The present invention relates to a soft roll material-translating device for the mechanical apparatus of machining and cutting after severing. The existing pillow type of automatic packing machine can only pack produces using one single roll of film, so the work efficiency is low. Consequently, the present invention aims at improving the work efficiency and it adopts following technical solutions: the soft roll material-translating device includes a frame (1), a right rotating unit (3) with right folding rod pair (5) and a left rotating unit (2) with left folding rod pair (4) are mounted on the frame (1), the right rotating unit (3) and the left rotating unit (2) can both rotate around a rotating center. By adding a few of mechanisms, the work efficiency of the device can be multiplied one times.
