M.I.T. Folding Endurance Testers

M. I. T. FOLDING ENDURANCE TESTERS
Automatically test folding endurance properties of a
wide range of materials.
• Three different models
• Provides constant tension load
• Variable folding rates from 20 to 175 double folds
per minute can be furnished
• Test paper, plastic, leather, wire and other pliable
materials
With this machine, a pliable specimen is placed under a
constant tension load. The specimen is then folded to an
angle of 135° in either direction, at the rate of 175 double
folds per minute until the specimen is severed at the crease.
A variable folding rate option allows the operator to vary
the folding rate between 20 and 175 double folds per
minute.
Fig. TD 909-2. Model 2 Folding Endurance Tester with modified loading system and
digital counter is for use on materials with relatively high amounts on elongation.

Three Models to Meet Your Requirements
Ordering Information p/n: 31-23-00
Model 1 – For paper, leather, fine wire and other pliable
materials with comparatively low elongation characteristics.
This machine accepts standard 14 cm long by 15 mm wide
specimens. Holding jaws are available that will accept specimens varying in thickness from 0.01 to 0.07 in. Jaw size(s)
required should be stated when ordering.

Model 3 – Combination Paper and Plastics Tester
For maximum flexibility in testing both paper and plastic
specimens, this versatile folding endurance tester incorporates the features and capacities of both Models 1 and 2, as
described above, in a single unit.

The optional centrifugal exhaust fan draws conditioned room
air across the specimen and the head to accurately control
the temperature and humidity in the fold area in accordance
with TAPPI Method T 511 and ASTM D 2176.
Model 2 – For plastics and other materials with relatively
high amounts of elongation, this machine provides the same
operating principles and holding jaw options as the Model 1,
however, the loading system has been modified to automatically compensate for specimen elongation up to 100% on a 1
inch gage length. Loads of any desired magnitude from ½ lb.
to 5 lb. in increments of ½ lb. can be applied with full assurance of uniformity throughout the test.
