Abstract
A method of coiling steel rod arriving continuously comprises the steps of rotating about an upright axis a coiling basket defining a space centered on the axis and defined by an annular inner wall, an annular outer wall, and a floor between the walls, and feeding the rod into the space to form a coil resting on the floor and formed by a multiplicity of turns. The coil is, once formed, raised out of the space and simultaneously axially compacted and is also stabilized. More particularly the coil is stabilized by spraying an outer surface of the coil with a coolant while raising the coil out of the space. Normally the coil is rotated about the axis as the coil outer surface is being sprayed.

A method of coiling steel rod arriving continuously, the method comprising the steps of:
- rotating about an upright axis a coiling basket defining a space centered on the axis and defined by an annular inner wall, an annular outer wall, and a floor between the walls;
- feeding the rod into the space from a laying pipe closely juxtaposed with the floor to form a coil resting on the floor and formed by a multiplicity of turns;
- raising the coil out of the space and simultaneously axially compacting the coil;
- and
- cooling only an outer surface of the compacted coil and thereby stabilizing the compacted coil.
An apparatus for coiling steel rod arriving continuously, the apparatus comprising:
- a coiling basket defining a space centered on an upright axis and defined by an annular inner wall, an annular outer wall, and a floor between the walls;
- drive means for rotating the basket about the upright axis;
- guide means including a laying pipe closely juxtaposed with the floor for feeding the rod into the space to form a coil resting on the floor and formed by a multiplicity of turns;
- at least one abutment vertically downwardly engageable with the coil;
- means including an actuator for raising the floor and pushing the coil up out of the space against the abutment to axially compacting the coil;
- and
- means above the basket for spraying a coolant against an outer surface of the coil and for thereby stabilizing the compacted coil.
