Abstract

A winding machine ( 1 ) includes a main body ( 20 ), a first arm ( 40 ), and a second arm ( 50 ). The main body ( 20 ) moves toward a winding direction front side as a profile strip ( 100 ) is added, while rotating at a winding direction front end portion of a formed pipe member ( 4 ). The first and the second arms ( 40 ) and ( 50 ) are supported by the main body ( 20 ) respectively at positions away from each other in a circumference direction of the formed pipe member ( 4 ), and extend toward a winding direction rear side between an existing pipe ( 2 ) and the formed pipe member ( 4 ). The first arm ( 40 ) includes a first restricting portion ( 43 ) that comes into contact with a winding direction front side of a reinforcement member ( 120 ) provided to the profile strip ( 100 ) forming the formed pipe member ( 4 ) via the profile strip ( 100 ). The second arm ( 50 ) includes a second restricting portion ( 52 ) that comes into contact with a side of the reinforcement member ( 120 ) provided to the profile strip ( 100 ) forming the formed pipe member ( 4 ) opposite to the side to be in contact with the first restricting portion ( 43 ), via the profile strip ( 100 ).

First claim

1 . (canceled)

2 . 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 pipe 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 pipe member, directly or via the profile strip.

3 . The winding machine according to claim 2 ,
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 pine 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.

4 . The winding machine according to claim 3 ,
wherein the engagement rib extends in an inclined manner from the width direction front side end portion of the profile strip to have a portion more on the front side disposed more on an outer side, and wherein the first guide portion extends in an inclined manner from a winding direction rear side end portion of the first arm to have a portion more on the winding direction front side disposed more on an inner side, so that a distal end portion of the first guide portion comes into contact with a winding direction rear side of the engagement rib of the second end portion of the profile strip.

5 . The winding machine according to claim 3 , wherein the first arm further includes a third restricting portion that comes into contact with a winding direction front side of the reinforcement rib of the first end portion of the profile strip.

6 . The winding machine according to claim 3 , further comprising a second arm that is supported by the main body at a position away from the first arm in a circumference direction of the pipe member and extends toward the winding direction rear side between the existing pipe and the pipe member,
wherein the second arm includes a second restricting portion that comes into contact with a winding direction rear 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.

7 . The winding machine according to claim 6 , wherein the second arm further includes a fourth restricting portion that sandwiches the reinforcement member of the first end portion of the profile strip with the second restricting portion in the winding direction, by coming into contact with the winding direction front side of the reinforcement member directly or via the first end portion of the profile strip.

8 . The winding machine according to claim 6 further comprising a roller that is rotatably supported by the main body and has a flange that comes into contact with the winding direction front end of the pipe member.

9 . The winding machine according to claim 6 , wherein the second arm further includes a second guide portion that comes into contact with the engagement rib of the second end portion of the profile strip and causes the engagement rib to engage with the reinforcement rib of the first end portion of the profile strip.

10 . The winding machine according to claim 9 , wherein the second guide portion extends in an inclined manner from a winding direction rear side end portion of the second arm to have a portion more on the winding direction front side disposed more on an inner side, so that a distal end portion of the second guide portion comes into contact with a winding direction rear side of the engagement rib of the second end portion of the profile strip, and has a shape different from a shape of the first guide portion.

11 . The winding machine according to claim 2 ,
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.

12 . The winding machine according to claim 4 , wherein the first arm further includes a third restricting portion that comes into contact with a winding direction front side of the reinforcement rib of the first end portion of the profile strip.

13 . The winding machine according to claim 4 , further comprising a second arm that is supported by the main body at a position away from the first arm in a circumference direction of the pipe member and extends toward the winding direction rear side between the existing pipe and the pipe member,
wherein the second arm includes a second restricting portion that comes into contact with a winding direction rear 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.

14 . The winding machine according to claim 5 , further comprising a second arm that is supported by the main body at a position away from the first arm in a circumference direction of the pipe member and extends toward the winding direction rear side between the existing pipe and the pipe member,
wherein the second arm includes a second restricting portion that comes into contact with a winding direction rear 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.

15 . The winding machine according to claim 7 , wherein the second arm further includes a second guide portion that comes into contact with the engagement rib of the second end portion of the profile strip and causes the engagement rib to engage with the reinforcement rib of the first end portion of the profile strip.

16 . The winding machine according to claim 8 , wherein the second arm further includes a second guide portion that comes into contact with the engagement rib of the second end portion of the profile strip and causes the engagement rib to engage with the reinforcement rib of the first end portion of the prof
