At present, technology is developing rapidly and industrial production equipment is becoming increasingly advanced. Taking the fully automatic sewing machine for producing lifting belts as an example, these devices greatly improve work efficiency and ensure the exquisite sewing of lifting belts. However, not all lifting belts are completed by sewing machines, and large tonnage flexible lifting belts are an example.
The production process of large tonnage flexible lifting belts is the same as that of conventional tonnage flexible lifting belts. Just because the amount of polyester yarn required for large tonnage flexible lifting belts is tens of times that of ordinary flexible lifting belts. Therefore, the weight of the flexible lifting belt is relatively large, and the sewing process is difficult for one person to complete alone, requiring several people to work together.
Due to the large size of this type of lifting belt, it is difficult to fix it with a sewing machine. At this time, the advantage of high precision of the sewing machine cannot be fully utilized, and the accuracy of the flexible lifting belt sewn will not be guaranteed. More of it will require manual sewing to achieve better results.
So lifting belts are not just sewn with sewing machines. Different sewing methods are used for different specifications of lifting belts to maximize their value.
