Winding machine

A winding machine configured to form a pipe member in an existing pipe by winding a profile strip having an elongated shape, the winding machine comprising:

• a main body that moves toward a winding direction front side as the profile strip is added, while rotating at a winding direction front end portion of the pine member;
• and
• an arm that is supported by the main body and extends toward a winding direction rear side between the existing pipe and the pipe member,
• wherein the arm includes a restricting portion that comes into contact with a reinforcement member provided to the profile strip forming the nine member, directly or via the profile strip,
• wherein the profile strip includes a reinforcement rib protruding on an outer side surface and an engagement rib extending toward a front side from a width direction front side end portion,
• wherein the arm includes a first arm, and
• wherein the first arm includes:
• a first guide portion that comes into contact with the engagement rib of a second end portion of the profile strip that is adjacent to and disposed on a winding direction rear side of a first end portion of the profile strip that is positioned at the winding direction front end of the pipe member including the profile strip previously formed in a pipe form, and causes the engagement rib to be engaged with the reinforcement rib of the first end portion of the profile strip;
• and
• a first restricting portion as the restricting portion that comes into contact with a winding direction front side of the reinforcement member provided to the first end portion of the profile strip, directly or via the first end portion of the profile strip.

• wherein the arm further includes:
• first and second arms that are supported by the main body respectively at positions away from each other in a circumference direction of the pipe member, and extend toward the winding direction rear side between the existing pipe and the pipe member,
• wherein the first arm as the restricting portion includes a first restricting portion that comes into contact with a winding direction front or rear side of the reinforcement member provided to the profile strip forming the pipe member, directly or via the profile strip, and
• wherein the second arm as the restricting portion includes a second restricting portion that comes into contact with a side of the reinforcement member provided to the profile strip forming the pipe member, the side of the reinforcement member being opposite to the side to be in contact with the first restricting portion, directly or via the profile strip.
