How To Solve The Problem Of Fabric Wrinkle When Sewing 842 Double Needle Machines

We can introduce how to eliminate this problem from the following two aspects.

(1) Machine adjustment Aspect

First of all, the cloth feeding teeth are adjusted to the front height and the lower part. Generally speaking, the transfer of the cloth teeth to the plane of the needle plate is parallel to the needle plate. If the feeding tooth is adjusted to the front height and then low (to the direction of the feeding direction), it will stretch and stretch will act as a drag wheel, which can reduce wrinkles. Otherwise, wrinkling will occur.

Secondly, the synchronization time of the feeding tooth is adjusted, and the synchronous relationship between the standard tooth feeding and tooth feeding is that when the needle is approaching the plane of the needle plate, the upper tooth plane of the cloth delivery is slightly higher than the plane of the needle plate or even with the plane of the needle plate. If the upper tooth plane of the cloth is lower than the plane of the needle plate, the stitched fabric will wrinkle easily. This is the common fault of the needle feeding double needle sewing machine. There is little problem in the non needle feeding double needle sewing machine. If there are conditions, it is possible to pay attention to the comparison between the two kinds of machines in the work, so it is not difficult to detect this phenomenon. When we debug the machine, we often encounter this phenomenon. The method we have taken is to remove the needle feeding device of the machine, which requires replacing the needle plate, sending the cloth teeth and pressing the foot. To solve these problems thoroughly, it is necessary to purchase models with auxiliary devices for mop wheels.

Thirdly, according to the thickness, hardness and hardness of the sewing material, the height of the feeding tooth can be adjusted reasonably. The cloth is highly adjustable and the cloth is strong, but it is easy to crease. It is suitable for sewing thick materials. The cloth is low in transfer, poor in delivery and not easy to wrinkle. It is suitable for thin materials.

(2) in machine Selection aspect

Combined with enterprise production and Fabric The best choice is to choose an economical and practical machine. The better the function is, the better. In view of the problem of wrinkling after sewing, it is very practical to choose two needle machines with ordinary underfeed cloth or two needle machines with mop wheels. For a garment enterprise, the performance of sewing machines is often limited. When it comes to equipment selection, it is difficult to make the right choice. For this reason, it is recommended that we should first understand the information of similar equipment and the capabilities and reputation of the equipment manufacturer, and then purchase a small number of equipment to try it out. After everything is clear, we will buy it in batches. This will not cause too much trouble and loss to the work.
