Abstract (en)

Process and machine for making a bag made of paper material for packing articles, which comprises a step of coupling a first strip (5) with a second strip (6), in order to direct them along a main work axis (X); a gluing step in which, on the second strip (6), a plurality of gluing lines (8) are placed that are transverse with respect to the main work axis (X) and a longitudinal gluing line (9); a cutting step, in which the first strip (5) and the second strip (6) are cut along cutting lines orthogonal to the main work axis (X) and superimposed on the transverse gluing lines (8), in a manner such that each cutting line defines a lateral margin (103) of a bag and a lateral margin (103) of a subsequent bag along the main work axis (X).
