<p>PURPOSE:To close the internal surface of the end section of a resin hose. CONSTITUTION:Hot air is injected to the internal surface of the end section of a resin hose (6) to heat said internal surface, and the end section of the hose (6) is pressed to weld the heated internal surface. Accordingly, since hot air is injected to the internal surface of the end section of the hose (6) and said end-section internal surface is heated and melted, the molten sludge of a resin does not adhere on a heated cone as seen in conventional devices thus inhibiting the generation of a noxious gas due to the combustion of the molten sludge, then maintaining clean work environment.</p> |
