ABSTRACT:
A device for storing wire in a wire bolting arrangement, which device comprises a reel which supports a ring-shaped wire coil, and a supporter on which the reel is mounted for rotation. In order to prevent unintentional unwinding of the coil, and in order to simplify the replacement of the device, the reel is formed as an essentially closed housing which encloses the wire coil and which is provided with a central opening for drawing out a wire. The housing and the supporter are preferably formed as a separate, replaceable cassette fastened on the carrier of the bolting means.
