Embodiment approach

[0023] As a preferred embodiment of the present invention, the longitudinal stretching comprises the following steps: the mask sheet is heated to the stretching temperature on a preheating roller; the mask sheet is stretched longitudinally on at least two sets of stretching rollers, and The diameter of the stretching roller is small, and the stretching gap can be adjusted within a certain range, which can reduce the necking of the sheet; in order to avoid excessive shrinkage of the product during storage, the mask sheet is shaped on the heat setting roller after longitudinal stretching . During longitudinal stretching, the rotational speed of each roller must be kept constant. The longitudinal stretching system consists of many rollers. It is troublesome and unsafe to thread the film manually. Generally, the sheet threading system is used.

[0024]As a preferred embodiment of the present invention, the transverse stretching includes the following steps: first, heat in an air b...
