Schroeder twin folding tester
BACKStandards:
1、ISO 5626 Paper. Determination of folding endurance. 2、TAPPI 523 Paper. Determination of folding endurance. 3、NF Q03-062 Paper. Determination of folding endurance. 4、NF ISO 5626 Paper tests. determination of folding endurance.
Applications:
The instrument has two independently folding units with the same structure. Each unit contains a folding head, two spring dynamometer and a holder, which reduces half of the test time for a series of paper samples.
Product Information:
Understanding the repetitively folding resistance of paper and paper card is very vital for the determination the folding resistance of paper. Schroeder twin folding tester is designed to measure the folding resistance of paper. The drive motor is located on the base. The crank machinery with connecting rod and electronically controlled air circulation fan is mounted inside of the machine. Electronical control cells and pulse counter is set in the front of the base. The folding units is on the top, and each unit contains a folding head, two spring dynamometer and a holder.
Folding head is driven by silent wave motor, and cutter is precisely driven by a bearing, which ensures stable operation and good reproducibility of test conditions.
