Abrégé anglais


A process for forming a coil of scrap tubing includes the steps of forming a
turntable
having at least one longitudinal member extending upwardly therefrom,
extending a length of the
tubing to the turntable, rotating the turntable such that the tubing wraps
around the longitudinal
member so as to form the coil, and lifting the coil from the turntable that
above the longitudinal
member. An end of the scrap tubing from the reel is fixed to the turntable
prior to the step of
rotating. The longitudinal member includes a panel extending upwardly from the
turntable and
an arm pivotally mounted adjacent an end of the panel opposite the turntable.
The arm is
movable between a substantially horizontal orientation and a substantially
vertical orientation.

CLAIMS
1. A process for forming a coil of tubing, the process comprising:
forming a turntable having at least one longitudinal member extending upwardly
therefrom;
extending a length of the tubing to said turntable;
rotating said turntable such that the tubing wraps around said at least one
longitudinal member so as to form the coil; and
lifting the coil from said turntable and above said at least one longitudinal
member.
2. The process of claim 1, further comprising:
supplying a reel of the tubing in a location adjacent to said turntable;
extending an end of the tubing toward said turntable; and
fixing the end of the tubing at said turntable prior to the step of rotating.
3. The process of claim 1, said at least one longitudinal member comprising:
a panel extending upwardly from said turntable; and
an arm pivotally mounted adjacent an end of said panel opposite said
turntable.
4. The process of claim 3, further comprising:
pivoting said arm upwardly when the tubing wraps around said panel.
5. The process of claim 4, said arm movable between a substantially horizontal

orientation in a substantially vertical orientation, the process further
comprising:
moving said arm to said substantially vertical orientation prior to the step
of
lifting.

6. The process of claim 4, further comprising:
moving said arm to the substantially horizontal orientation prior to the step
of
rotating.
7. The process of claim 5, the step of lifting comprising:
lifting the coil above an upper end of said arm when said arm is in the
substantially vertical orientation.
8. The process of claim 3, said panel pivotally attached to said turntable,
said panel
movable between a vertical position and an angularly inclined position, the
process further
comprising:
moving said panel to said angularly inclined position prior to the step of
lifting.
9. The process of claim 1, further comprising:
extending the tubing through a levelwind, said levelwind positioned adjacent
to
said turntable; and
moving said levelwind while said turntable rotates.
10. The process of claim 1, further comprising:
clamping the tubing in a fixed position prior to the step of lifting; and
cutting the tubing so as to separate the coil of tubing from a remainder of
the
tubing.
11. An apparatus for forming a coil of tubing, the apparatus comprising:
a base;
a turntable rotatably mounted upon said base; and
at least one longitudinal member extending upwardly from said base, said at
least
one longitudinal member having an outer surface suitable for allowing the
tubing to wrap
-16-

therearound as said turntable rotates.
12. The apparatus of claim 11, said turntable having a slotted area therein,
said turntable
having a clamp positioned adjacent said slotted area, said clamp suitable for
fixing an end of the
tubing to said turntable.
13. The apparatus of claim 11, said at least one longitudinal member
comprising:
a panel extending upwardly from said turntable; and
an arm pivotally mounted adjacent an end of said panel opposite said
turntable,
said arm movable between a substantially horizontal orientation and a
substantially vertical
orientation.
14. The apparatus of claim 13, said panel pivotally mounted to said turntable
so as to be
movable between a vertical position and an inwardly inclined position.
15. The apparatus of claim 14, further comprising:
an actuator cooperative with said panel, said actuator actuable so as to move
said
panel between said vertical position and said inwardly inclined position.
16. The apparatus of claim 15, said arm being in said substantially vertical
orientation
when said actuator moves said panel to said inwardly inclined position.
17. The apparatus of claim 11, said at least one longitudinal member
comprising:
a plurality of panels positioned on said turntable so as to generally form
chords of
a circle; and
a plurality of arms respectively pivotally mounted to said plurality of arms,
each
of said plurality of arms movable between a substantially horizontal
orientation and a
substantially vertical orientation.
-17-

18. The apparatus of claim 17, further comprising:
a plurality of cams respectively pivotally connected to said plurality of
arms, said
plurality of cams respectively cooperative with a surface of said plurality of
arms such that an
inward movement of said plurality of panels causes said plurality of arms to
move toward the
substantially vertical orientation.
19. The apparatus of claim 11, further comprising:
a levelwind positioned in spaced relation to said turntable, said levelwind
movable so as to cause the tubing to helically wrap into a coil around the at
least one longitudinal
member.
20. The apparatus of claim 11, further comprising:
a winch positioned in spaced relation to said turntable, said winch suitable
for
drawing the tubing across said turntable.
