22、 of the stitching.l/ (b) Thread breaks, or two or more consecutive skipped stitches or run-Offs, noted during inspection of the item (in-process or end item) shall be repaired by overstitching. The stitching shall start a minimum of one inch in back of the defective area (1/2 inch on box X and W-W s
23、titching), continue over the defective area and continue a minimum of one inch beyond the defective area onto the existing stitching. Loose or excessively tight stitching shall be repaired by removing the defective stitching, without damaging the materials, and restitching in the required manner.l/
24、Lhhen making the above repairs the ends of the stitching are not required to be backstitched. 3.7.1.2 Type 401 stitching. Thread tension shall be maintained so that there will be no loose stitching. Al1 repairs shall be in accordance with 3.7.1.1*1(a) and 3.7.1.1.1(b) except substitute 3/4 inch for
25、one inch wherever one inch appears. 3.7.1.3 Automatic stitching. Automatic machines may be used to perform any of the required stitch patterns provided the requirements for the stitch pat- tern, stitches per inch, size and type of thread are met, and at least three or more tying, overlapping, or bac
26、k stitches are used to secure the ends of the stitching. 3.7.1.4 Lubrication of thread. There shall be no lubrication of the thread by any means, prior to or during sewing. 3.7.1.5 Thread ends. All thread ends shall be trimmed to i/4 inch maximum length. 3.7.2 Location marks. Location and notice mar
27、ks shall not be drilled. 3.7.3 Snap fasteners and rivets. The lengths of the rivets and fasteners shall be determined by the contractor and shall effect a secure clinch of the assembled component s. 3.7.3.1 Setting. The hole shall be punched before inserting the fastener or rivet and shall be smalle
28、r than the outside diameter of the fastener barrel or rivet so that it must be forced through the hole. The fastener or rivet shall be securely clinched without cutting the surrounding material. When installed, the clinched end shall have a uniform roll that will effect a secure hold. All burrs shal
29、l be removed from the rivet. 3.7.4 Repairs. Repairs such as mends, darns, patches or splices are not per- mitted on the harness. 4 ,. .-,: 1-24 - . .
