摘要

A corrugated cardboard box making machine wherein the units such as feed unit (1), printing unit (2) and slotting unit (3) are separably connected in alignment with a driving shaft (7, 8, 9) being provided on each one of the units. On one element (29) of a coupling (27, 28) arranged between the driving shafts are provided engaging projections (34), and on the other element (30) there are provided engaging concave portions (41) to automatically receive under the pressure of spring 38 the engaging projections only when rotational positions of both of the elements coincide. The machine is further arranged to automatically and accurately perform connecting operation of each driving shaft when each unit is reconnected after such work as printing plate exchange is finished.
