US 6,149,091 A · Coiling method and relative device

Abstract

Method to coil metal wire made of steel arriving directly from an in-line rolling plant, in which the metal wire is delivered to a rotating loop-forming head (11) cooperating coaxially with a hollow drum (12) to form the coil (13), the hollow drum (12) having a controlled rotary movement, the relative speed of the loop-forming head (11) and the drum (12) together being functional to the layer being formed, the drum (12) being associated with an alternate axial moving system. Device to coil metal wire made of steel arriving directly from an in-line rolling plant, comprising a rotating loop-forming head (11) associated with a mating pinch roll device (15) to feed the wire being coiled, and cooperating coaxially with a drum (12) to form the coils (13), the drum (12) being associated both with means to supply a controlled rotary movement and also with an alternate axial moving system (14), the rotation of the loop-forming head (11) and/or drum (12) being a function of the coiling step and the speed of feed of the wire being coiled.

Method to coil metal wire made of steel arriving directly from a high-speed in-line rolling plant, comprising delivering the metal wire from the high-speed in-line rolling plant along a substantially horizontal axis to a loop-forming head cooperating with a hollow drum, coiling the wire by rotating the loop-forming head at a first speed and rotating the hollow drum at a second speed to form the coil, wherein an axis of rotation of the loop-forming head and an axis of rotation of the hollow drum are not substantially vertical, the relative rotation speed of the loop-forming head and the drum together being a function of the layer being formed, and axially moving the hollow drum with respect to the loop-forming head during formation of the coil.

Coiling device for metal wire made of steel arriving directly from an in-line rolling plant along a substantially horizontal axis, comprising a rotating loop-forming head, an axis of rotation of the loop-forming head not being substantially vertical;

a mating pinch roll device to feed the wire to be coiled to the rotating loop-forming head;
a drum in which coils formed by the loop-forming head are deposited, an axis of rotation of the drum not being substantially vertical;
means to supply a controlled rotary movement to the drum;
and an axial moving system for axially moving the drum with respect to the loop-forming head during formation of the coil, the rotation of the loop-forming head and of the drum being a function of the coiling step and of the speed of feed of the wire to be coiled.
