ABSTRACT:
An automatic gathering pre-shape machine has a main body and a gathering device. The main body can make plastic films formed into a circular shape with an annular flange formed around a top edge of the film. The gathering device allows a pre-shaped plastic film be blown toward an outer end of the barrel to hit a block wall and drop and mount around a tip portion of corresponding shelf to be gathered. Consequently, the plastic film may easily and automatically be gathered from the main body. Therefore, the plastic films can be kept from being damaged and the pre-shaping process is accelerated.
