To provide a strip manufacturing facility by which each edge drop part can be reduced together with a central part and the edge drop part can be left on the exit side after rolling even if there is a large edge drop part on a strip of the entering side and the sizes of the right and left edge drop parts are different.

The strip manufacturing facility is provided with a rolling mill 10 which has a pair of upper and lower work rolls 20 for reducing a slab material 1 having the edge drop part 2 on both end parts and a pair of upper and lower stand-by rolls 30 for suppressing the deformation of the work rolls. The work rolls 20 have a inverted taper part 24 in which the diameter of the shaft end side is gradually enlarged to a barrel end part corresponding to the edge drop part. The upper and lower work rolls are constituted so as to be capable of separately and axially shifting. The stand-by rolls 30 have a relief part 34 in which the diameter of the shaft end side is gradually reduced so as not to come into contact with the inverted taper part of the work rolls in the shift range of the work rolls.
