Fig. 1 is a flow chart illustrating a method for zonally controlling the thickness of a material layer for low dielectric glass fiber production according to an embodiment of the present invention. The embodiment of the invention provides a method for regionally controlling the thickness of a material layer for producing low-dielectric glass fibers, which comprises the following steps: step 1, enabling the feeding device to travel longitudinally and transversely. And 2, acquiring the paths and positions of longitudinal walking and transverse walking of the feeding device in real time. For example, the coordinates of location 1-location 10 are obtained. The feeding device changes the walking direction at the position 1-10 (as shown in fig. 2), for example, from longitudinal walking to transverse walking or from transverse walking to longitudinal walking. For example, the real-time acquired paths and locations may be transmitted to the DCS system via DP cabling. And 3, dividing the whole feeding area passed by the collecting and feeding device into a plurality of areas according to the collected path and position. For example, the entire dose area is divided into 30 zones (K1 to K30) as shown in fig. 2.
