adjust the film blowing thickness

Adjust the film blowing thickness. The width is determined by the amount of air in the bubble. If it is not wide enough, add air into the bubble, and if it is too wide, deflate. The thickness is regulated by the main engine and traction. If the main engine is pulled slowly, it will be thin. On the contrary, if the main engine is pulled quickly, it will be thick.

The thickness is adjusted on the membrane head, and the width is adjusted by inflating the air pump. You can also buy a wide range controller

When you adjust the main engine after the width is appropriate, the film will generally become wider (related to the cooling of the discharge. When the discharge is larger, the cooling does not keep up, which leads to higher film bubbles, and when the discharge is smaller, it is just the opposite). When the auxiliary engine is fast, the film has become narrower. In fact, it is only necessary to solve the problem that the position of the film bubbles does not change during the acceleration and deceleration of the main and auxiliary engines. The problem I encountered with the instability of the film bubble is that the temperature of the film mouth is not matched with the cooling air volume. Generally, the air volume is too large, so it is relatively simple to adjust the air inlet.
