Under the light system, the light shall be used for 0.2 days to test the performance of the instrument
6.2.1 Maximum Wiener speed
According to the provisions of Table 2, the high speed chain shall be installed in the test item pressure, and the crimping speed test shall be conducted. 6.2.2 Maximum stitch length and maximum stitch width QB 1175: 203-1
Other instruments only
Technical Table 2 is the test condition to avoid, and the two layers of test materials shall be made on the self-color and mountain shape shallow absolutely, not less than 0 milk Tan standard card! On the straight line, take the shortest continuous line traces, and use the water level technique to reduce the trace degree as much as possible: in the mountain shape, also take the three smallest width traces, and the line should not be flat or straight. 6.2.3 The needle plate, push plate opening and closing, and needle plate should not be lower than the working surface of the machine.
6.2.1 The gap between the needle and the needle hole of the needle plate
Turn the upper wheel by hand, whether the machine is at the output or the platform point, it is a relatively designed move, 6.2.5 The effect of loosening the line
is to turn the upper wheel to a higher point or a higher point, according to the instructions for keeping the needle hot, when the needle passes around the control line, the line is pulled down, and the line is locked. When the line is inserted and pulled, the distance between the bottom dial plane and the wire segment is at least 20m. It is determined by cutting the wire nail and the hook on the head with a real object. The silicon code can travel away from the platform. 6.26 Winding performance
With the most pure selection test, the final line diameter is measured with a vernier of not less than ±0m. 6.2.7 Adjust the machine plan
In the "approximate performance test" item, the control production is not complete. 2.8 With needle base point displacement, flower spring selection, buttonhole device mechanism adjustment in the "actual performance test" change, according to the "product actual performance test book provisions of the law. 6
