium. ‘A’ fluting rolls are heated up to 176 0C and maintained a constant temperature by Digital temperature Indicator – cum – controller.

the laboratory model provide the standard flutes as per commercial production. The flat crush resistance / CMT value is the force required to crush the flutes of the corrugated paper, the force being applied perpendicular to a plane tangential to the flutes as per standard testing conditions.

Number of teeth:               84 teeth

Depth of teeth:                  4.75

Revolutions of flute rolls: 4.0 per min

Temperature:  Adjustable and thermostatically controlled

                         up to 200ºC

Force between rolls:spring loaded force adjustable to 10 kgf. ±1
