The Testing Times

This a ttachment , the S0991 is designed to test how card and paper folds, a small sample section is taken and placed under a retaining bar, this is then forced to fold using the fold bar at the back. A rotary digital encoder measures the rotation angle and compares it to the force measured on the loadcell . To ensure self-alignment cord is used to rotate the pulleys that move the folding bar. Used in the packaging industry this compares how easy is is to open your box of cereal in the morning and to see how strong the folds are...

A flexural test tells the tester how much force a specimen can withstand in the middle when supported at a distance (or its flexibility!). This test supports the specimen between two loose fitting ‘rollers’, the distance apart of which can be set for a specific test or specimen size. Once the sample is in place the anvil can be brought down just above the specimen. A variety of tests can then be performed. The specimen can be flexed a certain number of times to judge it’s elasticity or plasticity over a given time. The specimen could be flexed until it breaks, it could be flexed for a specific time and the responding force measured. This is a Heavy Duty system, which has been designed to suite the U-Series 100 kN System . It has a travel of 400mm from centre (800mm overall) and Ø10mm rollers. This can all be recorded in the software and multiple specimens can be tested.
