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.

A fall arresting device including a device housing, a shaft within the housing, a rotor assembly rotatably connected to the shaft that includes a drum and a disc having at least one region of a ferromagnetic material, an extendable lifeline connected to the drum, a magnetic sensor positioned stationary relative to the device housing and adjacent to the disc, and a that includes a hard-magnetic material. The magnet positioned stationary relative the device housing and the magnetic sensor, where the magnetic sensor is configured to detect a change in a magnetic field produced by the magnet when the disc rotates about the shaft, the change in the magnetic field induced by the at least one region of the ferromagnetic material being brought within close proximity to the magnet as the disc rotates.

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:
