(EN) A carton forming machine for automatically erecting cartons (C) on a continuous basis wherein the cartons are of the type coated with a heat sealable plastics material. A single forming well (22) is provided and forming heads (24) carried by an endless conveyor (37) repeatedly move carton blanks (B) through the forming well (22) to effect the erecting thereof, followed by the heat sealing of flaps (11) to maintain the erected state of the cartons, followed by the taking away of the cartons and stacking the same. The formed and erected cartons (C) are stripped from the moving forming heads (24) by stripper elements (55) moving in the same direction and at a greater speed than the forming heads.
