Equipment and method for changing a blade

Equipment for changing a blade, which blade is intended to be used in a blade holder (10) in connection with doctoring or coating a surface, and which is preferably arranged as a flexible band (16) with one or several blades, the equipment including

• a first reel (14) in connection with one end of the blade holder (10), for keeping the unused band (16) reeled,
• a second reel (15) in connection with the other end of the blade holder (10), for keeping the used band (16) reeled,
• transfer devices (18) for moving the band (16) in the blade holder (10) between the reels (14, 15), and
• guide devices (17) for guiding the band (16) from a reel (14, 15) to the blade holder (10) and/or from the blade holder (10) to a reel (14, 15), which guide devices (17) are arranged to turn the band (16) longitudinally to be essentially parallel to the blade holder (10),
• characterized in that the guide devices (17) also include guide members (20, 20′) set on the same line at a distance to each other, between which the band (16) is unsupported, and the guide member (20′) closest to the blade holder (10) is in a position rotated in relation to the longitudinal axis of the band (16), which essentially corresponds to the position of the blade holder (10) turned to the blade-changing position, in which position the blade is off the surface being doctored or coated.
