PURPOSE:To make it possible to simply turn over a sheet-like material even having a long length and a heavy weight, by replacing the positions of a pair of feed rollers with respect to each other after the rollers feeds the sheet-like material. CONSTITUTION:A sheet-like material S of a predetermined length is fed by a pair of upper and lower feed rollers 13, 14 to suspend down the sheet-like material S from the feed rollers 13, 14 at the feeding front side thereof, and this feed is stopped just before the time when the trailing end of the material S reaches the nip section of the rollers 13, 14. Then, a turning geared motor 17 is driven to turn a turning bracket 12 by 180 deg. in the direction of the arrow P about a pivot shaft 12a as a rotating center for replacing the positions of the pair of upper and lower feed rollers 13, 14 with respect to each other so that the sheet-like material S is suspended down from the rear surface of the upper roller 14 positioned in the lower side, thereby the trailing end of the sheet-like material S is projected in a short length forward from the nip section of the feed rollers 13, 14. Then, the feed rollers 13, 14 are again rotated to extract forward from the trailing end of the sheet-like material S which is therefore turned over and then fed out forward.
