Abstract

PURPOSE:To provide adhesive and smooth film by coating liquid over the quenched surface of both edges of a sheet of fused polymr complex pushed out of a die when the above sheet is given a rectangular displacement by an air bearing and introduced to a quenching surface. CONSTITUTION:A fused sheet 4 pushed out of a die 1 arrives at a cooling roll 2. During this process, the fused sheet is displaced from a ordinary catenary course to a course more rectangular to a quenching surface by a porous air bearing. Air or nitrogen, etc. is supplied from a pipe 5 to this bearing. By coating liquid over the surface of a cooling roll through a liquid coating device 6, necking-in of the film is decreased, more uniform and stable width and more uniform quenching are given to the film and therefore, smooth and transparent quenched films with no partial shrinkage and distortion are obtained.
