FREE-CROSS SECTION SPIRAL WOUND PIPE MAKING MACHINE HAVING AUXILIARY ROLLER MECHANISM, AND METHOD FOR MANUFACTURING LINING PIPE BY THE PIPE MAKING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a spiral wound lining construction device having a regulating frame, allowing the whole construction device to be smoothly advanced without deviation of the regulating frame, with prevention of the corotation with a forming frame, so that the operation for making a lining pipe can be smoothly performed.;SOLUTION: An auxiliary roller mechanism is installed at each of the corners of a regulating frame having a square and horseshoe shape. A stationary base plate is extended from the rear end of the regulating frame in the pipe axis direction. A roller holding frame is swingably installed through a pin shaft fixed and held to the outer front part of the stationary base plate. A contact roller which comes in contact with the inner surface of the lining pipe is installed on the roller holding frame. The roller holding frame is point-supported at the rear of the stationary base plate with a push-in bolt.;COPYRIGHT: (C)2015,JPO&INPIT
