Abstract
The invention has as its object a method for packing a welding wire (25) inside a container (40) which includes at least the following steps: a feeding phase of said welding wire (25) inside a tube (13) placed in rotation to produce a prefixed torsion at each wire loop (25); a winding phase of the wire (25) coming out of said tube in rotation (13) on a core (20) configured to wind said wire (25) on it, said core (20) being provided with an alternative movement in a substantially vertical direction; a wire cutting phase (25) at the end of said wire winding phase on the core to (20) and; a core pick-up phase with the wire (25) wound on it and a core introduction phase (20) with the wire (25) wound on it inside a container (40).

A method for packing a welding wire inside a container, said method comprising the following steps:
- feeding said welding wire inside a tube that rotates to produce a plurality of wire loops, each with a prefixed torsion;
- winding said welding wire exiting said tube about a core disposed on a rotatable platform such that the platform is capable of rotation about a rotation axis to therefore rotate said core and produce a winding of said plurality of wire loops wound about said core, wherein said core is further moveable upwards and downwards in a substantially vertical direction along the rotation axis, so as to allow winding of several layers of wire formed by loops of increasing diameter, until reaching a desired band width of a coil formed by the wire loops;
- cutting said welding wire after said winding on the core;
- picking up said core with the winding wound on it;
- and
- positioning the core with the winding wound on it inside a container,
- wherein said feeding said welding wire inside a tube that rotates to produce said plurality of wire loops comprises a roller system pushing said wire into said tube, further comprising placing a flange on a top face of the core after said winding and prior to said picking up and attaching an end of said wire to a fixing hole in said flange.
A method for packing a welding wire inside a container, said method comprising:
- feeding said welding wire inside a tube that rotates to produce a plurality of wire loops, each with a prefixed torsion;
- winding said welding wire exiting said tube about a core disposed on a rotatable platform such that the platform and core are capable of rotation about a rotation axis, to produce a winding of said plurality of wire loops wrapped about said core, wherein said core is further moveable upwards and downwards in a substantially vertical direction along the rotation axis, so as to allow winding of several layers of wire formed by loops of increasing diameter, until reaching a desired band width of a coil formed by said welding wire;
- cutting said welding wire at the end of said winding on the core;
- picking up said core with the winding wound on it;
- and
- positioning the core with the winding wound on it inside a container,
- wherein said feeding said welding wire inside a tube that rotates to produce said plurality of wire loops comprises pushing said wire into said tube,
- the winding has a cylindrical or truncated cone shape, and
- further comprising freely rotating said platform thereby rotating said core about said rotation axis, said core rotating in the same direction of rotation as said rotating tube, wherein the rotation axis of said core is aligned with an axis of rotation of the tube, and
- further comprising placing a flange on a top face of the core after said winding and prior to said picking up and attaching a cut end of said wire to a fixing hole in said flange.
