PURPOSE: To perform reliably reheating treatment by introduction of steam in such a case where a resin pipe is used for a lining of a pipe line by preventing especially the resin pipe wound around a lower layer part of a drum from becoming flattened excessively and being in a clogged state under the influence of winding pressure or heat through the resin pipe to be wound around the resin pipe at the time of winding on a wind-up drum in a multiple state under a state wherein an extrusion molded long-sized resin pipe is reheated and made to soften. CONSTITUTION: At the time of wind-up of a resin pipe 1 which is extrusion molded and softened by reheating around a drum D, directly after wind-up around the drum, cooling water 8 is sprayed on the resin pipe 1 through a cooling nozzle 7 and continuous wind-up is performed while cooling forcibly at a temperature lower than a heat deformation temperature. |
