FZ/T 93030-2007Textile machinery and accessories. Cones for cross winding. Technology terms (English PDF)

Foreword

Instead of the standard FZ/T 93030-1994 "cross winding winder with conical tubes" in the part, not in place of covering cross Main dimensions fork with conical winding bobbin, tolerances and marking. GB/T 20035-2005 is half cone angle of 3 ° 30 ', 4 ° 20' and 5 ° 57 'cross Fork with conical winding bobbin dimensions, tolerances and the national standards. Cross winding included with main dimensions recommended values cone bobbin GB/T 20035 Part 1, its dimensions, tolerances and marking according to different half cone angle are included in Part 2 GB/T 20035 of ~ Part 5, are listed below international standards and the structure of the national standard corresponding to.

GB/T 20035-2005 "Textile machinery and accessories with a conical cross-wound bobbin"

--- Part 1. Recommended main dimensions value (ISO 8489-1:1995, IDT);

--- Part 2. half cone angle of 3 ° 30 'cone bobbin dimensions, tolerances and marking (ISO 8489-2:1995, IDT);

--- Part 3. half cone angle of 4 ° 20 'cone bobbin dimensions, tolerances and marking (ISO 8489-3:1995, IDT);

--- Part 4. half cone angle of 4 ° 20 'stained with conical bobbin dimensions, tolerances and marking (ISO 8489-4:1995, IDT);

--- Part 5. half-cone angle of 5 ° 57 'cone bobbin dimensions, tolerances and marking (ISO 8489-5:1995, IDT).

Compared with this standard FZ/T 93030-1994, the main changes are as follows.

a) by deleting the half cone angle of 9 ° 15 'cone bobbin size and gauge its provisions;

b) by deleting according to the pipe material, the small end of the structure, classification provisions of the semi-cone angle conical tube and associated Figs. 1 to 8 and Table 1 ~

Table 3;

c) the deletion of the "mark of the tapered tube method" requirement;

d) increase "substantially conical tube size, limit deviations" and its measuring "gauge dimensions, tolerances and the use of" should be consistent GB/T 20035.2-2005, GB/T 20035.3-2005, GB/T 20035.5-2005 provisions of Chapter 5;

e) In the inspection rules, add "There is one or more than one failure, is substandard goods," the decision rule;

f) In the inspection rules, add "In a sample of units" description;

g) In the inspection rules, the type of test items to increase the quality of testing, the substandard quality level of 20, classified as substandard C;

h) by deleting the chapter on packaging box predetermined and packaging Pictorial marking tied;

i) by deleting "Appendix A inner diameter measuring method";

j) other necessary editorial changes.

The standard proposed by China Textile Industry Association.

This standard by the National Standardization Technical Committee Textile machinery and accessories.
