Patent ID: 8092204

Claim:
An apparatus for inflation extrusion molding of pressure-sensitive adhesive sheet, said apparatus comprising: a plurality of extruders; a die into which a pressure-sensitive adhesive and a resin material extruded respectively from the plurality of extruders are respectively introduced and which extrudes from an ejection opening a cylindrical body comprising a plurality of resin material layers and inflated to a predetermined diameter in accordance with an inflation method; and two stabilizers facing each other at a predetermined angle through which the cylindrical body extruded from the die is passed to be deformed into a flattened elliptical shape having a predetermined width, wherein the stabilizers each have a plurality of air floating portions each of which blows air toward the cylindrical body and the flattened elliptical shaped body; and the stabilizers rotate in one direction around the central axis of the cylindrical body; and wherein the air floating portions each have an indentation formed at a surface of the stabilizer and an air outlet provided in proximity to a center of the indentation, whereby the air blown from said air outlets spreads over interiors of said indentations to act as a contact pressure to float the sheet.
