Abstract: An arrangement for feeding soldering material into a space between a bolt and rock includes a sleeve-like nozzle which can be pushed tightly against a feed chamber on the rock bolt so that a feed hole in the feed chamber is connected to the inner space of the nozzle. The arrangement further includes a device for placing the nozzle around the feed chamber so that soldering material can be fed from the inner space of the nozzle into the drill hole.
