Summary:The invention relates to a feed apparatus for feeding capsular cartridges into a drilled hole, the apparatus being intended to be used in conjunction with a rock drill apparatus. The feed apparatus comprises a rotatable roll-like cartridge magazine (1) with charge tubes (2) which are arranged on at least one perimeter and into which the capsular cartridges can be loaded in advance. The apparatus further comprises means for indexing a magazine, whereby the desired charge tubes (2) can be rotated to align with the feeding line. In an embodiment of the invention the feed is performed by feeding pressure air into the rear end of the charge tube at a high pressure, whereby the cartridge loaded into the charge tube moves from the charge tube to a connecting pipe (7) positioned at the firing line at the front end of the cartridge magazine and further along a feed hose 86) to a hole drilled in advance. The apparatus can also comprise a control apparatus for automatic control of the feed apparatus from the cabin.
