About This Product
Leather used in bookbinding has to survive a book being opened and closed many times without cracking. In a folding test a rectangular strip is bent repeatedly at the same location, and the outer folded surface is then checked for grain cracks. The tester has a fixed grip, an oscillating arm swinging through 180° and a flat blade, so the strip is folded at the same place each time. School Lab Equipment India supplies the Folding Tester across India and can export it to Italy, Trinidad and Tobago, Lithuania, Tajikistan, Moldova and Afghanistan.
