This machine counts the number of folds which a specimen under a specified tension will withstand before failure. It is used for testing money and map papers subject to repetitive folds. It is also
used for evaluating deterioration of paper due to aging. With different lower clamps, it can test a wide range of thickness. The number of folds to failure of some specimens may reach several thousands to several ten thousands. This machine counts folds by an optical sensor to show the fold number on the counter.
The resistance at the gears for producing reciprocating movement for folding is minimized. So the operation sound is very low.
Folding load : 5 to 15 N (0.5 to 1.5 kg) standard 9.8 N (1.0 kg) Rotating speed : 175 ± 10times.
Clamps : 0.25 mm (standard)
0.5, 0.75, 1.0, 1.25 mm (optional)
Referential standards : JIS P8115-2001, TAPPI T511om-02, ISO 5626
Power source : single-phase 100/110 VAC 50/60 Hz 3A.
with cooling fan
Outer dimensions : 430 x 300 x 420 mm
Instrument weight : 24 kg
No.2015-MR (with cooling fan)
In a test with a specimen whose number of folds to failure is large, the moisture in the specimen changes due to temperature rise of the folding portion, thereby reducing the folding endurance. This machine has an exhaust fan in front of the folding part to avoid temperature rise at the folding head. Except for this point, its specifications are the same as those of No.2015-M.
