MIT Folding Endurance Tester (Improved Type)

This machine counts the number of folds, which a specimen will withstand before breaking. The upper end of the specimen is secured with the loading spring clamp and the other end with the folding clamp. The loading clamp applies a constant tension on the specimen. In this state, the folding clamp reciprocates to repeatedly fold the specimen until it breaks. The number of reciprocating actions counted is shown.

Product Name MIT Folding Endurance Tester (Improved Type)
Product Code KRK-2015-C
Standards/Methods JIS P-8115-2001, TAPPI T 511 om-02, ISO 5626
Manufacturer Kumagai Riki Kogyo Co., Ltd. ( KRK )
Availability from OpTest Exclusive to Canada, USA, and Mexico

The reciprocating part is provided for silent operation and reduced heating up.
The specimen is set on the upper chuck from the chuck front. This setting is the same for the lower chuck, ensuring accurate vertical setting.
The lower chuck returns to start position automatically when the specimen breaks.

Cooling Fan (optional)
In a test with a specimen whose number of folds to failure is large, repetitive folding actions will produce heat at the folding portion, causing an increase in temperature of the specimen, and diminishing water content, thereby reducing the folding endurance. This machine has an exhaust fan in front of the lower chuck to avoid temperature increase around the chuck.
