摘要:
A tubular film manufacturing method includes the steps of winding a sheet film on a cylindrical member, cutting a winding end portion of the sheet film, and inserting the cylindrical member, on which the sheet film is wound, into a tubular mold member. The sheet film is molded into a tubular film by heating. In the inserting step, the cylindrical member is inserted into the tubular mold member while the winding end portion of the sheet film is pressed by an elastically deformable brush member.
