Coiling Pipes in Spool Form and Tying Said Spool

A coiling machine for coiling pipes in a form of large-size heavy spools, comprising:

• a reel rotating about a longitudinal axis (X-X) for coiling the pipes fed to the reel in a feeding direction (Y-Y), wherein said reel comprises:
• a first rotating half-reel;
• a second half-reel coaxial with and arranged opposite the first rotating half-reel in the longitudinal direction (X-X);
• said first rotating half-reel and the second half-reel being displaceable in both senses of the longitudinal direction (X-X) from a relative position where the two half-reels are closed in contact with each other in the longitudinal direction (X-X) for coiling the large-size heavy spools, to a position where the two half-reels are separated from each other for unloading the large-size heavy spools;
• and
• wherein the coiling machine further comprises:
• an assembly for tying the large-size heavy spool by means of a strap, the assembly comprising:
• first inner semi-channels connected to each half-reel in predefined angular positions thereof;
• at least one first and one second outer semi-channels which are rotationally fixed, respectively connected to the first rotating half-reel and the second half-reel in a predefined angular position thereof, axially detached from each other and axially displaceable in the longitudinal direction (X-X) together with the two half-reels;
• a tying unit for operation of the strap, connected to the first inner semi-channels and at least one first outer semi-channel.
