Overview
This machine is a factory-sold NBC-7125 leather folding test machine, which is suitable for testing the folding endurance of various leather materials, leather materials and fabrics. After clamping the inner and outer sides of the tested material and repeatedly twisting for a certain number of times, observe the damage of the tested material. It is suitable for thin objects such as uppers, clothing materials, and bags.
Features
1. The folding speed is stable at 100 +/- 5cpm.
2. Equipped with a 6-bit electronic counter
3. With 12 sets of fixtures
4. The bending angle is fixed at 22.5 °
5. The size of the test piece is 70x45cm.
6. Compact shape, size 52 * 64 * 40cm
7. weight about 60kg, easy to move
8. Power supply voltage is AC 220V/50Hz, with strong versatility
Principle
By clamping the inner and outer sides of leather, leather or fabric in the fixture, the machine repeatedly twists the material at a speed of 100 +/- 5cpm, and the bending angle is 22.5 °. After a set number of times, observe the damage to the surface or structure of the material to evaluate its bending performance.
Applications
For vamp, clothing, bags
Standards
BS-3144、JIB-K6545、QB1873、QB2288、QB2703、GB16799-2008、QB/T2706-2005
Steps
1. Cut the test piece to a size of 70x45cm
2. Correctly hold the inner and outer sides of the test piece in 12 sets of clamps
3. The number of twists required to set the counter
4. Start the machine and make repeated twists and turns at 100 +/- 5cpm
5. Automatically stop after reaching the set number of times
6. Remove the specimen, observe and record the damage
Notice
• Power supply voltage is AC 220V/50Hz to avoid voltage instability
• Check whether the fixture is firm before operation to prevent the test piece from peeling
• The size of the test piece must strictly meet the requirements of 70x45cm
• Regularly clean machine surfaces and fixtures to keep equipment tidy
• Non-professionals should not disassemble or adjust the internal structure
• Turn off the power supply in time after use to ensure safety
