Carton Slitter And Forming Machine

The device slits and creases the end flaps of cases or containers. The height of the crease and the depth of the slit are determined by the height of the highest article in the container.

The device carries a set of four knives 70, fixed in four guiding block segments 42 and expandable in radial direction with regard to the axis of a supporting rod 24. It also comprises a punch assembly 21 and a die assembly
23.

By a conveyer belt, a carton is placed under the slitting and creasing device. The latter is then lowered until the plate 38 engages the top of the highest article in the carton. Then, collar 26 and the plate 38 connected with it are stopped. In this position, the flaps of the carton pass between the punch assembly 21 and the die assembly 23. Continued downward movement of the support rod 24 moves the segments 42 radially in the outward direction. The knives 70 first pierce and then slit the corners of the carton. Substantially simultaneously the top of each of the segments 42 engages each flap and starts it outwardly. The bottom of each segment 42 then creases the flaps over the creasing flange 36.
