a second half-reel (20) coaxial with and arranged opposite the first half-reel (10) in the longitudinal direction (X-X); said first and second half-reels (10;20) being displaceable in both senses of the longitudinal direction (X-X) from a relative position where the two half-reels (10;20) are closed in contact with each other in the longitudinal direction (X-X) for coiling the spool (5), to a position where the two half-reels (10;20) are separated from each other for unloading the finished and tied spool (5); and an assembly for tying the spool (5) by means of a strap (2). ## Claims ### Claim 1 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. ### Claim 2 (depends on 1) The coiling machine according to claim 1, wherein each of said first rotating half-reel) and the second half-reel has an end mounted on a support displaceable in both senses of the longitudinal direction (X-X). ### Claim 3 (depends on 1) The coiling machine according to claim 1, wherein each of the two half-reels comprises: a half-drum formed by arms having, connected thereto, longitudinal bar elements for supporting the pipes which are movable on the said arms in both senses of a radial direction from a closed position, close to an axis of rotation (X-X), to a fully open position, far from the axis of rotation. ### Claim 4 (depends on 1) The coiling machine according to claim 1, wherein each of the two half-reels comprises a cross journal mounted on the respective half-drum and formed by respective radial arms which carry flanges for axially containing and adjusting a height of the spool, said cross journals being movable in both senses of the longitudinal direction (X-X). ### Claim 5 (depends on 3) The coiling machine according to claim 3, wherein in the closed position of the two half-reels, free ends of the respective oppositely arranged bar elements of the two half-reels are axially rigidly joined together in contact with each other, forming a single body constrained at its opposite ends. ### Claim 6 (depends on 1) The coiling machine according to claim 1, wherein said first inner semi-channels have a form of an “I” parallel to the longitudinal axis (X-X). ### Claim 7 (depends on 1) The coiling machine according to claim 1, wherein the at least one first and the one second outer semi-channels have a substantially L-shaped form with respective arms parallel to the longitudinal axis (X-X) and arms at right angles to the latter and with their free ends directed towards the reel and suitable for connection to the first inner semi-channels present in an angular tying position. ### Claim 8 (depends on 7) The coiling machine according to claim 7, wherein at least one first and the one second outer semi-channels are arranged in a fixed angular position with respect to the two half-reels so as to form a closed ring for guiding the strap during each tying operation. ### Claim 9 (depends on 1) The coiling machine according to claim 1, further comprising a fixed base and wherein the said first rotating half-reel and the second half-reel of the reel are oppositely arranged with respect to a central plane (Y-Z) of symmetry of the coiling machine and are mounted on a respective support displaceable on the fixed base in both senses of the longitudinal direction (X-X).
