<p>PURPOSE: A profile forming device for repairing a pipeline, a method for forming the profile, and a synthetic resin profile produced by the same are provided to prevent a bottleneck effect because synthetic resin powders are dispersed through a plurality of through-passages when upper and lower valve plates of a second hopper are opened. CONSTITUTION: A method for forming a profile for repairing a pipeline is as follows. A plurality of synthetic resin powders is stirred in a stirrer. The stirred synthetic resin powders are delivered to a first hopper(310) of a supply hopper. The synthetic resin powders are delivered to a second hopper(320) being arranged in the lower part of the first hopper by an opening and closing of a first hopper opening and closing unit(311). The synthetic resin powders are delivered to a screw transferring unit by an opening and closing of upper and lower valve plate parts(110,120). The synthetic resin powders are delivered to a reactor and fused. The fused synthetic resin powders are extruded in a mold unit so that the profile of a desired shape is formed. The profile discharged from the mold unit is cooled. A water-swelling water-stop material is stacked at one spot of the cooled profile.</p> |
