We Offer Folding Endurance Tester , Kohler Molin Type. Folding Endurance Tester is intended to determine the Folding Endurance of all kinds of paper card board, foil and film and is applicable to the paper up to 0.15 mm in thickness having a tensile strength greater than 1.3 knm. Two test samples can be tested simultaneously. The numbers of folds are stored into the counter, which are stopped counting automatically when the test sample breaks. Equipment conforms to the SCAN -P17:77 Standard.

Corrugated and solid fiber board boxes are subjected to compressive forces when stacked and during transportation. It is vital to determine the Compression Strength of the Box in order to make sure that the Box will be able to resist the anticipated compressive forces and to determine the load that the Box will be to withstand during transit and storage. This equipment is designed to measure ability of the container to resist external compression loads during transit and storage. Compression Strength Tester also serves as a useful index of overall quality of the material and workmanship of the Box. Suitable for Testing as per following Standards. IS 7028 (PART VI)-1973 7028 (PART IX)-1975 TPPI T-8040 om-89 ASTM D 642-90

SPECIFICATIONS:- Integrating spheres diameter 15 cm.Total area of aperature in sphere- less than 7.5 % of the sphere area.Gloss Type subtends half angel of 15.5 surrounding emerging sample beamSample aperature circular with 34 mm diameter. Sample area of view circular with 30 mm diameter. Accepted reflected beams perpendicular within 00 to 10 and confined to cones of 3.5 half angles. Accuracy of ISO standards + 0.3%.Max Photometeric Linearity Error 0.1% Power Supply 230 + 5% volts, 50VA, 50 Hz. BRIGHTNESS:- ISO Brightness is the reflectance of blue light (with an affective wave length of 457nanometers) measured under carefully controlled geometric, photometric conditions. OPACITY:- ISO Opacity, in accordance with ISO standard 2471 measures with this meter directly.R0 is obtained by measuring the reflectance of a single sheet backed with a black material.R00 contained by measuring single sheet backed by multiple sheets of the same material. ISO opacity, which is the ratio R0 R0c is automatically read out by the instrument. Custom filterSelection provides accurate agreement with the ISO 2471 spectral response function at effective wave length 557 nanometer. COLOR MEASUREMENT:-Instruments measure the Tristimulus reflectance of the sample in percent by using the tristimulus filter.Brightness : Reflectance in percent with Blue filter of wavelength = 457 nm.R(x) : Tristimulus Amber (wavelength 595 nm) reflectance in percent.R(y) : Tristimulus Green (wavelength 557 nm) reflectance in percent.R(z) : Tristimulus Blue (wavelength 455 nm) reflectance in percent. From reflectance value color scale are calculated such as:-CIE Tristimulus value X, Y, Z.Color values in CIE Lx, ax, bx Or Hunter L, a , b.Dominant wavelength, Purity and Luminousity. (The symbol L, a, b are used to designate measured color value as follows: L represents lightness increasing from zero for black to 100 for perfect white; a represents redness when plus, greenness when minus, and zero for gray; and b represents yellowness when plus, blueness when minus and zero for gray).

A Core with in a roll of paper which has collapsed radically or the end is crushed axially from excessive thrust loads. Damage is due to hard impact received during handling & transit.Defective roll as a result it of surfacing rolls on end in an excessively high pile, which in turn causes the lower ends of the lower rolls to fail in axial direction. Specification:- To test the tube pressure increase by the force of air pressure by the pneumatic cylinder with control hand operated valve. Pressure shows by the pressure gauge with fixer pointer in unit kgcm2.After rupture the conetube the fixer pointer stops and shows the gauge reading in kgcm2.Different jig will be used for different size of conetube.Maximum load capacity 1000 kgf.
