<p>PURPOSE:To efficiently and continuously manufacture a broad synthetic resin film by treating one face with ah acrylic resin like an agricultural vinyl chloride resin-based film and connecting in the cross section by heat fusion. CONSTITUTION:A device comprises endless feed mechanisms 2A, 2B for forming a continuous feed passage 6 for feeding two synthetic resin films S1, S2 by pinching them, a reel mechanism 100 for supporting a winding roll R3 of a connecting synthetic resin film S3, hot plate type heating units 71A, 71B, 72A, 72B opposed to the continuous feed passage 6, and cooling units 73A, 73B.</p> |
