<p>The device has a loosening tool (1) having a grid-like design so that its grid level can execute a movement. The tool is arranged perpendicular to the direction of the insulation (5), so that a feeder because of its movement through the grid-like loosening tool (1) has a depressed part arranged with bars, which are perpendicular to the direction of moving tool. An independent claim is included for use of the device.</p> |
