Collapse tester for Paper Tube

Paper tubes used for winding yarn, shall have adequate mechanical strength. One of the tests used for ascertaining the mechanical strength of paper tubes is the collapse test. In this test, a test specimen taken from the sample of paper tube is placed on a rigid flat metallic plate and pressed against another rigid flat metallic plate. The maximum force required to collapse the tube is then measured.

GSM Balance (Quadrant Scale)

The weight per unit area or grammage of any material in form of sheets is usually expresses as its GSM, that is its weight in grams per square metre of its area. It is one of the most important parameters to determine the quality of any paper. In addition to paper, it can also be used for evaluation of grammage of fabrics, coated fabrics, felt, plastic films and sheets, etc.

Scale A 0 -160 x 0.5 GSM (sample size 25 x 25 cm)
Scale B 0 - 1000 x 4 GSM (sample size 10 x 10 cm)
Model B
Scale A 0 - 300 x 1 GSM (sample size 20 x 25 cm)
Scale B 0 - 600 x 2 GSM (sample size 20 x 12.5 cm)

Sizing Tester (Cobb Apparatus)

The amount of water absorbed by any paper is dependent on various characteristics such as its sizing and porosity etc. The sizing of paper can be determined by conducting a water absorption test with the help of a Cobb tester. In this test the weight of water absorbed by a known area of the paper under test in a specified duration of time is determined, from which the sizing characteristic is evaluated. However, this method is not recommended for determination of sizing characteristic of writing paper.

Thickness Gauge for Paper

The standard thickness of any sample of paper or paper board is measured by placing one or more test specimens taken from the sample under test on a flat anvil and pressing it down with the help of a circular indenter applying a pressure of 1 0.1 kg/cm2 on the test specimen. The diameter of indenter used for measuring the thickness is between 14 and 16.5 mm, while the pressure is applied by means of a dead weight to give more consistent readings.

Bursting strength tester with two pressure gauge

Bursting strength of any material such as fabric, leather, paper etc. is its strength under multi-directional force and is defined as the hydrostatic pressure required to produce rapture of the material when pressure is applied at a controlled increasing rate through a rubber diaphragm.

Schopper Folding Endurance Tester

Folding or creasing plays a very important part in life of paper. Almost all varieties of paper are subjected to either single or repeated folds in the course of their application. Determination of folding resistance is thus of prime importance in assessing suitability of any paper for the end use. Folding resistance is usually determined by either the MIT folding endurance method or by the Schopper folding endurance method. While the former is suited for any thickness of paper up to 1.25 mm, the latter is generally used when the thickness of paper is less than 0.25 mm.
