Abstract

A parison transfer apparatus includes a die core and at least two parison expansion rollers disposed below the die core and having a conical shape. The die core extrudes a parison having a form of a single sheet or cut into a plurality of sheets in an arc shape toward a space below the die core. The parison expansion rollers are arranged to abut against the vicinity of respective side end portions of the arc-shaped parison having the form of the single sheet or the plurality of sheets as a result of the cutting. The parison expansion rollers are configured to be rotated in a direction opposite to a downflow direction of the parison to pull the side end portion of the parison such that a width of the side end portion expands and a shape of the parison changes from the arc shape into a flat plate shape.
