Abstract
Machine for making packing boxes, by means of cutting and/or pre-creasing operations on a sheet (F) of sufficiently rigid material, comprising feed rolls (15, 16), able to move the sheet (F) forward in a first longitudinal direction (L). A first working head (21) is mobile in a transverse direction (T), substantially perpendicular to the longitudinal direction (L), in order to make transverse cuts and/or pre-creasings on the sheet (F). A group of second working heads (41) can be positioned along the transverse direction (T), in order to make longitudinal cuts and/or pre-creasings. A positioning device (75) is disposed on the first working head (21), able to cooperate with each second working head (41) in order to selectively position it in the transverse direction (T).
