Claim:
Equipment for changing a flexible band forming a doctor blade, in a blade holder, the doctor blade for doctoring or coating a roll surface, comprising: a blade holder having a first position for holding the doctor blade against the roll surface and a second position for accepting a blade change which is rotated from the first position so in the second position the doctor blade is not held against the roll surface; a first reel having a flexible band reeled therein in supplying relation to a first end of the blade holder; a second reel in receiving relation to a second end of the blade holder opposite of the first end, for reeling used flexible band; a transfer device for moving the band between the first reel, the blade holder, and the second reel; and a plurality of guide devices for guiding the band from the first reel to the blade holder wherein the guide devices are arranged to turn the band longitudinally to be essentially parallel to the blade holder; and wherein each guide device has a first guide member distal from the blade holder and a second guide member proximal to the blade holder, the first guide member and the second guide member are alined along a line at a distance to each other, without band supports extending therebetween, and the second guide member closest to the blade holder is in a position rotated in relation to a longitudinal axis defined by the band, which essentially corresponds to a position defined by the blade holder turned to the blade-changing position, in which position the blade is off the roll surface doctored or coated, wherein the first guide member and the second guide member are connected by a closed channel.
