Non-standard is the initial machine of QB1576-1992T industry chain. Repair of GL type chain sewing machine head: Compared with Ningning QB1576-1992, the main changes are: the original standard name is changed to "Industrial chain sewing machine head"; the "reference mark" of the standard frame 2 is modified; the "technical identification" of the third item of the standard is cancelled; the "basic number" of the original standard is increased and revised; the requirements for "material appearance quality" are added: for example, the "thick material key" requirements and corresponding test methods in the performance are added; the stretch performance is "continued to the test length" and the operation performance is revised to 1000 mm! The "noise", "maximum sewing speed is not less than 1000 stitches/minute, the noise level should not be higher than 80dB (A) at night: when the maximum sewing speed is less than 2000 stitches/minute and less than 3000 stitches/minute, the noise level should be 83B (A). The content of the "method" has been changed: the product standard number logo has been added to the "evil fishing pool". The test rules shall be carried out in accordance with the provisions of GB/T282R.1-2003 and R/T28292.002. This standard is issued by the China Light Industry Association. This standard is the national standard for sewing The center belongs to: Pi'an Industrial Co., Ltd., South China Sewing Group Co., Ltd., Zhongshan Sewing Zone Co., Ltd., Shangbang Economic and Technical Research Institute, National Sewing Machine Quality Inspection Center: The main operators of this standard are: Yu Shoujiu, Zhang Zai, Guo Meibi, Wu Wei, San Wei, and Zhang Jian. From the implementation of this standard, it will replace the original light industry standard (QB/T1576: [992T Industrial sewing machine head with GL type sewing machine head.
