A scoring and cutting apparatus for an elongated sheet member supplied continuously in a longitudinal direction thereof for forming longitudinal score lines and cuts, respectively, at desired intervals of width. The apparatus has a construction comprising a plurality of injection nozzles for cutting the sheet member which are connected to a high pressure liquid supply source and are disposed to form at least two rows extending transversely relative to the moving direction of the sheet member, and a plurality of scoring rolls are also disposed to form at least two rows extending transversely relative to the moving direction of the sheet member, and a plurality of scoring rolls are also disposed to form at least two rows extending parallel to the rows of the projection nozzles, the rows of scoring rolls each being arranged to be movable upwards and downwards between respective inoperative and operative scoring positions. The projection nozzles in each row are slidable for adjusting the transverse spacing therebetween and the scoring rolls are also slidable for adjustment of their transverse spacing.
