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).

An apparatus (100) for making a coil (B) comprises a feed unit (2) configured to feed at least one strip-shaped article (N) and a winding unit (1). The feed unit (2) comprises a movable portion (20) that includes an outlet section (22) through which said strip-shaped article (N) passes through. The winding unit includes a plurality of winding heads (10) and a movement device for moving (3) said winding heads (10) configured to displace said winding heads (10) along a working path (P). The winding heads (10) and said movable portion (20) are both movable.

Disclosed within are various embodiments that provide for an automated rod coil cutting station for both ferrous and non-ferrous wire rod mills.

Provided are methods that can prevent either or both of kinking and collapsing of a steel sheet coiled in coil form regardless of the characteristics of the steel sheet. A method of determining a tension pattern of tension applied to a steel sheet to coil the steel sheet in coil form comprises calculating the tension pattern using an apparent elastic modulus in a radial direction of a coil.

An assembly device for assembling or pre-assembling wire portions includes an arrangement device detachably attached to the assembly device to receive the assembled or pre-assembled wire portions. The arrangement device includes a main body and a slit at least partially extending along a longitudinal extent of the main body to string the wire portions along the slit. The arrangement device includes an adjustment device for adjusting a slit width of the slit.
