Abstract

PURPOSE: To obtain a curled part with stable shape in a shorter period, by pressing the container into a preheating part from a container feeding part and after the flange part is preheated pressing in further upto the curling part to curl the flange part.
CONSTITUTION: The mold is adjusted to an optimum temp. according to the material of a plastic container to be curled. The plastic container 5 is inserted into a rotatable mold 7 for inserting the container under pressure from a container lead part 1 to a preheating part 2 with or without rotating the container. Then only the feeding is interrupted and the flange part is preheated. Thereafter the container 5 is further pressed in to cause a curling along the curling part. The most suitable thickness for the sheet for the container, is ≥0.2mm and the most suitable temperature for the mold is around that of the heat distortion temperature of the material of the plastic container.
