<P>PROBLEM TO BE SOLVED: To provide an inflation extrusion molding apparatus, capable of suppressing generation of a crease, even if a resin material such as a pressure-sensitive adhesive sheet is deformed into a flat elliptical shape, and also capable of distributing protrusions R generated in a base material of the resin material. <P>SOLUTION: The adhesive sheet inflation extrusion molding apparatus 300 pushes out a resin material 10 from a die 120 into which the resin material is introduced by an inflation method, to inflate the material into a cylindrical shape having a predetermined diameter, and makes the cylindrical resin material 10 pass through between two stabilizers 200A and 200A facing each other at a predetermined angle, so that the adhesive sheet is manufactured. The stabilizers 200A each have an air floating part provided with a plurality of dents on the surface and facing an air blowing port of an air pipe at an opening of each dent, and the stabilizers 200A are made to rotate in one direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
