Application
Vertikaalne tõmbetesti is a constant-rate-of-elongation equipment which is used for the determination of the tensile strength, stretch at maximum force and tensile energy absorption, tensile stiffness of paper, paperboard, tissue paper and tissue products. It also calculating the tensile index and the tensile energy absorption index.Vertical Universal Tensile Tester is a type of Paper Board Testing, please contact us to purchase!
Test Principle
A test piece of given dimensions, is stretched to break at a constant rate of elongation using Vertikaalne tõmbetesti that measures and records the tensile force as a function of the elongation of the test piece. From the recorded data, the tensile strength, the corresponding stretch at maximum force and the tensile energy absorption can be calculated.

Technical Features
This unit is under PLC control (with industrial-level stability) and operated through an HMI touch screen. The use of a precision ball lead screw mechanism ensures consistent and accurate speed and displacement control. It features a specially designed program catering to tests of paper.
