Ton bag, also known as container bag, is a commonly used packaging material for daily transportation of goods. Due to frequent use and special raw materials, it is more common for ton bags to break. At this time, we need to repair it quickly. Only then can it be put into normal use. So are there any tips for quick patching?
Container bag sewing machines refer to the sewing machines used in the container bag sewing process, including lock stitch sewing machines, chain stitch sewing machines, and hemming stitch sewing machines. Lock stitch sewing machines are mainly used in two categories: shuttle shuttle and rotary shuttle. Because heavy material container bags need to be sewn, the important parameters include sewing thickness, presser foot lifting height, turning ability, etc. in addition to sewing speed. Container bag sewing machines are generally large-scale machines. Because the sewing thickness imposes constraints on the machine, the container bag sewing machine is required to have excellent fatigue resistance coefficient and sewing stability. In addition, most container bag sewing machines are differentially fed or synchronously fed, which greatly improves the sewing life of the sewing machine.
The rupture point of the 1-ton bag is the handle of the ton bag. At this time, it is important to note that this is the stress point and the place where cracks often occur. There are two quick repair methods. One is to cut off the cracked part at the original crack, and then Use a sewing machine to patch with double threads, and the distance between the two stitches should be less than 10MM. The other is to use a ton bag patch of the same material to patch the cracked area, with a straight double-line machine patch, and the distance between the outer suture and the periphery of the patch cloth is not less than 20MM.
The 2-ton bag is damaged on the side or bottom. At this time, it can only be repaired by using a sewing machine or a flat car. The butt seal is 3 needles and 5 threads. At this time, please note that the size of the patch should be larger than the size of the damage, and the distance must not be If it is less than 20MM, if the labor is relatively heavy, it is recommended to carry out double repair on the inside and outside, so that the repaired ton bag will be stronger.
