Specimen Preparation for Paper and Cardboard

Good testing starts with good specimen.

Truism, one might say. But so often the devil is in the details. Testable specimens are produced by clean cuts, precise angular specimen, parallelity, service life of knives and quick work. To ensure the practicality of the cutting device, we leave the production to our partners, who do this work every day.

Advantages and features

  • Specimens are manufactured with better than 0.05 mm parallelity.
  • With optimum adjustment (rpm and carriage advance), ECT values 15–20% above the standard value can be obtained.
  • Double saw blades with special toothing for optimum cutting performance and long service life
  • Rotational speed steplessly adjustable in range from 5,000 to 24,000 rpm.
  • Dead weight employed to ensure constant force application to specimen during sawing process
  • Carriage advance operates automatically (manually adjustable), allowing specimens to be sawed under identical conditions
  • Digital display with elapsed time counter and meter for monitoring wear on saw blades
  • Connection for external extractor unit.

Range of application and function description

The ECT specimen saw with automatic cutting guide is used to produce standard-compliant specimens for the edge crush test (ECT) on corrugated cardboard to EN ISO 3037.

Conditioning of board specimens must be performed in accordance with ISO 187.

A sharp blade is used to cut strips to the following dimensions: 100 mm perpendicular to the direction of rotation of the corrugator and 70 to 300 mm perpendicular to the corrugator rotation. The specimen sheets are then clamped in the saw.

A dead weight is used to ensure constant force distribution into the specimen material in the saw.

The specimen is sawed at a preset rotational speed. The automatic carriage advance enables exact reproducibility for a wide range of specimens, as all are sawed under the same conditions.

Following cutting the specimen is ejected and the next specimen can be sawed.

Paper thickness

Thickness measuring instrument_corrugated cardboard

The Right Paper Thickness

Paper thickness is measured for various reasons.

The degree of stiffness of the paper and cardboard depends on the thickness, thus accurate measurement of the thickness will determine the degree of stiffness of the cardboard and the processability in the packaging or printing machine. If the mass per unit area and thickness of the paper are known then the weight-related volume can be calculated. This is important for transporting larger quantities and for the processing of these materials.

Standard working digital thickness measuring instruments that transfer measured values to systems for further processing save time and ensure secured data.

Significant advantages and features

  • Stamp area, weight loading and lowering speed for all established standards are available on request.
  • Individual and series testing.
  • PC connection via integrated RS-232 or USB interface.

Circular Cutters

Advantages and features

Specimen preparation_circular cutter

Circular cutters produce circular specimens with defined surfaces for the flat crush test (FCT) to ISO 3035 and EN 23035 on paper, board and corrugated board. A quarter-turn of the handle causes the four blades to cut out a circular specimen.

Circular cutters are supplied complete with cutting pad and 10 replacement blades.
