MIT Paper Folding Endurance Tester is a testing apparatus to test Papers Folding Endurance, which is designed to be in accordance with related national standard GB/T 2679.5-1995, Paper and board.Determination of folding endurance (MIT Tester). MIT Type Paper Folding Endurance Tester has various functions, such as, parameter testing, parametric transformation, parameter regulation, parameter display, parameter memory and parameter print.The main functions are shown as following: compact structure, light weight, abundant functions, horizontal type and stable performance, so the tester is suitable for different paper and boards.
1.Measuring Range: 0 - 99999
2.Folding Angle: 135±2 Folding Frequency: 175±10 times/min.
3.Specimen: 15×150mm
4.The spring tension: 4.91N-14.72N, when every 9.81N tension is added, the compression of spring is 17 mm reduced at least.
5.The clearances between folding ports are 0.25, 0.50, 0.75 and 1.00mm (four ranges).
6.The tension change due to the eccentric rotating of clamping folding head should not be larger than 0.343N.
