Precautions for repairing damaged tarpaulins with sewing machines

There are two types of tarpaulin damage from tarpaulin manufacturers. One is that both sides of the damaged tarpaulin can be dealt with naturally, and the other is that there is a gap in the natural flat state. We usually use a sewing machine to repair the damaged tarpaulin. , tarpaulin manufacturers remind everyone to pay attention to the following six points in the specific operation process. 1. Double suture should be used, the distance between the outer suture and the patch cloth is 15 mm to 20 mm, and the distance between the two sutures is 10 mm. 2. The tightness of the stitch is uniform and straight, the size of the stitch is 14 to 18 stitches/100 mm, and the back stitch at the starting and stopping points is not less than 3 stitches. 3. Waterproof glue should be applied to both sides of the pinhole repaired by the machine. 4. The rope pressing cloth should be repaired with a straight double-thread machine on both sides. The distance between the two needles near the pressing rope should not be less than 45 mm. And the return needle at the needle stop shall not be less than 50 mm. 5. After repairing, the middle of the rope cloth should be properly arched so that the waist rope can pass through. 6. The water hanging test at the sewing place is not allowed to seep, leak or leak. When using a sewing machine to repair damaged tarpaulins, it must be used in accordance with the operating specifications. You can sew with reference to the contents of the item.
