This is a tester for resistance to folding of a sheet of paper or film. The specimen is inserted into a slit in the reciprocal movement metallic plate where the specimen is held at the right and left ends to be given light tension. The holding line of the specimen is subject to repeated reciprocal movement, and leads to fracture.
The number of reciprocations to cause fracture is displayed as Schopper folding resistance.
The number of reciprocations to cause fracture is displayed as Schopper folding resistance.
